I'd be doubling/tripling up on advice if I chime in. Jager and IB both have given sound advice. I'm personally done messing with tubers and big leafy greens. I've grown some majestic turnips, radishes and brassicas in my day and the deer would rather shit in them than eat them. Any time I have planted a clover/chicory blend and/or an oat/rye blend, I have had good success. Given the amount of ground you have, I would be experimenting with just about everything for a year or two if you see this as a long term project. I'd have one plot of everything and just see what happens. Corn and beans are a given, bet location and rotation will also influence the hunting, so there's that learning curve too. I will be adding an orchard to our place in the spring to diversify our offerings and you have several places for some well positions soft mast trees!
