Thousands of Minnesota crop acres succumb to stresses from excess water each year. This typically occurs in small, low-lying areas of fields that "drown out" frequently.

This article discusses agronomic and disease risks for corn and soybean exposed to prolonged periods of high soil moisture and cool temperatures.
