I actually have no idea what they're growing.

> For example, you obviously don’t plant alfalfa in a field that is waterlogged every spring. Source: https://extension.umaine.edu/publications/2272e/ Concern: There's a river behind it. Where that field ends, pretty much almost exactly, there's an embankment and it drops immediately to a river that floods basically every year, sometimes quite spectacularly. And, 'cause this is the Internet and text doesn't convey things very well, I'll also add that I'm in *no* way calling you wrong. I'm simply giving you more information in hopes that you can solve the mystery, assuming you're actually curious. I'm merely pointing this out for your consideration. I don't know and this is (strangely enough) not my domain. Until recently, my only crops were trees and blueberries. They kinda take care of themselves! ;-)
