A Steady-State Conceptual Nitrogen Model for Estimating Nitrogen Emissions from Cropped Lands1
- Kenneth K. Tanji,

- Ronald M. Van De Pol2
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.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
