Abstract:

Processes of crop growth and water movement: Crop processes when there is adequate water and nutrients and no pest problems. Crop growth in optimal conditions and water-limited conditions for a range of crop types and weather variables. Water balance for well drained and partially saturated soils.

Purpose of the model:

Model parentage: SUCROS*.
