Yes, I'm sure wine grapes would have to be among the >$1400/acre net crops. As for the Soviet example, don't you think that's more likely to be telling us something about private vs collectivized farms, rather than something about large vs small farms? I'm sure there must be data out there somewhere on the efficiency of large vs small farms. Hell, I'm sure there are people who spend their lives studying that kind of thing. Presumably there's some kind of complex productivity vs size curve which varies depending on what crop you're raising (as well as a bunch of other variables) and I'm sure if I went to hang out in the agricultural economics department for a while I could find out far more than I ever wanted to know about it.
