I just came in from drilling in 550 pounds of rye 20 pounds of turnips and 50 pounds of radishes with my Gp606nt drill. I brush hogged the plots and sprayed a few weeks ago. It was really hard to see where I had been. When I was a kid our planters had drags that flipped over and in the powdered soil it was easy to see. Much different with a no till in dead grass. Anyone use foam marker?
