My suggestion (once you have the fallow ground workable) would be to have half of one plot in clover/alfalfa and brassicas and For the other plot I would do half in soybeans and the other half In either corn or brassicas.
I would prefer corn but coons and bear can wreck it in a hurry. ( I trapped 1 coon and 5 skunks out of my corn field this year)
I plant 2.5-3 acres of corn and it lasts till about the middle of December.
