This particular field I was converting to red clover for one season before I go back to double cropping. So I will just mow it in the spring.
One of the big advantages of the south is how easy it is to double crop. I have planted regular soy beans in early May. By Sept. they have gone to seed and dead. I drill the fall crop into the brown beans and also get a slight flush of beans mashed in by the drill.
However I am now changing my summer crop to a combo of sunn hemp, beans, peas, sunflower, and buckwheat. Incredible production, impressive soil impact, and the deer literally live in the field once the hemp gets about 6' tall. It crimps beautifully in late Sept. or early October and then transition to rye, crimson, radishes and maybe a few turnips.
