Model description

As a component of the integrative Global Change decision support system DANUBIA, a process-based crop growth model was developed by combining the models GECROS and CERES. The object-oriented, generic model comprises sugar beet, spring barley, maize, winter wheat and potato. The modelled processes are valid for all crops and mainly comprise phenological development, photosynthesis, transpiration, respiration, nitrogen demand, root growth, soil layer-specific water and nitrogen uptake, allocation of carbon and nitrogen as well as leaf area development and senescence.
