You need to look at what you have planted around your property first. If there are larges fields of beans and corn a few small food plots arent gonna be able to compete with the big agricultural fields. What I like to do is try and find something different that the deer cant get anywhere else. Sometimes Ill plant a rape/turnip mix, sometimes biologic, sometimes forage oats, they all work great you just have to offer the deer something they really like that they cant get elswhere.
