A Steady-State Conceptual Nitrogen Model for Estimating Nitrogen Emissions from Cropped Lands
1977
Tanji, Kenneth K. | Fried, Maurice | Van De Pol, Ronald M.
Details of a conceptual nitrogen model are presented. The model is based upon the principles of mass balance and steady state. It considers both water and N flows into and out of the crop root zone. Illustrative computations are given for estimating steady-state N leaching losses from two corn (Zea mays L.) field sites and comparisons are made with measured values. This model may be applied to other crops or cropping practices.
