Maybe the unsourced numbers on the page you linked to are plain wrong? I know, it's the first hit when you google, but let's do some more "research". I raise you a Wikipedia! https://en.wikipedia.org/wiki/Edible_protein_per_unit_area_of_land https://en.wikipedia.org/wiki/Edible_protein_per_unit_area_o... According to these numbers, soy beans produce about 16 times(!) as much protein for a given plot of land compared to beef. That's quite a difference. Thanks for the reply! Edit: I hope this doesn't sound condescending or suchalike. I'm really interested what the real numbers are, but the page you linked to (while honestly very intersting; permaculture! No-till-agriculture) is somewhat lacking in credibility. I hope we can find a tabulation that satisfies our curiosity and our purpose.
