According to University of Kentucky Ag Extension, the amount of nitrogen lost to heavy rains depends on several factors, with the major one being the form of nitrogen applied. Corn planted in early May under less than ideal conditions or pounded by rain is just coming up, and planting progress may have been slowed by recent precipitation, though weed emergence continues despite wet field conditions.

Why it matters

Nitrogen loss due to heavy rainfall can have significant impacts on crop yields and profitability for corn farmers. Understanding the factors that contribute to nitrogen loss, such as the form of nitrogen applied, is crucial for developing strategies to mitigate these losses and optimize nutrient management practices.
