Flying Ants


2nd October was “Flying Ant Day 2013” here. That was the day when the ants with wings left their nests. The day varies each year because it always follows the first  rains  that end the summer dry spell. Every summer is always dry, but they are not droughts such as are experienced for example in Australia and USA. The first rains also bring a drop in temperatures.

Weather forecasts are much more accurate than they used to be and I knew about a week in advance when the rain would begin. This is very useful information because it allows time to deal with work that absolutely must be done in advance of it happening. For me that meant removing the irrigation pump from the river as the first priority. I always leave it in position until immediately before local rain, because being an optimist, in the years when the river stops flowing I hope for sufficient of a thunderstorm somewhere in the mountains at the top of the catchment area will begin the river flowing whilst we are still dry. It did happen one year. Harvesting fruit and vegetables that are ready comes next. Figs and tomatoes are particularly prone to splitting with a sudden influx of water after they have been dry for so long. Olives are also at risk, but I had been carting out water in the tank of my boom spray to supply a little to those trees where the fruit was beginning to shrivel and I hope I have prevented damage.

There was a little rain early on the morning of 27th September with another 53mm falling during the day and a further 50mm over the next couple of days. Temperatures tend to be fairly static on a daily basis, changing little from one day to the next. It is rare to get a change of more than two degrees on consecutive days, but the rain makes one of the two exceptions in the year. Temperatures had been a degree either side of 31ºC up to the 23rd with slight falls as the clouds moved in and a drop to 21º when the rain began. It felt decidedly cool the first day, despite the fact that I consider that temperature to be very pleasant most of the time. There is a similar fairly sudden change each year in May when we begin to receive warm southerly winds and the shade temperatures increase. It is always warm in the sun, even in the depths of winter.

On the 2nd October around 10 am the ants began to take to the air. I had seen the numerous holes that appear around nests earlier in the morning and a few winged ants coming out of them. For a few hours they were on the wing, but not as numerous as in other years. Perhaps my efforts at destroying nests on the quinta is beginning to have some effect. Our biggest problem is the Seed-harvester Ant and they cause considerable economic loss so I spend some time searching out nests and killing the occupants, but many nests have only a single entrance/exit that is often covered through the summer heat and it is difficult to find them.

These ants do exactly what their common name suggests – they harvest seeds. Millions of them. I have lost all seeds sown in the garden on more than one occasion, and when I can spot the ants in the process I follow them to their nest, but a hundred feet of small seeds can disappear overnight. They also cart away many kilos of grass and clover seeds when fields are sown. They have no problems whatsoever with cereals, maize, smaller beans and even White Lupins. I have not yet seen an ant carrying a Broad (Fava) Bean. I have also lost about 20 young olive trees to ants building their nest in the rootball of newly planted and young trees and the tree dies. The Seed-harvesters are not the only culprit in these losses though, because there is a much smaller ant (no idea what it is) that likes to do the same.

In previous years there has always been an ant to approximately each square foot after they land. This year it was less than one to the square yard. They always drift downhill on this property whereas it seems they normally swarm towards higher points. Their behaviour is similar to that of the honey bee when a new Queen emerges and drones fly to mate with her in the air. Whilst the male ants still very much outnumber the females, there are many potential Queen Ants on the wing. Fortunately most of them fail to establish a nest. As with bees, the males merely die.

There is a lot of information on the internet for those interested, simply search the term “flying ants” and included, for those specifically interested in Portugal or Spain, there is a very good and easily readable paper with the title beginning “Nuptial flights of the Seed-harvester Ant (Messor Barbarus) in the Iberian Peninsula………” by Gomez and Abril of the University of Girona and published in the Myrmercological News of January 2012.

Feeding and watering olives


Olives will grow and fruit in a wide range of soils, even under arid conditions. Tree spacing is less in modern groves than it was historically, when trees were frequently planted around the Mediterranean at 12 x 12 metres spacing. Ignoring super high-density groves where the trees are close spaced for “over the top” harvesting with machines, it is currently usual to plant at distances between 5 x 5 to 7 x 7 metres.

Temperature constraints are that damage will occur below minus 6ºC.   Severe damage, and perhaps trees killed, occurs very little below that, but, like many species of fruit and nuts, olives have a chilling requirement  – i.e so many hours of temperatures below 7ºC,  (45ºF for those who use Fahrenheit) before they will flower the following spring. How many hours each cultivar needs is variable, and it seems extremely little research has been done. No doubt cultivars evolved to suit the environment in which they are found naturally, and a failure to reach the chilling requirement of any cultivar means that flowers will not bloom. A mean daily temperature below 12ºC for several weeks seems sufficient to meet the chilling requirement of all cultivars. How many weeks is open to debate.

As with all plants, better quality soil, adequate nutrients and adequate water lead to much more production. Soil is usually a “given” for most people, and, within the temperature ranges required, almost any soil can be made to grow olives. Millions of trees have been planted in individually terraced planting spaces on very steep hillsides. If looking to buy a new property specifically for planting olives, then somewhere with a good depth of soil, say at least a metre and not solid clay, and plenty of available water for irrigation are the main requirements.

With limited knowledge of olives, and a desire to begin a non-animal enterprise when we first bought our present property, I was led to plant a grove at 6 x 6 metres spacing. I am quite happy with that and have planted more since at the same spacing. This works out at 277 trees/ha of planted area. Over the last 10 years I have read an enormous number of articles, research papers and advice from a huge number of people and organisations involved in olive production in probably every country in the world where olives are grown, as well as spoken with several knowledgeable people. I have made decisions, based on all this information, that I use to provide food and water for my trees. Whilst at least one expert agrees with each individual decision - because I have chosen to follow at least one expert’s advice in everything I have decided, some will disagree with my overall management, but then they disagree with each other, ranging from extremely little fertiliser to extremely high levels, and from allowing quite severe moisture deficiencies (at times) to maintaining full moisture profile of the soil.

Note that being in the northern hemisphere the calendar year begins a few days after mid-winter, so southern hemisphere information that refers to dates is in the reverse production cycle position. Based on soil analyses, fertilisers used and crops grown in the groves since the previous analysis, I apply granular fertiliser as soon as practicable in the year. I top up phosphorus(P) and potassium(K) if necessary. I apply Nitrogen(N) according to a personal assessment of how much to apply. I may have grown a winter leguminous crop for harvesting or for incorporation as a green manure. Alternatively, a crop of maize may have been grown the previous summer and the stover left on the surface as an overwintering mulch; or a summer leguminous crop may have been sown and either harvested or ploughed in. I am also conscious of the requirement for adequate trace elements without fertilising to excess.  I have used foliar feeds, sometimes called foliar fertilisers, this year and propose to make them an integral part of my fertiliser programme. I will use high N early in the year and low N as the fruit matures. I may apply a second dose of N granular fertiliser in the spring too – again depending on a personal assessment of need. I prefer to split fertiliser into smaller doses rather than apply a full season’s requirements at once, but this is not always practicable. I will aim to have a pH of 7 or slightly above. Somewhere in the range of 6.5 to 8 seems to be preferred, but as I said, the experts do not always agree on the ideals

The groves are irrigated, either through drip irrigation or overhead sprays. The drip system is a single line with four litres/hour drippers at one metre spacing and laid on the ground. The different irrigation methods determine what I can and cannot grow in the summer. With overhead I can grow crops between the rows. With drippers I am limited in summer, but not winter. I still intend to grow comfrey on these lines (to be cut and used as a mulch for the trees) but this might be delayed for another couple of years because the weed seed bank in the soil is still too high.

There is nothing I can do about the texture of the soil I have except to increase the Organic Matter(OM) content. Higher OM means a soil that is more capable of retaining both nutrients and water. Many semi-arid and arid soils have an OM content of 1% or even less but, from anecdotal information only, it seems that the highest yields come from trees grown on land with OM of several percentage points. I will also avoid bare soil as much as possible, endeavouring to maintain some ground cover to stop the possibility of water erosion in winter despite the fact that I have not experienced this happening, and to ameliorate high soil temperatures in summer.  This means cultivating as infrequently as possible – anathema to some growers who insist on permanent bare land cultivated regularly throughout the year.

The sole reason behind my decisions is the way in which the olive tree grows and produces its fruit. The following three paragraphs are a combination of information in a University of Cordoba, Spain publication and a paper by Razouk et al, with the long title of “Optimal time of supplemental irrigation during fruit development of rainfed olive trees in Morocco” with some additional comments based on other information I have sourced.

Yield of olives is the result of three main developmental processes that occur from flowering to harvest:  fruit set, fruit growth and oil accumulation in the fruit pulp. Vegetative growth is critical in terms of olive fruit production, because flowers are borne in inflorescences at the axil of leaves of one-year old wood. This means that flowering and fruit set originate in the axillary buds of last years growth. So, the big problem is ensuring that this year’s fruit crop has sufficient nutrients to yield a heavy crop of large (for the variety) olives, but at the same time producing sufficient growth of new wood for next year’s crop. In less than optimum conditions one or the other, or both, will suffer. This is one of the reasons why there is so much biennial bearing in olives. New growth is restricted by the demands of a heavy crop on the tree, but flourishes when the previous year’s poor growth carries a small or nil crop, and the tree produces another good crop in the following year. A vicious circle.

The reproductive cycle from flower bud initiation to fruit ripening takes 15-18 months depending on cultivar and growing conditions, as initiation starts in one summer and fruits from this initiation ripen in the autumn or winter of the following year. The terminal bud of a shoot is almost always vegetative and shoot growth starts with this bud break in spring, when temperatures rise above 12ºC. Growth continues as long as temperatures are below 35ºC, and there are no soil water deficit or other environmental stresses. Growth begins pre-flowering, but natural soil water supplies are almost always sufficient to avoid the need for irrigation at this time. Critical stages for the tree are flowering in April/May; a time of rapid growth about mid June; pit hardening about the end of July or early August, and a second rapid growth about mid September. The first rapid growth stage occurs just as most Mediterranean soils are becoming water deficient for the summer. Pit hardening and the second rapid growth stage are well and truly in the dry summer and early autumn before the winter rains begin. Some fortunate areas receive some summer rain. Pit hardening is about the time of flower initiation for next year’s crop too, so a lot of stress on the tree at this stage. The growth stages and fruit development were the factors considered by Razouk and his associates.

So, back to why I do what I do. I rely on soil analyses in preference to leaf analyses. The reason for this is simple – the chemical and nutritional composition of any particular leaf changes throughout the year, and younger leaves have a different composition to older leaves. Because of these changes I believe that leaf analysis is of less value than soil analysis for long term planning. We could obviously become super technical and do all sorts of tests, but that is for research scientists, not your average grower. Some sources of information, particularly those selling foliar feeds, insist on using leaf analysis (taken in July each year) as the decision maker in fertiliser requirements. Following the work of some researchers, maintaining the soil at adequate levels of all plant nutrients is recommended – bearing in mind that an excess of some can prevent an uptake of others, even although they are available. I take an approach that if levels of the macro nutrients are considered adequate by most authorities I am probably offering my plants the best that can be reasonably done by any farmer.

I agree with those who say that applying foliar feeds shows an almost immediate response, whereas granular (or liquid) fertiliser applied to the soil may not. At the same time it is not a lasting effect – similar to the application of prilled lime, which is a very finely ground limestone that is formed into prills the same as granular fertilisers and break down rapidly after application to the land. This gives a quick fix to a low pH but does not have the ongoing pH correcting ability of coarser ground limestone. The same applies to the foliar feeds, they raise nutrient levels within the aerial part of the tree for a short period of time. I do, though, go along with the school of thought that foliar feeds assist the plants to assimilate nutrients from the soil. P in particular can be a problem for plants to take up because it is fairly immobile in the soil, and it appears that applying foliar N can assist with that problem, although it also seems sensible to have some P in the feed. Foliar feeds do not replace the soil nutrients, they complement the soil supply. You cannot feed a tree just through its leaves.

I apply N fertilisers to the soil so that the tree has the nutrients to produce fresh young growth in early spring, and will apply a high N foliar feed, containing P, K and trace elements, as a booster pre-flowering, possibly a second high N foliar feed too. Some authorities believe that Boron(B) should be applied pre-flowering. Both compound fertilisers and foliar feeds that I use contain some B and I am not inclined to add more as a special feed unless I apply only N to the soil when I might mix some additional B with the foliar feed. B is toxic to most living things at fairly low levels – it is used by people who do not like “poisons” in order to kill ants. It certainly is a poison (as are most things) above certain levels. If I think the pH level needs raised, I will include lime when filling the fertiliser spreader with the granular N or compound fertiliser. Lime spreads easier when mixed with granular fertiliser.

Provided the trees are growing well there will be no further fertilisers applied specifically for the olives until late summer, but any crops grown between the rows of trees will be fertilised independently of the needs of the olives, and some of this is available to the trees. After pit hardening I will apply at least one and probably two foliar feeds with lower N and higher levels of P and K, plus trace minerals. It is convenient to apply these foliar feeds with sprays against olive fruit fly – a necessity where I live. There are so many untended groves that all olive pests and diseases are able to proliferate and a failure to treat against them results in enormous crop losses, sometimes total failure. It is also necessary to spray against a fungus that can cause total crop loss too and this is done nearer harvest. Again it is convenient to add a foliar feed with these sprays if desired.

I use the overhead spray equipment for irrigation primarily because I have it and it suits me to use it in a grove which I can summer crop. The drippers were installed to meet the needs of a new grove, but using existing pumps and underground main lines. I have the dripper lines on the surface because I prefer them where I can see them and I make an inspection as soon as I begin an irrigation. That way I can spot any problems along the lines and fix them immediately without switching off the pumps. An underground line that suffers damage will not show up until the water begins to puddle on the surface, which undoubtedly means some trees have missed out on their water, and it is necessary to dig up the line to mend it. There is also the problem of where to bury the line. In the early years the trees occupy only a small area of the soil so the drippers need to be relatively close. As they grow, the lines are moved back from the trees and the trees make use of additional drippers as they spread their root zone.

Not all the water I currently pump is utilised by the trees, but it will be in time, and until then I make use of drippers outside the root zone by sowing pumpkins and squashes as  feed for the goats, as well as some household use and also tomatoes, cucumbers, melons, etc. immediately adjacent to a dripper. In previous years I have also sown the drought hardy black eyed peas between the rows and they have benefitted from the water from the drippers, particularly those peas close to the drip line. The site is a very slight slope so the water naturally travels downhill and the drip line is uphill of the row of trees it supplies. Both types of irrigation are left in their permanent positions. Hand harvesting means there is no need to move the lines off the fields.

Irrigation commences around mid-June every year for the whole property, which makes it convenient for the first irrigation requirement of the olives – unless there has been a particularly dry spring when an earlier start to the irrigation season may be required. There is always plenty of water available in the early summer, and this first irrigation has been found to be the most beneficial from an economic perspective. It assists both the current crop and the ability of the tree to produce growth for next year. It is more valuable than the water needed at pit hardening and the second rapid growth stage. This is a most fortuitous situation, because those relying on natural water supplies, as I do, may run out of water if the winter and spring rains were low or ceased early.

My strategy then is to maintain a good soil moisture level as long as possible, and of course other summer crops grown in the groves need this water. My theory behind this is that if I run out of irrigation water, then the more there is in the soil the longer it will be before moisture stress affects the crop. I know from my 2012 maize crop that it was successful without irrigation from silking onwards. The olives did not receive their pit hardening and mid-September water that year. Provided I have the water I will continue to irrigate past the second flush of growth, but in 2013 the last irrigation was just after pit hardening. Reducing irrigation earlier in the season does not prolong my season, being dependent upon a river continuing to flow.

For those with water storage, Razouk showed that a large quantity applied at the first rapid growth stage (he used 500 litres per tree, on mature trees) can be followed by the next at pit hardening, and preferably a third at mid-September. If there is storage for only one irrigation, or natural supplies only into the early summer, then apply water in June. Whether water is available or not I will cease irrigation at the end of September. This allows time for the fruit to mature without containing too much water - which would result in a lower oil content, giving a poor yield of oil for the fruit weight. This is extremely important for anyone paying a contractor crusher to produce their oil and charging, as apparently many do, on the weight of fresh fruit rather than yield of oil.

2013 to date.


I do apologise for the last post not really being a blog, but I felt I had to post something after almost three months since the previous post, and I had those snippets ready in a document intended to be used in an advertising campaign.

Weatherwise, 2013 began as 2012 had ended – very mild. 2012 had a mean temperature of 15.33ºC for the year, the third warmest since we came here in 2003, with 2011 at 15.90ºC and 2010 at 15.75ºC being the two warmest. Overall, the 2012/13 winter was very pleasant, with extremely few frosts, and only a couple of recorded negative temperatures, with the lowest minimum only –1ºC. The first few years we were here we regularly recorded minus fives and sixes each winter, with one minus seven. Temperatures elsewhere were even lower that night and there were widespread losses of olive trees and eucalypts across the whole country. Virtually everyone thinks of Portugal as a prime holiday spot in summer and few realise that skiing is possible in the winter. The Serra da Estrela (about 40 miles from us) has a ski lift.

As I said at the beginning of the previous blog we had a prolonged spell of wet weather. In the 8 weeks from 18th February we had 352mm of rain, and just as things were looking hopeful for a very late start to spring work, we had a downpour of 15mm in a few minutes on the 27th April. It then turned cold and we had overnight minimums down to 6ºC into the last week of May, with little progress upwards until well into June.

Conditions in March, April and early May were so wet that at the lower end of underground land drainage pipes the water was being forced to the surface because it could not flow sufficiently quickly through them. Being at the bottom of the river valley means there is a considerable amount of underground water moving through the property from higher up the hill. Then, of course, it stopped raining as it always does for the summer.

Growing cold weather crops is somewhat easier than warm weather ones where the soil temperature needs to reach a certain level before the warm season seeds will germinate. The long cold and wet spring also meant that the broad beans (Vicia faba) continued flowering and growing on when they should have been maturing. It meant a heavy crop, but also primed the late spring weeds – mainly a very large crop of corn marigolds and several species of the daisy family. I always find it interesting on the farms I have owned to see the way the weed spectrum changes with the improving fertility of the soil. I do not recognise the different species of these daisy type flowers (several of them are possibly types of Chamomile from the scent) but they come in all sizes up to about 1 metre tall and have masses of flowers each containing an enormous number of seeds.

The prolificacy of the weeds, insects and fungal diseases of crops, plus the relatively mild winters so that they all thrive, has left me deciding to forget any ideas about being organic (even in the kitchen garden) and I now spray as necessary. The winter beans in particular benefited from a fungal treatment early in the year. Some were left untreated due to not being able to walk on the ground because of the excessive rain, and they succumbed without producing anything. I have lost previous crops to the same problem. I have three knapsack sprayers, and it is heavy work and very slow with constant refilling of the sprayers, so I am purchasing a tractor mounted one.

Unfortunately producing the crop is only part of the process, and due to an old and ongoing knee problem that has been exacerbated by the hand picking of the beans I have been unable to complete the harvest. The unharvested portion of the crop has been cultivated into the ground and will produce a green manure crop when the beans germinate with the autumn rains. I have a horrible feeling I shall have to accept that old age is catching up with me and that I can no longer do everything to which I have been accustomed. I usually walk several miles in a day working the quinta, but the knee problem has meant that I have been using the tractor just for travelling around the place. I have decided that I will not grow any more “close to the ground” field scale crops for hand harvesting, with the exception of pumpkins/squashes where a heavy weight is soon collected. Maize and olives are both at a much more acceptable height to save my legs.

The olives had a very large amount of blossom and on the whole have set a good quantity of fruit. I usually spray against olive fly and a fungal disease known locally as gafa and caused by an organism that research people seem to disagree about the spelling, but one of them is Colleotetrichum.  A failure to spray against both often results in a total crop loss, and at best a very large decrease in the crop harvested as well as oil quantity and quality in those fruit which are picked. The number of fruit bearing trees is increasing each year and I could not possibly manage with just the knapsacks.

I sowed two hectares of Piper Sudan grass and it is growing well with irrigation, but because it was late sown I will take only one cut (probably the first or second week in August) for hay instead of the usual two. The quality will be more than adequate for the goats. I was unable to get a maize crop in due to the late and incomplete bean harvest. I did manage to sow pumpkins and winter squashes along some of the olive tree lines so, with the usual winter grazing I should be able to meet the winter feed needs of the goats, but I will buy some concentrates if needed.

In the kitchen garden we had the best garlic crop I have ever grown and good results with all peas – Kelvedon Wonder, my favourite for flavour, Douce Provence and Rondo. Overwintered onions were very poor, failing to bulk up, and we will need to buy some later. I saw some fresh in the supermarket in May that looked good, and they were an excellent sweet flavour too. The variety was Reca. They are still being sold now. I think it is Spanish, and I will look for seed for overwintering this coming season. The late summer sown cabbage Spring Hero also cropped well. Asparagus was nice whilst it lasted, but a lesser crop than previous years.

I bought new seed potatoes this year, and Mona Lisa was quite early for a maincrop, beginning lifting after 12 weeks, and these will be followed by Picasso, a potato with one parent being Cara that I grew in Scotland and they look alike, white with pink eyes. Both varieties will store through the winter, but insect damage in storage is a major problem here and I will have to be vigilant.

I could not find any fresh peanuts to sow, so will have to do without our own, but several other crops are looking good – melons, Jerusalem artichokes, gherkins, cucumbers, and tomatoes (Ailsa Craig, F1Shirley and a determinate San Marzano). The curcubits and tomatoes are cropping well so far, the gherkins in particular have an enormous number of fruits – and despite a quantity having been pickled there are far more than we can use off only four plants so I have begun feeding some to the goats. They are not all fond of them at this stage, but that is not unusual with a new food. Like everyone else in the locality we have very few apples set, no peaches, plums, apricots or almonds. I know someone who grows tree fruits on a small commercial scale, and apart from cherries (apparently a low volume crop this year) he will have no other fruit.

The only new crop I am trying is Sweet Pepper. We have always eaten a very small quantity if offered to us, but both of us have usually found that they have been too hot. As previously mentioned we do not consume any spices. I found a variety, Marconi Red, that is supposedly extremely mild. So far, only a couple of “tasters” in a stir fry, and still green, it is indeed very mild. We will see how they fare as they ripen.

July is sometimes the hottest month of the year, and August in others. I hope that this year it is July because we had a spell of 37 and 38ºC although it has been a more bearable 32/33 for the last week. Time will tell. Fortunately the river is still flowing, it ceased on 6th July last year, and it was helped by some thunderstorms in the mountains on the weekend of 13th and 14th July. I would not say no to a few more, although they can be the source of fires. I am anticipating some fairly big ones this year after the wet Spring. Unfortunately many of them are deliberately lit during August and September.

Snippets


I have cheated in the preparation of this article. A long spell of wet weather up until mid-April and low temperatures thereafter left me with a very late start to a spring and summer work schedule that I cannot complete, but I must do as much as possible. That has left me no time to write a blog and the next few weeks will be no better as I have begun hand harvesting about 1.6 hectares/4 acres of beans. It is almost three months since I last posted, and that is far too long. I have been thinking what I could do instead and have a brief opportunity to post now.

Since publishing about my almost 70 years of rural living, a huge number of people around the world have accessed the book’s home page at Smashwords, and many have taken up the option of a free sample, but this sample is the opening pages and does not properly reflect the whole content of the book. So I decided to post a few later snippets that I have “on file” for proposed adverts. These snippets give blog readers an opportunity to learn about where I have been and some of the thoughts I have on rural living even if they have no interest in the book. When things slow down I will prepare a blog reporting on the year to date at the Monte.

Advice on machinery is even more difficult than livestock. One thing is certain, and that is that all machinery will cost you money to buy and keep on costing you money every time you operate it.

Simply sowing nuts can be a very cheap way to produce the trees. I planted some almonds, as well as walnuts and sweet chestnuts, in the first Autumn we were in Portugal, 2003, had a harvest of almonds in 2010 and planted more nuts from this harvest so have numerous trees for a few cents and some time.

Garlic. A necessity of life. I would like to believe the miraculous powers attributed to garlic as a preventative and curative of all sorts of illnesses and diseases.

For those who want to know, the order of courses is Hors d’oeuvres, Soup, Fish, Entrée, Remove, Game, Entremets Sucre, Entremets Savoreux, Cheeses, Desserts. We harvested olives in the November and the Hors d’oeuvres were our own olives with home baked tomato bread (incorporating tomatoes we had grown and sun-dried ourselves) and the first tasting of our first vintage.

I really do enjoy specific wines for specific courses, but at the same time I have no objection whatsoever to those who drink only whites or only reds with everything. If that is what they prefer, then that is fine by me.

SEAFOOD WITH PASTA
This can be either a starter dish or a main course depending upon quantity served. Any seafood you like, garlic, parsley and cream. Heat the lot whilst the pasta is cooking. Drain the pasta and mix everything together. Some like ground black pepper over it. Can be eaten cold as well as hot, and with a lot of cream and only a little of the seafood and pasta it makes a good thick soup course too. For a soup you could replace some of the cream with milk so that it is not quite so rich.

More about food and drink


My post about Portuguese wines continues to be very popular, so I thought I would write something more general about food and drink.

Having lived in several countries my wife and I have had the opportunity to discover a variety of dishes that are popular in certain parts of each country even though they may not be common across the whole country, and often never heard of or known internationally. This applies even more so to table and fortified wines.

I will begin with a dish that, to me, was the worst I have ever eaten. I have been presented with, and failed to eat, tripe boiled in milk, but I did manage to consume a Buckie Whelk. Now in case you are not familiar with the term Buckie Whelk, Buckie is a Scottish word for the common whelk Buccinum undatum. That is only the beginning. Buckie is a town on the Moray Firth coast of Scotland. So, combining the fact that the town is named after a whelk, and this particular species of whelk is named after the town, one can begin to imagine the size of these things. One of my idols, Max Boyce, talks about a pig coming in three sizes - big, huge and…. Duw! Well, these Buckie whelks are, as Max would say, Duw, Duw whelks. They were a gift, along with a lobster and some crabs from a Moray Firth fisherman.

We prefer crabmeat to lobster, but only just, and there is a lot more on a lobster than a crab so I am quite happy to eat them, and this one was delicious, but the Whelks (there were two on my plate) were a different matter, and I only managed to down one, and that with copious amounts of Chablis. To me Chablis is the wine of choice with all shell and white fish, and essential with lobster. My wife prefers Champagne. We very rarely drink either, simply because both are expensive. For more oily fish such as salmon, trout and mackerel I prefer a red wine – not too powerful otherwise it will outcompete the flavour of the fish, but there is a very extensive suitable range in most countries.

Second worst is a particular Portuguese sausage. It is an anaemic white before and after cooking because it is made only of pig fat and cornflour. It tastes every bit as bad as it sounds and looks. I admit to not being a great fan of sausages, but I quite like all the other of the vast array of Portuguese ones I have tried. As with southern Europe generally these sausages are mainly eaten raw, but the white one is cooked. I doubt if there is any wine that would make it acceptable.

Although I failed to eat the tripe on its own, I do enjoy a dish local to the immediate area where I live and very slightly further north in Oleiros and Pampilhosa. It is called maranho and uses tripe. It is similar to haggis, except that goat meat and rice are used instead of sheep and oatmeal. Presunto (Portuguese dried ham) is also included, along with the usual onions and some flavourings, with parsley often included. The bag containing the maranho is made of the goat’s stomach lining (i.e. tripe), replacing the sheep’s in a haggis. I do not eat the bag. Note: Ready made haggis as bought in butchers’ shops is bagged in synthetic skins. Recipes for maranho vary slightly from household to household, but in the immediate locality mint is included. Several species of mint grow wild here, and there is only one that is chosen for the maranho. I am no botanist and have been unable to identify it with certainty.

Just to add a bit to probably most readers’ knowledge, the four different chambers of a ruminant’s stomach – the rumen, reticulum, omasum and abomasum have different types of lining and this give rise to different styles of tripe. In many cultures only the linings of the rumen and reticulum are used for human food, and very few use the abomasum lining. The river that runs as my boundary and very close to my house is called the Tripeiro. The origin of the name is said to be because the river is so clean that people washed their animals’ tripes in it. They still do and it is still that clean. Some still do their laundry in it too. The people of Oporto are sometimes known as tripeiros, or tripe eaters, because that was all they had left to eat after they had supplied Christopher Columbus’ 1492 journey with meat. It is then possible that the river is so named because the people on its banks have always been tripe eaters too.

I am aware of a meal that two of my cousins and their mother were to have but could not. My eldest brother called to visit them one day and on the way up the garden path was met by their pet, a very old, very fat, three-legged dog, and my brother said it was running flat out. Now this dog only moved when it was absolutely necessary, and waddled with difficulty. He knew there was something not quite right. He entered the house to find the occupants sitting shocked in the kitchen/living room. The reason for this was that the old fashioned range – a fireplace and oven, were totally demolished and there were pieces of food, debris and soot all over the room walls, floor and ceiling, as well as coating the occupants. Miraculously none of them were injured. It seemed that they had intended to have a few vegetables to accompany a pie. Somehow, the instructions on cooking the pie had not been followed. It was in a tin, and the tin had been put in the oven. The lid of the tin should first have been removed.

My mother was renowned by friends and relatives as a superlative cook of “afternoon tea” dishes. Of course I could never understand the raptures of other people at our always very large Sunday afternoon gatherings (never less than a dozen people) because I had the same things for tea every day of the week. Meals at home were breakfast, lunch (the main meal of the day), tea and supper shortly before bed-time, and supper always just a snack. Father worked permanent night-shift down the pit so that he could run the smallholding during the day and needed his main meal when he was at home to eat it.

Probably mother’s best was her Girdle Scones, similar things being known as Griddle Cakes in other places. Following my usual system of giving recipes, I assume that the lady who is to make these already has some cooking knowledge. Plain flour, butter and currants in the ratio of 4:2:1; baking powder (bought as a propriety product that is a mixture of Bicarbonate of Soda, Cream of Tartar and some starch), the smallest amount of salt you are comfortable with, and enough milk to make a crumbly dough. The girdle is a flat plate of iron that is heated from underneath, either an open fire or modern means. The Australian style of barbecue that has such plates, and not these silly grilled bars of metal that others use, would be ideal. Roll out the dough to three-quarters of an inch (20mm) thick and no thicker! Cut into rounds. Butter the girdle to stop the scones sticking and cook quickly on each side, turning only once. How well done you like them is up to you, father liked his as the outsides were beginning to go black, whilst others seemed to prefer mid to dark brown. I liked the lot. Some prefer them warm and whole, others split them and butter the insides of both halves. I liked them cold and split because I could put more butter on. Strawberry jam is good – on top of the butter of course.

I have eaten in an enormous number of restaurants and hotels in quite a few countries of the world. Ownership and management of these places change through time, and chefs even more quickly, but places worthy of mention are Canberra International, Australia; Morangie House Hotel, Scotland and the Buçaco Palace Hotel, Portugal.

The Buçaco is the most recent we have visited, and I am sure the standard of the hotel will have been maintained, its own aged wines (although expensive) will still be in top class order, and the surroundings are magnificent. Napoleon’s troops suffered their first defeat in the Iberian Peninsula at the Battle of Buçaco. The Canberra International is remembered for its extensive menu, the quality of the food and the fact that the Head Waiter and Chef both went out of their way to provide for a seven year old boy who liked his food, knew what he wanted, and had what the Head Waiter said were “sophisticated tastes”. In fact it was him who suggested that the boy try a strawberry flambé and cooked it with great flair at the table. When we returned six weeks later the waiter said to him “I remember you sir.”  

Morangie House is situated in a beautiful part of Scotland not far from my favourite whisky distillery of Dalmore, and very close to my second favourite, Glenmorangie. There had recently been a fire in the kitchens when we were there and rented field kitchens were in use, but the food was still superb. The thing I remember most was that the hotel offered several of the better wines from their list as single glasses at the equivalent of the bottle price. I know most places offer wine by the glass but that is the only place where I have seen the better ones offered, and nowhere with such a wide choice. In the room was a bowl of fresh fruit, a carafe of sherry and some mints. The usual chocolate on the pillow too. Not a lot of extra cost to the hotel, and undoubtedly that cost is allowed for in the room charge, but just those little additional touches that all hotels could provide, but fail to do so.

I sometimes wonder if my wife and I are alone in enjoying our meals so much. I hear so often about people eating whilst watching TV or “eating on the go”. What a way to live, or more likely to cease living at a much younger age than necessary. Proper food is cheap, time for preparing and cooking it is minimal, enjoying eating it takes a little longer. It is possible to have a top rate meal on the table in under half an hour from entering the kitchen. Obviously you need the ingredients in the cupboards and/or refrigerator, but it really is that quick. Even urbanites would be hard pushed to pick up their car keys, go to the local takeaway and have the food on the table in less time.

Something else I have noticed in recent years is that people have stopped eating butter. On the rare occasion we have visited other people who know the way we eat, there is normally cheese and biscuits provided after dinner. At home we never have less than four cheeses nor six different biscuits. This is never reciprocated. I can live with that (provided there is a reasonable quantity of Port) but I cannot live without my butter. I sometimes just butter a piece of cheese and forego the biscuit. At other times I enjoy a piece of butter, placed under my tongue, and then draw Port through it. Delicious. People generally nowadays fail to eat enough animal fat and consume industrialised vegetable fats instead. Definitely not the way to live a long and happy life.

..... you will have to provide your own.


In truth, providing your own lighting is probably the easiest task to be performed if and when modern services fail. Various types of lights were around for a long time before gas and electricity.

At the time I last posted I was working on plans for increasing the amount of food we produce for ourselves as well as feed for the animals. We are fairly well along the route of providing for the goats (the only four-legged animals we presently have apart from the essential farm cats) but buy some compound feed and this ensures an adequate supply of all necessary vitamins and minerals, as well as providing a higher protein level than the hay and maize that has until now formed the bulk of our home production. The bought in feed is also an eventual source of additional plant nutrients once it has passed through the goats and become incorporated with their bedding. I have not previously been able to grow sufficient pulses, nor have I grown as much comfrey due to previous stock not being inclined to eat it. The rest of this blog is written on the assumption that we will not be able to purchase compound feeds from agricultural suppliers, and that we need to supply all our own feed for all livestock plus food for ourselves, and as much of our other requirements as possible.

So far as I can ascertain from agronomists and feed and fertiliser suppliers there is no known problem of any trace mineral deficiency in the local soils. If there is a deficiency this could possibly lead to sub clinical trace mineral shortages before it was noticed, but we do have some control over intake. I would rely on average analyses of feeds for calculating that we would be supplying sufficient vitamins and trace minerals in the correct ratios. There are some good sources of feed analyses on the Internet. One that covers a very wide range of feeds across most of the world is www.feedipedia.org and it is produced by the French organisations CIRAD, INRA and AFZ together with the Food and Agricultural Organisation of the United Nations. Consequently I expect the analyses to be accurate – given the limitations that analysis of a growing crop changes throughout its growth to maturity, and seasonally.

My wife and I have never come to any harm from our present diet and we do not even consider our intake of vitamins and minerals. We certainly see no need to take any “supplements”. I would expect all livestock to be reasonably productive from an adequate provision of energy and protein even if the ration was not perfectly balanced for maximum 21st century levels of production. Every farm is different, and everyone else’s requirements would be different, but hopefully by outlining what I would do on my present property it will allow others to consider what they could do on theirs.

I am taking a very long-term view – to the extent that the systems put in place might have to be continued for several decades until new technology replaces that which we have lost. At the same time I am being practical and making a feed self-sufficiency plan even if the lights do not go out. If the increasing world population is to be fed then extreme increases in the cost of animal feedstuffs can be expected, with similar rises in the cost of human food. Large rises have already happened in the last few months due to reduced grain harvests in several areas of the world during 2012. So far as possible, half the land will be in pasture and half cropped at any given time, rotating through 4 years’ pasture and 4 years’ cropping. This way the pasture phase rests the land from cropping and builds up organic matter and fertility through the grazing livestock. Hay will be cut from part of the pasture land, although the goats do not need a great deal due to being able to get out all year round unless it is raining. They do not like winter rain so stay indoors by choice when it does rain.

Cropping will be based upon growing grains and pulses for concentrated feeds. Pastures, comfrey, other forage, squashes/pumpkins and root crops will be grown for bulk and Ca:P balancing since the grains and pulses are much higher in P than Ca. It should be noted though that some roots share this reverse ratio and it is well to have a record of the analyses of those crops that can be grown to ensure the correct balance can be supplied. Maize will be the standard grain used and a wide range of both summer and winter cropping peas and beans will provide the high protein pulses. By using different seasonal ranges of pulses the harvesting period is greatly extended and less storage is required.

There is an overlap between feed for livestock and food for ourselves, since we eat many of the crops grown primarily for the stock. Amongst these crops are all the leafy brassicas, some of the pulses and squashes, plus the root crops Jerusalem artichoke, beets, swedes and turnips. I grow a red beet known as Bull’s Blood which is a very quick maturing crop ready in mid-summer and has a large root. Mangels and fodder beet are also grown, and since we are considering maximum self-sufficiency then sugar beet would replace some of these.

We may need draught animals in our proposed survival group in addition to cows for milking. High producing dairy animals are not required. The milk from traditional beef or dual-purpose breeds is just as good. I think one cow to each couple (plus children where appropriate) should suffice – staggering calving so that milk and butter are always available. Cheese making is a natural part of this plan and whey plus surplus milk, if any, is relished by pigs. Cows do not have the pulling power of equines, so a horse or large pony capable of being ridden as well as used for draught may be worthwhile. Donkeys are easily fed and the larger breeds (such as already exist in Portugal) are strong enough for both jobs too. Merino sheep are common here and provide a heavy and fine fleece. Goats may not be required if we have both cattle and sheep, so at this stage I am non-committal on the need to have them. They are more difficult to keep fenced in, and I am not alone in not liking goats’ milk except as cheese. Pigs, bees and poultry would make up the remainder of the livestock, although rabbits can be fed very cheaply too. One hen per person will provide enough eggs in its first laying year, after which it should be replaced. A heavy breed provides meat from surplus chicks and discarded hens. I eat meat or fish twice a day, but not large amounts since I enjoy vegetables and, unlike when I was younger, prefer several smaller courses of food rather than just a large main course, consequently I have an annual requirement of about 60 kilograms of meat/fish. Other people will have a different requirement, but some idea of total need is essential.

Cereals for baking would be a necessity, and based on our current bread consumption and other uses think that 100kgs of grains (mainly wheat with some rye and oats) per head is more than enough. Many of the vegetables would be taken from the livestock crops, but in addition we would grow whatever we could to suit the individual tastes of the group members. Potatoes are the first that spring to mind. I have always found it difficult to sow exactly the right quantity of seed to produce the number of plants we require, but generally aim for a slight surplus on the basis that stock will consume any we do not. Not all stock like the alliums (onions, leeks and garlic) but they will generally clear up the remnants of all vegetables we consume, and I do believe a feed of garlic every couple of months helps to control intestinal worms. My theory is that the garlic creates a hostile environment for the worms and they move as far away from it as possible down the gut until they are voided. Just a theory, and others claim it kills the worms if fed fresh or the extracted juice is used. I do not normally grow carrots specifically for stock due to the high sugar content, but have no qualms about feeding some on a regular basis.

Textiles would come partly from wool of course, with leather from the skins of sheep and cattle. Pigskin makes very fine leather too. Linseed (flax) used to be a common crop in these parts, and nettles can make fibre through the same process as flax made into linen. Cotton is probably marginal at current temperatures, but they are close to where we lived in Australia, although a few degrees short of maximum summer temperatures, and there were vast acreages of cotton grown not too far away, so it could be worth a try, especially if temperatures rise slightly as they have been doing in the few years since we moved here.

In the previous post I covered our means of providing fuel. Electrical power can be provided too, although almost certainly not to the extent I now use it (two 3-phase pumps for irrigation) but a re-arrangement of pumping requirements, using old-fashioned methods to fill some storage at the high points, and this is easier on Patrick’s property than ours, will provide some gravity fed irrigation water. The means of pumping water without electricity are so vast that they would fill a book, and I suggest anyone interested in more information does a little bit of searching on the Internet – look for things like hydraulic rams, Stirling engines, spiral pumps and windmill pumps. Heat can be provided through fires, stoves and simple water circulation pipes and radiators. Gas is also an option. Not automatic full-scale central heating perhaps, but we do not have that now. Light within the house is fairly straightforward without electricity. Beeswax candles are probably the cleanest, re-using the wax that melts and solidifies again; and even rushes dipped in oil, wax or grease can provide sufficient light in a room. Oil lamps are so easy to make too. Any fireproof container with a wick in it will suffice, but they are not as clean burning as beeswax. Some power would be useful in the buildings and it should be reasonably easy to maintain sufficient for lighting in the buildings when required.

On the same theme of providing for yourself I have found many articles relating to small-scale home-made tools and equipment on the ‘net simply by diligent searching. Much of this information is from sites in places like Indonesia, Nepal, Ethiopia, India and Pakistan. Pedal power is another area with fascinating human-powered tools and equipment. Decide first what you must have, then what you would like to have in addition, and do some research to find out how to do it. With modern knowledge I am sure it will be much easier to survive than it was a few hundred years ago.

When the lights go out..............


As I post the 21st December 2012 is about half over in Mexico where the Mayans lived, and I am confident that the world will not end today as predicted by some, but have you ever wondered what would happen to you, your family and friends if there were none of today’s electronic forms of communication, no transport due to lack of fuel, and no imports of food because of there being no transport? I have been doing a fair bit of tractor work recently, as well as many hours shelling maize and busting up olive stumps with a big hammer and steel wedges to reduce them to firewood. None of these jobs are particularly mind taxing, so thoughts just drift from one thing to another. Then I began thinking what I could do – with some help, so my mind wandered along several tracks before coming up with a few ideas of what I would like to do if that happened. Whilst it is only imaginative, I feel it is something worthy of consideration because it automatically led to thinking about what I currently produce myself, and what I currently buy, then led to considering what more I could produce so that I spend less. You can do the same.

I have not considered a sudden worldwide catastrophe where almost everyone is killed and infrastructures destroyed. There is no knowing what might or might not be available in that situation. Instead, I decided to form an outline of a possible plan for if and when the power goes off, there is no fossil fuel, and food is DIY. It is just a hypothetical situation that I hope never happens, but having an idea of what you might do cannot do any harm. To develop your own ideas on similar lines you would need to be living in a rural area, which I expect most readers of this will be, and, of course I am already part way there because of my lifestyle over many years being based on living on low income, and this would really be an enforced move further towards self-sufficiency.

The scenario includes a reasonably slow move towards the position. I was not prompted to think about it by the end of the world today predictions, but by reading an article about a TV show where people are asked to give details of their preparedness for an unforeseen event, and an internet forum thread along the same lines – both referring to the USA. It seems most people would stockpile and in fact some already have bunkers and fall-out shelters fully equipped with living accommodation, and food and water for several years. The supplies will run out at some time, even if the people survive to use them all and then they have to rely on another source of food – or die of starvation. Others are stockpiling food in a remote location, and, very frequently, excessive quantities of guns and ammunition with the attitude that they will shoot anybody who attacks them. Obviously they are expecting to be attacked – and why not? If so many people are relying on guns then they will be used. The trouble with that is that John Wayne and a couple of friends seeing off a large band of gunslingers in a film is a lot different to what would happen in real life. The enemy just needs enough firepower that can be used at a distance, especially against those (and there are many) who think they will survive best on their own. Everybody needs to sleep and a group can easily deprive an individual of sleep.

So, I decided that the US is not for me. Gun ownership in Portugal is fairly common, but not universal, and restricted in numbers and type of weapon - a shotgun and a rifle probably being the maximum owned by anybody who hunts (some will have more) but gangs of heavily armed raiders are unlikely, and in fact I would expect many family groups around about carrying on as their grandparents did. Such family groups have always been able to survive, so why not in the future? Indeed it is extremely common for the sons and daughters originally from the villages but who now live in the towns to return “home” at the weekend and help out on the property. For those not familiar with Portugal, almost all rural people live in a village that is surrounded by individually owned blocks of land known as a quinta. There is not often a house on quintas, but there is very frequently a building of some description.

The envisaged scenario would mean only a step-back in time, but with modern knowledge; and there are millions of people in the world currently living with less than I would anticipate us having. Portugal is a poor country, but relatively modernised, and many more countries are much more badly off. Indeed there are many people in other countries that would not notice any difference. Even here there are a very large number of houses without water and electricity connected so their inhabitants would not miss the power going off.

I decided I would prefer to stay where I am and bring into a group some others, including Patrick and his wife who are only five miles away and living on a similar property to us. They would continue to live there. We already share farming equipment and work together on building some items we need and cannot buy at an economic cost. Our house is an enormous 3-storey stone and concrete building that was formerly an olive mill and with several separate entrance doors into various parts of the building. It would easily split into several apartments. All doors are steel and the windows have vertical steel bars so the building is relatively secure. It is wired and plumbed throughout. Several other buildings totalling a few hundred square metres are also wired and plumbed and with lockable steel doors, therefore also reasonably secure. Some are set up for various livestock and others general storage. Included in the ex-olive mill building are a bakehouse with domed oven, a meat house, dairy and cheese store, olive storage bins, and a large wine making room and cellar.

The land totals about 16 acres, all ploughable, and has almost 500 olive trees, plus various fruit and nut trees and a productive garden area next to the house. Patrick’s property has less olive trees and not as many buildings but otherwise more or less the same. We currently have adequate machinery and the ability to repair or make more equipment.

The group comprises me, Patrick, my son and a friend who was at school with him, plus our wives and whatever children the two younger couples have when and if the worst does occur. We have, I believe, an exceptional range of knowledge and skills amongst us as well as being of above average intelligence if academic qualifications are an indication. This in itself means that the group are able to learn. The “end of the known world” has been discussed on a few occasions in a semi-jocular fashion and the ideas for long-term survival are not mine alone.

At a professional level we have a medical doctor, a veterinarian, two scientists – chemistry and physics, a teacher of cookery and needlework, a computer and electronics whiz with very good mechanics knowledge, and accountancy and administrative qualifications. Now some might question the usefulness of the more academic qualifications, but the knowledge of related science subjects makes the scientists useful in many of the things we would need to tackle, and an ability to crunch numbers or organise work sharing rotas, maintain supply records, crop rotation details etc. are also required. I have the most farming and gardening experience but everybody else is “countrified” with a combined experience in seven countries around the world. Several languages are spoken. Everybody can ride a horse and most have good shooting experience if the need arises, and wild meat is always a useful extra. The four youngsters, not blood related to each other, are keen hill climbers and walkers, capable of carrying a heavy pack for many miles.

Skills wise, we can keep our machinery going so long as we have no major parts to replace. Animal power is within our reach if all tractors fail. Many people around about now use donkeys or mules, and I have seen cows used as draught animals. The olives can supply oil for fuel, plus we have PV, generators, compressors, pumps, and the ability to make methane, ethanol and grape spirit. It is legal in Portugal to distil your own brandy, with stills and other equipment readily available, and absolutely everybody in the country has grapes, so fuel (and drink) should not be a problem. We would have birds and animals for eggs, meat, milk, cheese, butter and clothing if required, with the ability to shear, kill, skin, tan, butcher, design clothes, felt, spin, knit and sew whatever is required. I am sure weaving would not be too big a problem either. We also have experience of making mats for floor coverings. Cork for insulation is a further possibility, although not something you decide to use and then be able to grow your own supplies in a couple of decades. The cork oaks I have planted need about another 30 years to their first harvest.

Cooking and food preservation skills are excellent. The long growing season and reasonable temperatures, rarely above 35ºC and even more rarely below minus 5º, means we can grow most temperate crops, and some short-season sub tropical ones. We already produce a large range, and increasing that production would not be difficult. A river and farm ponds are useful for fish and irrigation, with boreholes for household water, although there are numerous potable springs every few miles along the highways. I need to do more planning of the crops that would be most beneficial to grow if we were totally reliant upon our own production. I have been increasing the amount of home grown stock rations each year, and have begun work on a plan to be self-sufficient in livestock feed because of recent problems of price rises and lack of availability of some products, and I shall extend this plan to cover our own needs too. I am drafting it in a form that can be altered to make it a blog, and it will be the next one after this.

Much of Portugal is still a peasant based economy so there are hundreds of thousands of people with the land, equipment and skills to survive, plus a family to assist in the work. Consequently I do not expect any large scale violence if modern ways cease and I believe the country will simply get on with life as it always has. Like my wife and myself, most of the older people have lived with limited money so they have had to fend for themselves.

Bartering is always a possibility, and although I think most rural people would have the same items, I also expect there would still be some urban life, and their skills could be bartered for some of our fuel, food and drink. There is a lot of vacant land around the country too, huge numbers of unoccupied former small farms complete with a building, olive trees and grape vines, and there is a lot of space for present townspeople to move out and start farming again. All in all, it is probably one of the countries least likely to suffer from a collapse of modern society. How would you cope?

Comfrey


In English, the word comfrey is used as the general name for Symphytum species. The same term has been in use in various languages since at least the 1st Century. Pliny, a Roman, called it conferva. This later became cumfria, then (Old French) confrie, and, with a few alternatives in between, eventually the English spelling of today. Symphytum is derived from Dioscorides, who was contemporary with Pliny, and a Greek physician. His word for comfrey has been variously reported as Syumphuo, Sumphutum, Sumphuton and no doubt other similar words. Symphytum officinale or Common Comfrey (so called because it was the common species in Britain) with white or cream to yellowish flowers also has a red to purple flowered variety S.officinale var. patens. It is totally erroneous to refer to S.officinale as “True” comfrey as some Internet sites do, since about 40 species of Symphytum have been identified. They are native to most of Europe and Western Asia and all are called comfrey in English, the norm being to use a descriptive term or place-name before the word Comfrey, e.g. Prickly Comfrey or Palestine Comfrey. Symphytums cover the range of colours from white through to yellow, and blue through purple to red. The Common Comfrey was introduced to North America at least as early as the 17th Century, Josselyn (1672) calling it comferie. Some of the other comfreys followed at later dates and some have also been taken to other parts of the “New World” and Eastern Asia.

Some current day herbalists believe that S.officinale is the preferred, or even only, species for safe medicinal use, Officinale meaning “of the (herbalist’s) shop”. They may well be correct, but historically more species have been used. S.officinale is uncommon, or absent (and other species are common) in some areas where comfrey has traditionally been used medicinally. With 18 of the species in Turkey alone, it is not surprising that Dioscorides was familiar with, and apparently used, more than one species since presumably nearby countries have at least several of the species found in Turkey. Gerard in his Herball gives an unusual use for the root juice in ale; it is “given to drinke against the paine in the back gotten by wrestling, or overuse of women”. 

Of most interest to those people wishing to use comfrey for plant food and livestock feeding are hybrids, specifically of the species Symphytum x uplandicum, a cross between S.officinale and another Symphytum and now widely known as Russian Comfrey. S. x  uplandicum is a naturally occurring hybrid, the original being found in Uppland, Sweden and not Russia. Later discovered hybrids were from Russia.  These hybrids rarely set seed, but will provide the pollen to cross with S.officinale and give yet another variation. Borage, Borago officinalis can also provide pollen to produce a hybrid. Both Borage and Comfrey are in the family Boraginaceae. When an unsorted mixture of varieties of S. x uplandicum was sent to North America from Britain in the 1950s there was a “Cold War” between the USA and Russia, so it was given the name Quaker Comfrey. Lawrence Hills was instrumental in exporting this mixture and he was the founder of the Henry Doubleday Research Association. The HDRA was named in honour of Mr Doubleday, who was a Quaker, and he had probably the first ever Russian hybrids in Britain, sent to him by the Head Gardener at the Palace of St.Petersburg.

The most common cultivar in use amongst gardeners and livestock people is S. x uplandicum ‘Bocking 14’ but some, such as myself, use ‘Bocking 4’. Together with all the other Bocking cultivars, at least 21, these were first identified by Lawrence Hills from amongst a large assortment of collections from various people and places. He called each collection a strain or mixture after the people or places where they originated. He did not breed or “develop” the cultivars as is often reported, they already existed, but nobody before Lawrence Hills had identified them as separate cultivars of the same species. In this context please note that a lot of current Internet sites replicate other sites in their supposed “information”. Lawrence Hills warned against such incorrect repetitiveness long before the Internet was invented.  He made great efforts to identify some of the highest yielders, but time and space prevented him doing long-term trials of every hopeful, so if you have a mixture there could be a world-beater amongst them.

All comfreys only actively grow from spring to autumn in temperate climates, dying down before mid-winter, and timing depending upon how “temperate” the climate is. In tropical climates they will grow year round if there is not a long dry season and in temperate areas with a long dry summer they need irrigation for high production. S.officinale sets seed that germinates very easily. So do some of the other Symphytums. Stick to the Russian hybrids if you want to control the size of your plot. Anyone buying named cuttings of a Russian comfrey hybrid, whether root or crown cuttings, also called crown sets or offsets, should find that all plants are of the same cultivar. That means the flowers will all open with exactly the same colour, and fade to the same colour, although there could be some slight variation during the phase from fully open to faded.  If the flowers are not all the same then you have a mixture, and will need to do your own work on identifying the high yielders, just as Lawrence Hills had to do.

Knowing the wide variations that Lawrence Hills found in his mixtures I collected samples of as many collections as I could find when I farmed in the North of Scotland prior to moving to Portugal, with a view to trying to find something that might outyield the Nos. 4 and 14 I already had, along with some S.officinale. I failed to find one in the collections I acquired. I did not have many years to experiment, up to about 7, but with only around 100 plants it was not difficult to spot low yielders and anything that looked promising. Nothing I had acquired was near the 4s and 14s for yield.

I operated a commercial free range egg enterprise on this farm, using mobile night shelters holding either 80 or 120 hens and the hens had free access to all the comfrey beds. They were not interested in the plants at all. This is not unusual, and if you want to offer comfrey to poultry it is best to cut and wilt it first, possibly even chaffing it. I understand this is particularly important for No.14. Poultry apparently find the higher potassium content of this cultivar distasteful when it is growing or offered freshly cut. On the other hand I have heard of people being able to feed it fresh, so it is worth a try if you want to feed it to poultry. I did not attempt wilting and chaffing because I was not interested in feeding it. I had a specially formulated layers’ ration made up for me and delivered in bulk pelletted form. The hens did pick up various tidbits every day, including some greenstuff, but being on a commercial basis, I had regulations to meet as well as endeavouring to sell particularly high quality eggs, and wanted the hens to concentrate on eating the ration I provided. Too much greenfeed can colour the albumen and give an “off” taste.

I kept meat rabbits until the increasing egg enterprise meant I had to cut back on the workload and the rabbits had almost all taken readily to most comfrey leaves they were offered. Some did not like it fresh, wilted or dry. Those that did saved me the cost of bought in hay.

I brought a couple of crown-sets of No.4 with me to Portugal because, following the advice of Lawrence Hills, this is better suited to livestock and I intended to use it primarily for this purpose, the 14 with its higher potash being preferred for plant food, although both can be used for stock; as well as in compost, as a mulch, liquid fertiliser, dug into the ground or laid in drills underneath potatoes. As it happens my land is naturally high in potash so the lower level in the No.4 is not a problem, and the amount is still substantial in any event. One of the analyses made by the HDRA showed No.4 to have 2.35% Calcium; 1.25% Phosphoric Acid (about 0.9% of the P in the N:P:K figures shown on fertiliser sacks) and 5.04% Potash. An analysis of No.14 on another occasion showed 7.09% Potash and lower Phosphorus, with an analysis of No.15 showing similar results to the No.14. Mineral content of the leaves will alter over the course of a season, and I may have my own samples analysed.

I increased the plants from crown sets but only to about 30 plants. I keep a small goat herd of up to 20 does, and they have never been particularly fond of comfrey, often pulling the leaves out of the feeders to try, and then discarding them. I tried many times each summer with only a few does and kids being interested – until this year which began with a particularly dry winter and the usual dry summer, therefore no fresh grazing and very little browse.

Most of the goats took to the comfrey by about the end of July, and my limited stocks had to be fed very sparingly. I have increased the number of plants I have and earmarked another area for a further increase in the spring in the hope that the goats will continue to readily eat comfrey. I hope they do because it makes an ideal complement to maize and beans with a reverse Ca:P ratio to them. Comfrey is higher in calcium. It is also high in protein so can at times replace the beans. I feed some grain and pulses or concentrate all year round, but more in spring and late summer when the comfrey is available and there is limited grazing, either because the fields are shut up for hay in the spring, or because of the dry Iberian summers when pastures do not grow. These two times also coincide with peak lactation of the does and the flushing period (see the Amazing Maize blog). If the goats decide not to eat the comfrey then I shall use it as a mulch around fruit trees.

Whether or not the goats do eat the comfrey I intend to trial it in the Ribeiro Grove of 180 olive trees which I finished planting earlier this year. It will be labour intensive but I believe will be worth the effort. At 6 metres spacing of the trees a comfrey plant can be placed 2m each side of the trees to give two plants per tree. The olive trees have a fairly small root area for a number of years, and not a particularly large one when mature so the comfrey and olive roots will not be competing for space in the soil. The nutrients which the comfrey removes from deep in the ground is kept in the same area under this system, so whilst the soil is being mined, concentrated minerals are returned no more than 2m away and the land does not lose them. Instead they are recycled. Harvesting the leaves and using them for any purpose elsewhere means that the comfrey land loses nutrients.

Obviously some of the nutrients will be locked up in the trees, and the olive harvest will remove some, as does any cropping between the rows, such as the maize this summer, and a current crop of beans. These nutrients need to be replaced, and since I will be fertilising for the crops, they will be. The comfrey and trees will automatically receive their share of the crops’ fertiliser since I use a broadcaster across the whole grove. The area is irrigated via overhead sprinklers and my other grove, the Estrada Grove of 299 trees planted in 2006, is irrigated through drippers, which means that the irrigation is only along the tree lines, but consequently also suitable to take comfrey plants. That is a possibility for the future, but this area is only fenced to grazing livestock standards, and wild pigs occasionally make a foray. I am sure they would destroy a comfrey crop the same as they do a maize crop, so the boundary would need to be pig proofed first.

Another means of using the comfrey would be for me to make liquid manure, simply allowing the comfrey to liquefy inside a container and draw-off the concentrated liquid fertiliser. This could then be fed through the irrigation systems. I have some filters on the lines, but anyone planning on doing this might find that additional fine filters are needed for drip irrigation systems otherwise the drippers can become blocked. The overhead sprayers would not be a problem since they would not block with small pieces of vegetation. If I do use this system, then I will have the concentrated liquid analysed.

A further alternative use that I am also considering is the use of comfrey as part of the feedstock for a small-scale biogas plant. Due to its low C:N ratio, around 10:1, it would make a good feedstock alongside vegetable waste, or a higher carbon crop grown specifically to feed it - especially the forage part of maize. The digestate from this process can be used as a replacement for compost, saving some fertiliser costs, or further used to produce ethanol. I have done a little research and whilst a household sized methane digester is cheap, and feasible on a DIY basis, I have not gone into costs of a slightly larger scale plant, and done very little work on the ethanol production stage because obviously I could not do this without first producing the digestate. My personal use of methane would be to power a generator to pump irrigation water. This means I would only need to produce methane during summer, which fortunately for me is the time when ambient temperatures are ideal for methane production. Consequently I would be using a batch process rather than an all year round constant flow digester. Batch production is cheaper and the equipment less complex although less efficient. This idea too is for some unknown date in the future, and I would work in collaboration with Patrick (see the old blog entitled A Glossary followed by a blog on Olives) since he is much more knowledgeable than me on the technical aspects.
