RE: Northern MN foodplots
How acidic? How dry is the soil in the summer? Oats can tolerate a pH of 5. They are also well suited to cool summers in northern MN. Rye would also do OK to a pH of 5, and provide a fresh green food source in the fall. You could try to lime the soil, sand takes less lime to raise the pH than finer textured soils. If you can raise the pH to near 6, clover, short day corn, soybeans, and turnips are possible (if the soilisn't drought prone in the summer).
