By farming, I'm referring to land which is planted/harvested, typically row crops like Wheat, Corn (maize), or hay (alfalfa). From doing a bit of reading on things like http://talk.newagtalk.com/forums/thread-view.asp?tid=5707&DisplayType=nested&setCookie=1 http://talk.newagtalk.com/forums/thread-view.asp?tid=5707&Di..., I'm guessing the practical limit is the speed/capability of a combine, and the length of the harvest season. It sounds like 100 acres/day is a limit, and harvest season can (typically) stretch from mid-september to end of october - or around 45 days. So, full out, presuming you use your own equipment, the largest "family" farm that can sustain a single annual harvest would be around 4500 acres.
