This is interesting, to say the least, and bears out what many of us are discovering and know.... that healthy soil and organic methods
*can* provide more food than "they" say is possible.Another section talks about the nutrient density and makeup of organic compared to factory farmed food.
Biotic means organic, in this article.
Posted to aus.gardens also as David was asking about perma/polyculture and sustainability recently, and because those of you in Oz seem to be a bit ahead of us here in the US........in regard to this matter, at least. ;-)

Another Agriculture is Possible
Many well-substantiated studies show that intensive biotic polyculture
-- that is, the cultivation of many species of food plants in a small footprint, using biotic soil amendments and nutrient recycling -- produces far more food per hectare than factory farming; uses far less water; and builds, rather than destroying, topsoil.
Although more human ingenuity, care, and attention are required, the adoption of permaculture principles and techniques reduces the drudgery of food production considerably; the permaculturist is assisting food to grow rather than forcing it to grow (or more hubristically, "growing" it), which is much less work all round than our cartoon cultural memory of dawn-to-dusk backbreaking peasant labor (which became backbreaking to pay "tribute" and debts to people with weapons and ledgers, not survive).
What intensive biotic polyculture does not do is maximise money profits, minimise labour inputs, or facilitate large-scale extractive cash-cropping.
For these reasons -- not for any failure to produce food for eating -- it is derided by industrial agribiz "experts" as impractical, inefficient, inadequate, etc. In fact, poly/permaculture's abundant success in producing food for eating is one of the things that makes it a frightening prospect for those who control people by controlling people's access to food.
What they don't want us to know is that it works. Eisenia hortensis -- the European nightcrawler (earthworm) -- under ideal worm-farming (vermiculture) conditions double their volume through reproduction every 90 days. Each individual worm can eat approximately half its body weight each day. A pound of E. hortensis, then, can consume a half-pound of non-oily, vegetable kitchen scraps each day. The majority of that mass is excreted as an extremely high quality compost, with a bit of fluid (worm tea) left over (considered by many to be the organic uber-fertilizer). So, potentially, one pound of worms can convert around 180 pounds of kitchen scraps each year into the highest quality organic soil additive. Every five pounds of worm-castings can convert one-square surface-foot of soil into a super-producer for a four months. So one pound of worms can sustain 12 square surface-feet of garden throughout the year for the highest levels of productivity.
My own [Stan's] anecdotal evidence, without using worm castings but using simply composting mulch on organic compost over non-compacted soil, is that in 12 square surface-feet, one can grow three species of food, with six plants each... producing okra, tomatoes, cucumbers, peppers, peas, bush beans, etc. Mixing them, and adding a couple of marigolds and aromatics (like mint or parilla) seems to keep the little critters from taking more than their share. Last summer I had one cucumber vine that produced around 50 mature cucumbers, totalling well over 20 pounds of food, for around three months. By rotating seasonals, it is easily conceivable to take a 12 square-foot plot in a temperate zone and raise 100 pounds of food a year... being very conservative. Neither Syngenta, nor Cargill, nor Archer-Daniels-Midland want you to know this.
They want to sell you mass-produced food, for money... which you have to work for. Let us not forget that Enclosure (forcing people off the land, or separating them from their land) was the method used to compel people into the monetized industrial economy in the first place. A
12-foot garden bed is three-feet by four-feet. How many of these can you build on a half an acre? The key is always in the design.
