One strategy to reduce the risk of N loss is to apply N fertilizer in amounts and at timings that closely match the water and N uptake pattern of corn. This article looks at results from a 49 site‐year study across eight U.S. Midwestern states to provide examples of the influence of soil properties and weather on the effectiveness of split vs. single at‐planting N applications.
