Late-Season Weather Adds Uncertainty to Midwest Corn and Soybeans

Weather remains a concern for U.S. corn and soybean producers as harvest begins following a growing season marked by periods of excessive rainfall and extreme heat. Flooding during August damaged crops in portions of the Midwest after some areas received more than 12 inches of rain. Farm Progress reported the storms caused flooding and lodged crops, creating uncertainty about final corn and soybean yields. Those problems are becoming increasingly important as combines begin moving into fields. USDA's latest Crop Progress report showed the nation's corn harvest reached 5% by Sept. 6, ahead of the five-year average. At the same time, the national corn condition rating fell to its lowest level of the season. Soybean development remains ahead of its normal pace, potentially allowing harvest to accelerate quickly if weather cooperates. The combination of heat, flooding and deteriorating crop ratings has increased uncertainty about final yields. More definitive estimates are expected when USDA releases updated production forecasts Friday.
