I guess I see summer foods as things like soybeans, clovers, alfalfa, (I guess almost any of the legumes) and buckwheat. Fall/winter forage typically planted for food plots would include corn, brassicas, sugar beets and cereal grains - assuming you can keep the deer from hammering them before they mature (except the grains).
I have had success getting soybeans, corn and even sugar beets to maturity here when the deer numbers were down but now that they have rebounded, I almost need to E-Fence these to get them past the deer.
I know the reality of it is either plant more food, eliminate more of the mouths that eat it or a combination of the two. As Jeff Sturgis says, you can either increase or decrease your deer numbers by either planting or not planting summer foods. When antlerless permits are limited as they have been in recent years, my options are more favorable if I reduce summer food.
Oh how I wish we had the same problem as Maxi.
