Abstract: The nitrogen (N) balance provides an indication of the risk for N losses into the environment. Previous studies have shown large variation in N balance among producer maize fields in the US Corn Belt, even within the same region and year. However, little is known about the soil and management factors explaining variation in N balance and to what extent the influence of these factors on N balance occurs via grain yield, N inputs, or both.
