When heavy rains lead to flooding and standing water in fields, these resources can aid in assessment of crop damage and help inform decision-making for the remainder of the season.
Ponding or flooding of fields affects corn differently at different stages, depending on the duration of flooding and other factors. Growers should assess the potential for nitrogen loss and increase scouting for corn disease in these fields.
Soybean plants are generally able to withstand a fair amount of flooding in the short term; however, diseases favored by wet conditions may become a problem for the rest of the season. Research shows the length of time the soil is wet and the type of soil will affect plant injury and survival.
With heavy rains, private drinking water wells can become contaminated from pollutants in the flood water or surface water runoff. Learn what steps you can take to ensure a safe drinking water supply for your family.
