You can overseed into corn at last cultivation or later (consider adding 5 to 10 pounds of red or white clover with it) or plant right after corn silage harvest. wheat, oats, annual ryegrass, etc.). A high N user, ryegrass can capture leftover N and reduce nitrate leaching over winter. It tends to outcompete legumes in the South, although low N fertility favors the legume.
