Planting Guidance Chart for 36.135°N -77.177 °E
Based on Today's Date
Corn germination is based on an accumulation of at least 40-50 GDDs over the next 4-5 days (of the current date, not the planting date). This table shows the predicted accumulation of GDDs over the next 5 days, starting with each date.
