Due to warmer than normal conditions during March, planting started quickly and then was delayed by wet conditions around May 1. Over the entire growing season, growing degree-day accumulation was above the 30-year normal. During May, June and July, precipitation was significantly below average in southern Wisconsin, while northern Wisconsin had above average precipitation. Drought conditions continued through August and September in the southern half of Wisconsin and were also observed in the northern half of the state. Due to a dry and warm September and October, good grain drying occurred with harvest grain moisture lower than normal in all trials.
