The soil moisture conditions and high temperature across the state during much of July and August may cause an early harvest, which means this is a good time to make soil management decisions for the upcoming season. The main driver of the fast maturity this year most likely is the heat in July coupled with lack of moisture – even though 61 percent of the state’s current top soil is adequate after the last few rain events. The current estimate of corn status in the state that corn is 86 percent dent or beyond, compared to normal of 69 percent. This means combines will start hitting the fields at least by the end of September if not earlier in some areas.
