CropSyst specifics
The model is written in C++ using an object
oriented programming approach.
The following processes are simulated:
- Soil water budget including:
water input,
canopy and residue interception,
runoff,
infiltration,
redistributioin,
soil and residue evaporation,
transpiration,
deep percolation,
- Nitrogen budget including: Nitrate and Ammonium transformations
(Net mineralization from organic matter and fresh straw and/or
manure residues, nitrification and denitrification),
Nitrogen transport, leaching and uptake,
- Crop growth is calculated based on radiation availability, temperature, water and N supply;
and is expressed in terms of aboveground root biomass accumulation, leaf area and root depth and
density development.
- Crop phenological development is calculated as a function of physiological time based on
thermal time accumulation corrected by vernalization and photoperiod effects.
