I've planted a similar plot for the last 5 years. I would imagine your wheat is dying off now and has seed heads. I plant 3 acres every year with a mix of Forage Oats, Rye, Winter Wheat, Austrailian Peas with Red and White clover. I plant anywhere between the last week in July and the first week of Sept. By November you will have a lush greenfield that will last through the winter. I have deer pawing the snow to get to the greens. By March, it looks like a dirt field, it will pop back up through turkey season. I mow one time Memorial Day weekend and burn it down by the end of July and replant. The deer and turkey love it. I got this of the Quality Deer Management fourm, it was a professor from the University of Iowa, that posted.
