How much acreage out of the 800 acres is in ag production and what is being planted? timber? thick bedding cover?
Layout of the land, pinch points, natural funnels play a key figure in determining food plot location as well. But for a quick answer I would say 1 acre of perennials (clovers and chicory) 1 acre of a fall mix ( brassicas, winter rye grain, winter hardy oats, winter wheat). These would pretty much cover you year round and have different times of attraction.
