Here is the way my favorite plot is set up. About 4 years ago when I planted my fall mixture of rye, wheat and oats I planted a little Crimson Clover and completely covered the plot with Yuchi Arrowleaf Clover. Now about the end of January the clover starts coming up as the cereal grain is phasing out for the year. Right now the clover is about 6 inches high, just right for a supplement feed as the bucks will soon be sheding their antlers and the deer are coming off of winter. I don't mow the clover, and by September it will be waist high (I know I probably should mow) and in the fall it gets disc in when I plant again (I planted Buck Forage Oats there the last two years). I think the clover helps build the soil up.
