Soil Temperatures and Accumulated GDD

Average 2 inch soil temperatures and accumulated Growing Degrees Days (GDD) from select OARDC Weather Station locations are shown. Based on current accumulated GDD (Table 1) we would expect corn April 12 planting prior to April 30 to be emerged or emerging soon.

Table 1. Weekly and Accumulated GDD values since April 12 from select OARDC weather locations. Corn emergence typically occurs between 100 and 120 GDD accumulation.
