Temperature Tracking: Dickey County Agricultural Improvement Association, NDSU Extension Service Dickey County and Ducks Unlimted are tracking soil temperatures in several scenarios in no-till corn. The group is following temperatures of a conventional tilled, strip till and no-till fields that are planted to corn. The soil probes are place at seeding depth of about 2 inches. The temperature are being logged by a Watchdog monitor every hour.
