With potential yield losses at stake, corn growers are being urged to check nitrogen levels in their fields this summer.

Darrell Anderson, Successful Farming Radio Magazine, discussed that issue with Tom McGraw, owner of Midwest Independent Soil Samplers in Buffalo Lake, MN.

“The decisions are more important than ever,” says McGraw. “We can’t just throw on lots of nitrogen for insurance purposes because of cost and environmental issues.”

McGraw suggests using satellite imaging or aerial photography to detect signs of crop stress, such as the John Deere Agri Services OptiGro system.
