Sounds similar to the areas we hunt in Alabama. We plant a lot of food plots (about 60) and have good results with a mixture of rye, wheat and oats that we broadcast mixed with fertilizer. Try to plant before the end of Sept. Do a soil sample prior to planting and apply lime as needed. It won't help much this winter, but will pay off later. Next spring is harder to suggest. Soybeans and iron clay peas will probably be eat up before they have time to get established.
