Abstract:
The Nitrogen Movement in Soil Model is a compartmentalized simulation model for
the movement of nitrogen in soil under different water budgets, irrigation
applications, and nitrogen applications. It provides output information on the
amount and concentration of nitrogen in deep percolation.
