Go to wildlife group website. It shows a diagram of a 5 acre food plot with all kind of fruit tree's,acorn tree's, and honeysuckle planted around the edge with a 1 acre plot in the middle. All the tree's are grafted so they put out within 2-3 years. If you don't want to do that then I would plant 15 rows of corn around it and plant the middle with RR soybeans( forage type). In fall, over seed with a mix of cereal grains,clover, and brassica's.
