Bill Mitchell, a retired University of Delaware agronomist now living in New Hampshire, praises the nitrogen-producing qualities of hairy vetch as a no-till cover crop. After doing extensive research on hairy vetch, he believes it provides a 100-pound nitrogen credit per acre to the following crop and is suitable for corn.

Regardless of what tillage system was used, no-till consistently provided a moisture advantage over a 3-year period in the Mid-Atlantic Cropping Systems Project at Port Royal, Va.

Ron Mulford is constantly looking for ways to squeeze more profit out of an acre of ground. A switch to narrower-row crop production was the method he turned to in a push to increase no-till corn yields.
