Corn Nitrogen Rate Calculator

The Corn Nitrogen Rate Calculator is an interactive computerized decision aid designed to help growers obtain a profit-maximizing nitrogen rate recommendation. The calculator reports the profit-maximizing nitrogen rate, and allows users to adjust corn and nitrogen prices with easy point and click operation. Data used in developing the calculator are from corn nitrogen response trials conducted in West and Middle Tennessee. The calculator can currently be used to predict a profitable nitrogen rate for productive nonirrigated and irrigated fields. Response functions for less productive soils and for corn planted after specific rotational crops will be included as we accumulate the data.
