Description

A substantial amount of the uncertainty and unpredictability related to corn nitrogen (N) management across the Midwest can be attributed primarily to several common risk factors: (1) environmental losses of N to water or air, (2) economic penalties from over or under applications of N, and (3) difficulties of quantifying the supply of nitrogen available from the soil, and therefore, making adjustments for in-season weather. Rainfall plays a crucial role in controlling all of these risk factors, but its effects on N management are difficult to quantify when making management decisions for unobserved or future situations.
