Cool. But I wonder about calories per acre, and if there is a way to account for necessary crop rotation and soil depletion.

grabbed calorie info from Wolfram Alpha: https://docs.google.com/spreadsheets/d/1Z7ROa1oI7H4jQMH1j5cs...

IIRC, crop rotation and soil depletion has a few more variables to account for-- soil type, current nutrients, what you are/aren't willing to fertilize with.

Potatoes for example should need 220 lbs nitrogen/yr [1] and soybeans or peanuts should be able to put that back after a year [2].

A couple additional data points I'd be interested in for both data sets:

1. Average Food Grade. LB that is edible is not the same as LB that could sell on supermarket shelves, unfortunately. :-/

2. Labor / Acre. Agriculture employs less than 2% of the workforce, I doubt this can go up without major economic problems.
