They sell a tape, kind of like marking ribbon, that has a scent on it that the deer fear. You just wrap it around the field like a fence and supposedly it works pretty good. I think ive seen it advertised by buckmasters before. If i find it i'll let you know. Fencing a field off from deer is pretty tricky. Electric fences work after they run through it about three times and tear it to heck and back, barbed wire is a joke, anything under seven feet high is useless. So at that you have very few choices but the stinky tape.
One thing that might work being from the south is planting turnips with rye or wheat, they will browse the rye and wheat heavily but they generally dont eat the turnips until after the first frost, but it doesnt take them long to eat the turnips up after that first frost. Ive had them to eat a half acre of large healthy turnips over night.
