Computer Modeling of Nitrogen Transformations in Soils
1974
Mehran, Mohsen | Tanji, Kenneth K.
A nitrogen-transformation model was formulated for simultaneous computation of various N transformations: nitrification, denitrification, mineralization, immobilization, ion exchange, and plant uptake. These processes were assumed to obey first-order kinetics. Differential equations that describe the above processes are solved simultaneously by using the 4th-order Runge-Kutta method and the Adams-Bashforth-Moulton predictor-corrector equations. The computer model was tested against data reported from several incubation studies. This model could be linked to a transport model to predict the temporal and spatial distribution of various N species in soil profiles.
