The goal of timing nitrogen (N) applications to corn is to supply adequate N when the crop needs it without supplying excess that potentially can be lost, say experts at Pioneer Hi-Bred.

Because N reactions in the soil are closely linked to both temperature and moisture conditions, this goal often is hard to achieve. Applying N at multiple times, including the time of maximum crop uptake, can spread the risk of N loss and crop deficiency, improve profitability by reducing N rates and benefit the environment.
