Last week I flail mowed some of the cover crops. They had grown quite high and thick. Some of it was so woody, that it took two passes over to properly ground up the stalks. It was full of insects, who were not happy with me, but I did not see as many rodents or snakes as I had expected. The cover crops have done their job in maintaining soil structure and cycling nutrients to provide for the next group of crop to come after them.
