Right, no more faffing around. Without further ado, I’m going to describe the layout of an ‘average’ 10 hectare holding in the Peasant’s Republic of Wessex, circa 2039, as introduced in various preceding posts. The holding, remember, has 10 whole-time equivalent workers, and ten dependents (children/elders). I’m going to play around with those figures in due course, but let’s stick with them for now – so imagine 10 people doing the work implied in what I outline below. As to what energy sources they’ll have available…well, I’ll come to that when I’m ready.
Please shout out if you don’t like any of the numbers I’m about to throw around
1.The structure of the holding
First, I’m going to take out 3.5% or 3,500m2 of the land area on my 10ha holding for houses, outbuildings and tracks.
Each of the five houses on the holding gets their own 250m2 organic vegetable garden, totalling 0.125ha in all.
There’s just under 1.4ha of cropland, farmed organically, which the residents jointly tend.
There’s about 6ha of grass for grazing, comprising about 5ha of permanent pasture, a 0.5ha orchard with fruit and nut trees and grass in between for grazing (the trees may need some protection), and almost 0.5ha of temporary grass/clover ley in the cropland available for grazing.
There’s about 2.5ha of woodland.
In a real situation, I think people would grow a pretty wide range of crops, a lot of them minor ones occupying small areas. I don’t see it as my job to lay out in exhaustive detail exactly what all these crops might be, so for this exercise I’m restricting the cropping to a relatively small range of fairly obvious crops. I’m interested in any suggestions for refinements, particularly if they come with reasons as to why it’s important to include them.
In relation to crop yields, I have three sources of data. First, my own data back from the days around 2010/11 when I was young and enthusiastic and I could be bothered to keep meticulous cropping records. Second, I have data in the form of a sneak preview from my friend Rebecca Laughton’s fascinating forthcoming study of small farm productivity in the UK. And finally, I have data from my copy of the 2011/12 Organic Farm Management Handbook. If I get a few more donations to the website I might splash out on a newer version, and update the figures. In keeping with my preference to err on the side of under-estimating rather than over-estimating yields, in each case I’ve taken whichever of my three data sources reports the lowest average yield. I think the yield per hectare figures I’m assuming generally are on the low side, but I’d welcome any comments.
Other sources of data I’ve used are further referenced below.
One other point: some people like to stress the yield advantages of backyard scale, labour intensive mixed cropping and might therefore think that the yield data I’m using from commercial-scale single-crop systems underestimates the possibilities. I’ve explained here why I’m a bit sceptical about the claims made for mixed cropping. And in any case, as I’ve just said, I don’t mind underestimating a bit. Where I have made minor allowance for the benefits of small scale is in the issue of edge. I don’t go with the over-mystical enthusiasm for edge associated with the wilder shores of the permaculture movement, but look at it this way: a square 10ha field has a perimeter of 1,265m. You could sow wheat in the field while establishing around 300 apple trees around the perimeter with essentially no loss of growing space for the wheat. A cereal farmer with a large number of 10ha fields isn’t going to do that. But 10 neo-peasants living in a 10ha field probably are. So in that way we can increase the effective growing area of the field using nothing but the magic of human labour and linear planting, so long as we don’t push that logic too far…
OK, so let’s look at what’s in the shared cropland. First up, I’m going to set aside about 350m2 to grow hemp and flax in order to make clothes. Personally I prefer wearing cotton and synthetic fibres and would probably be willing to spend some of my off-farm household income on that if it wasn’t too expensive, but let’s go with the home-grown option. I’ve taken figures for hemp and flax from Simon Fairlie’s ‘Can Britain feed itself?’1 – it amounts to about 7kg of fibre per person per year.
The rest of the cropland is split into an eight course rotation, each course occupying just under 1,700m2. The rotation I envisage is as follows (though not necessarily in this chronological sequence):
1 – Grass/clover ley (available for ruminant grazing)
2 – Grass/clover ley
3 – Potatoes, split between earlies yielding 6.4 tonnes per hectare (25%) and maincrop yielding 12.7 tha-1 (75%)
4 – A short-straw spring wheat, yielding 3.5 tha-1
5 – A long-straw, traditional variety winter wheat with low fertility requirements, yielding 1.75 tha-1
6 – Legumes, split 50/50 between broad beans for the summer and drying beans for the winter (both 2.5 tha-1)
7 – Vegetables: split between cabbages (75%) yielding 35 tha-1 and swede (25%) yielding 24 tha-1.
8 – Vegetables: a third each of onions (19 tha-1), leeks (11 tha-1) and carrots (35 tha-1)
I’ve grown wheat on small scales from time to time with mixed results – the main problem being that the small-scale sowing and especially harvesting technologies I’ve had available weren’t that great. In a society with a lot of small-scale wheat cultivation, that would probably change. Wheat’s co-product, straw, would be in high demand around the holding – one reason for growing a traditional long-straw variety, as suggested by Michael under a previous post.
Yield figures for potatoes, wheat and legumes are further corrected for seed input. The other crops aren’t corrected, on the grounds that it’s fairly negligible.
In the garden, I’m projecting seven crops, though in reality there’d be more:
1 – Espalier apple on the south-facing edge: just over 3 trees on average in each of the 5 gardens, yielding 9kg of apples per tree.
2 – Tomatoes: 30 plants per garden yielding 2kg per plant
3 – Strawberries: about 80m2 yielding 6.3 tha-1
4 – Chard: about 40m2 yielding 30.5 tha-1 (cut and come again)
5 – Courgettes: about 40m2 yielding 40.8 tha-1
6 – Lettuce: about 40m2 yielding 3.3 tha-1
7 – Kale: about 40m2 yielding 35.7 tha-1
Fertility in the garden would come from compost generated from around the site. I’ll write more about fertility in another post.
In a 0.5 ha orchard, I think there would be space for:
- 56 apple trees on MM106 rootstocks, producing about 26kg per tree
- 47 pear trees on Quince A rootstocks, producing about 17kg per tree
- 58 plum trees on St Julien A rootstocks, producing about 12kg per tree
- 47 hazel bushes, producing about 3kg per tree
Yield data here is from Harry Baker’s lower estimates in his The Fruit Garden Displayed – an old one, but a good one. Hazel was a key part of the pre-agricultural British diet, and is one of the few realistic sources of non-animal dietary fat in these parts. Perhaps there’s a case for growing more? Then again, our ancestors didn’t have grey squirrels to contend with…
5.Livestock and Meat
I have little experience of dairying, so I’m a bit uncertain of these figures and would welcome any comments. But the most efficient way of getting useful human food from grass is via a dairy cow, so there will be cows on my holding. These will be more or less pure grass-fed house cows, not souped up (or at least soya and cerealed-up) champion milkers of the modern kind. They will have preferential access to the clover-rich leys on the cropland and will otherwise be part of a grazing rotation over the permanent pasture. I’m assuming 1 ha of grazing will feed a cow and her calves over the year, and yield 4,000 litres of milk, plus 90kg of meat per hectare per year from the calf (slaughtered at 2 years, and with some kept as cow replacements after 10 years). There’d probably be a need for careful pasture management (and maybe occasional reseeding?) to ensure a relatively high-productivity pasture (white clover, perennial ryegrass etc.)
There would be 3 house cows on the holding. About a fifth of their milk would be kept for direct human consumption, which works out at about 300ml per day for each of the 20 people on the holding. The rest of the milk would be turned into butter and cheese. I’m assuming about half of it will be devoted to butter, with 20 litres of milk producing 1kg of butter (I’m anxious that my neo-peasants have enough fat to eat and to cook with). And just under a third is devoted to cheese, with 8 litres of milk going into each kg of cheese. The butter and cheese-making processes give the co-products of buttermilk and whey respectively (90l of buttermilk per 100l of milk for butter, and 87l of whey per 100l of milk for cheese). A little bit of this will be eaten directly by the people on the holding, but most of it will be used to feed pigs (see below).
I’m assuming that a hectare of permanent pasture could support 6 ewes plus their lambs (and a ram, or part thereof) year round. I think that’s a pretty low estimate, but it provides a bit of extra margin for the cows. The sheep would be on just under 3 ha of the permanent pasture, and there would be about 18 ewes in all, each producing 1.5 lambs annually on average. Ewes would be culled on average at five years, with lambs raised to replace them. On the basis of those assumptions, the sheep would produce 544kg of meat (lamb and mutton) per year, plus some wool and other bits and pieces which would doubtless come in handy. Rotating them around the pasture with the cows would help to keep the worm burden down.
I’ll start with the assumption that I can raise two pigs in the woodland. I know this is cheating a bit, but I’ll have a clearing in the woodland in which I can grow some clover and fodder beet for them. They’ll also get to eat waste material from the gardens and kitchens (there’s no swill ban in the Peasant’s Republic of Wessex). This is pretty much what I do now, and I reckon I could easily raise two almost-default pigs this way. But I’m worried that my neo-peasants aren’t going to have enough easily available fat, so I’d like to raise some more pigs. If I reserve all but 5% of the buttermilk and whey from the dairy as pig food, and on the assumption that you have to put about six times more energy into a pig than you get out, I reckon I can raise another four pigs from the dairy. I think there’ll also be a bit of a surplus of potatoes and beans from the field crops, so I’m going to devote something like 650kg of the potato crop and 150kg of the bean crop to pig food, getting an extra three pigs. And that should give us about 400kg of pig meat per year altogether (I’m assuming smaller, leaner pigs at slaughter than the current commercial norm – killing out at 44kg, which was the weight of my default-raised Tamworths last year). We should be able to get a good few kilos of lard out of the pig meat (and a little more from the beef) which, together with the butter, will be our cooking fat. Having nine pigs in the woodland may trash the ground a bit, but on the basis of my current pig-keeping experiments I think it’d probably be OK – the average holding would just be raising weaners during the warmer months, which limits the damage.
(iv) Ducks and/or hens
Personally I prefer ducks to hens – better for eating slugs, the No.1 garden pest in Wessex. Though hens are better with some of the insect pests. And ducks’ waddling is less destructive of the ground than chickens’ scratching. And since I don’t have a TV or young children, ducks are also better at the slapstick humour otherwise missing from my life. But, ducks or hens, my assumptions are basically the same – I’ll have ten of them, each laying on average 285 eggs per year, and requiring about 10kg of feed a week. Half of that will come from their foraging free-range – well, not entirely free-range, but probably a lot more free-range than the ‘free-range’ products in the shops. The other half will come from the wheat. Talking of free-range, that reminds me that at some point I need to discuss fencing. But not right now.
At the end of their laying lives I guess I’d put the ducks and/or hens in the pot. But the amount of meat isn’t much to write home about, so I’ll ignore it. Meat hens/ducks of course are an option, but a less efficient one. I’m not including any here.
There’ll be five geese, to be eaten at Christmas, or solstice, or whatever Dionysian rites there are in 2039 to keep the winter blues at bay. The geese will fight it out with the cows and sheep for grazing during the year.
There’ll be bees, helping with pollination as well as providing honey, wax, propolis etc. But I don’t think there’ll be much honey, because they need it more than us and we won’t be poisoning them with sugar. So let us say we’ll have just 10kg each year to put by for a rainy day.
Fish are efficient converters of fish-food into human-food, and before we became habituated to sea-fish and salmonids, fishponds were a ubiquitous part of the farmed British landscape. I’m sure that there would be neo-peasant fish farmers in Wessex. But most fish farming systems I’ve seen are high input as well as high output and quite energy/building intensive, so I really have no idea how to make realistic estimates. Therefore I’m going to ignore farmed fish. Likewise with wild freshwater fish. I’m sure people in Wessex would fish in its lakes and rivers, though with so many people around they’d have to be careful not to fish them all out. So I’m going to leave freshwater fish as another under-exploited margin in my analysis.
Sea-fish, on the other hand, seems like a margin worth exploring, given the historic importance of fishing in Wessex, the hundreds of miles of coastline, and the nutritional excellence of wild fish. But it’s a bit tricky coming up with an estimate of sustainable catch. And perhaps also thinking about fishing technology in a potentially energy-constrained future – though, more than with most things, perhaps the sun, wind and brine of the maritime environment suggests ways that it could be done using mostly renewable inputs.
I confess that I was fairly ignorant about the UK fishing industry until I obtained a copy of the UK Sea Fisheries Statistics and achieved instant enlightenment. Did you know, for example, that 418,000 tonnes of pelagic fish were landed by UK vessels using demersal trawl/seine gear in 2014? Seriously? Well do try to keep up.
I thought long and hard about how best to convert current catch statistics into something that seemed likely to be sustainable. In the end, I plumped for the simple expedient of limiting the catch to that which is currently brought in by UK boats of under 24m, constituting a mere 25% of their total catch. Allocated out on a per capita basis that gives everyone about 2½kg of fish per year each.
My friend Paul has used a more elaborate methodology, looking at estimated sustainable fish stocks from the European Atlas of the Seas, applying it to fishery zones of the western seaboard and allocating it out accordingly to the people of Wessex. He comes up with the much larger figure of 36½kg of fish per person per year (doubtless my figures are biased towards the considerably smaller onshore fishery while his include more distant offshore fisheries). I propose in time-honoured fashion to split the difference, giving my neo-peasants 19½ kg of fish each per year. This, incidentally, is the only source of food they get from off the holding.
(viii) Meat – A Summary
The holding’s pastures drive its meat productivity, particularly through the medium of its dairy cows. So my assumption of 1 cow plus calves per hectare is key. I hope it sounds reasonable. To put it into context, in his ‘restoration agriculture’ system, Mark Shepard proposes to produce just under 20,000 litres of milk and just over 1,200kg of meat from one hectare of his Wisconsin farm2, something that elsewhere I’ve suggested seems implausibly optimisitc3. Here, I’m proposing to produce 4,000 litres of milk and 168kg of meat from one hectare of a Wessex neo-peasant farm. I guess you could call Wessex the Wisconsin of England, only with a few more people and a few less lakes. And, apparently, a lot less meat and milk.
It shouldn’t be hard to produce 15kg of fresh shiitake mushrooms on logs cut from the woodland each year.
And it shouldn’t be hard for the kids to harvest 10kg of blackberries from the woodland and hedges, along with 10kg of sea buckthorn berries that will have been strategically planted along one of the holding’s many edges. In fact, there’s huge scope for growing a lot more in the way of fruit and nuts along these edges, but I’ll leave things at that low level to create another underexploited margin.
I’m not convinced that there’s all that much scope for bushmeat from the holding. I doubt many people will be raising game birds in the Peasant’s Republic of Wessex (there’s no Duchy of Cornwall, remember), so that pretty much leaves us with deer, squirrels, rabbits and pigeons. Usually, I find it more trouble than it’s worth to go after these creatures, though sometimes either luck or fury at their crop depredations brings some of their meat to my table. Teenagers with guns around the place can help – though remember there’s 20 people in every 10 hectares, so if you’ve got a rifle make sure you aim it downwards. Anyway, I’m estimating a parsimonious 4kg of bushmeat per holding per year.
Doubtless there’s some scope for collecting wild plants and mushrooms, and for developing invertebrate farming with good input/output ratios (mussels, snails, insects etc.) But again I’m going to leave all that as an unexploited margin.
Well, there you have it. The full dope on the neo-peasant holding. In my next post I’ll plug all of that into my magic spreadsheet to reveal the nutritional consequences of the Wessex way of life.
