$this->bbcode_second_pass_quote('mos6507', '')$this->bbcode_second_pass_quote('hillsidedigger', 'I')n a post-oil world, if America were to revert to be a nation of farmers, there would only be enough room for maybe 80 million people. That's an average of 40 acres of crop and pasture land for each family of 4 with a little excess possibly being produced which might allow some to practice the 'higher arts' in towns and small cities.
A nation of farmers eating a traditional carnivorous western diet. Diet is going to be an early casualty of peak oil unless we would rather go straight to zompocalypse.
Actually, I am thinking 40 acres for a family of 4 would be needed (in a Post-Oil setting) to provide a low-meat (not much of it wild game), mostly fruit, vegetable, nut and grain diet with some dairy food.
Why 10 acres per person? Well, by the time you find 800 million acres of farmland in the United States, a lot of it is kind of dry and marginal. As well, as pointed out in yesterday's "corn" thread, a sustainable agriculture routine reguires taking biomass from a large area to temporarily buildup a small area for farming. Also, only a small portion of each person's 10 acres would be in active production in a given year with the rest replenishing while lying fallow or growing up into trees or tall grass for awhile.

I think that using compost derived from waste (high in nitrogen & other stuff) can be used as fertilizer and create a closed system. A well-engineered system with minimal runoff should draw that figure down a lot... We need to create more closed-loops.
Even in the 1900s, corn yield per acre was like 20 bushels or such... a diversified farming (mostly vegetarian) using techinques back then should be able to support 2 people per acre. I would think with the greater understanding of soil, environment and nutrients & how everything hooks together, one could great improve upon that, better approaches & techinques ala "One Straw Revolution".
The technique I am experimenting with corn this year is a variation on the Three Sisters Method, growing 6 corn in a circle on a mound. 6 Climbing beans & peas use the corn as a pole, and squash is planted further out on mound, and spreads out between mounds to keep weeds down. Clustered on the small mounds is purslane, to prevent erosion (and also provide a non-fish source of Omega-3 fatty acids). Some erosion due to rain, etc will occur anyway but the worst of the work will be done as each mound is created and the clay soil remediated.
I am going to experiment with rotations involving potatoes and bush beans (which I have growing in another area) growing on mounds also, which I may just swap for corn/beans/squash.
The vegetable gardens are moderately elevated beds, and so far weeding has not been a huge issue. One 64-square foot bed is has about 20 asparagus, 2 tomato plants, 10 basil plants, and hundreds of carrots, beets, and radishes. So far, of the 10 areas reserved for beds, I've found the time to soil-improve & cultivate 4 (2 of 3 asparagus/tomato beds, 1 herb bed, 1 of 3 potato/bushbean/horseradish beds, and 0 of 3 --soon to change -- cabbage/broccoli/rhubarb/hyssop beds)...
They are like a keyhole shape vaguely; this shows the rough arrangement I'm constructing:

$this->bbcode_second_pass_quote('mos6507', 'T')he age of conestoga wagons heading out west is long gone. We're going to have to throw out the book on traditional concepts and just do whatever works.
Whatever works is likely to be quite traditional, just maybe outside our recent cultural norms. Tell a Chinese or Thai peasant that a family of four needs forty acres of land in order to survive, he'd think you were either an idiot or a con artist trying to steal his land.
If you look at a growing space in terms of the amount of calories needed to be grown; and then select your crops to produce CALORIES and forget this broccoli, lettuce, and tomato fetish we seem to have; you'll note something interesting. First, backyard gardens, or shared urban garden space are useless; and second, very large fields are complete overcompensation and useful only in the sense of a commercial venture. That 2-4 acre piece of land that seems both too large, or too small; is EXACTLY the right size. Our perception that it is the wrong size isn't the result of spreadsheets, calculators, and known science; it is from cultural expectation. A backyard tomato garden is OK culturally; a large farm with hundreds (or even thousands) of acres in commercial production is OK culturally. Growing enough corn, rice, beans, and peas to get a couple hundred bushels/yr of high calorie produce... thats what those bad ole redneck hicks do! Can't have that!
Yes, we are. As we are.
And so shall we remain; Until the end.

+1
I do have SOME fruit, nuts, broccoli, letttuce & tomato but for nutrition & balance... the bulk of square footage is dedicated to corn, beans, potatoes, quinoa, amaranth (and possibly wheat) -- can't grow rice though in Maryland, not long enough of growing season...
About an acre is wooded, so I have firewood source...

Give it a few years and you'll be growing coffee there.

I have considered that possibility (well not coffee)...
I think GW may push Maryland from zone 7 into zone 8. (which means I could grow tea, peanuts and cotton and overwinter jiaogulan outside)
