where is she getting her info from that she "knows what land rent goes for"? if you look at it this way, 25 bucks is only 3 bushel of beans at current prices, benas can have a yield swing of 5-10 bushels easily with one rain, and some guys leave 3 bushels behind their combine. If it where me, and no way of talking her out of raising it, I would try to tighten up my belt a bit, maybe find some better priced seed or variable rate fertilizer and seed to cut back on excess un-needed fertilizer and seed.
