Abstract:

Smith (1979) developed a general model to simulate the carbon, nitrogen, phosphorous and potassium dynamics in soils.
The following processes are simulated in the model:

rainfall and runoff
soil hydrologic balance
soil moisture
soil temperature
dynamics of carbon, nitrogen, phosphorous and potassium
fertlizer
tillage and residue management
crop type and
crop growth.
