I'm from alot futher south than you are, North Arkansas, but for fall and late season I would go with a cereal grain like winter rye or buck forage oats mixed with rape turnips and some clover in there. It sounds like your acreage is gonna be plenty big enough to handle quite a bit of deer traffic on it. There are a ton of different seeds out there to plant these days, but I just mix my own its much cheaper that way. I do buy the buck forage oats because they are cold tolerant, I have planted seed oats and bobs oats but they turned yellow after a hard freeze and deer quit eating them. Like you said make sure you get that soil test done.
