> My experience (over decades) is I couldn't sustain my family for a year on a 1-acre garden plot even if I had the time to work it intensively and used nothing but recycled organic byproduct (compost and, uh, other stuff) as fertilizer.
I find this surprising. I help run an Atlanta-area non-profit that has a ~1 acre organic farm that donates everything it produces. For the year 2020 we have already donated 3120 lb / 1415 kg of food.
We're not trying to produce a nutritionally complete output on the farm, but that's still ~70 lb / 31.7 kg of food a week on average.
