Abstract:
The model simulates the growth and development of a rapeseed (canola) crop, in relation to soil nitrogen and water status, at the field scale. It operates on a daily time step and comprises 3 main modules: - crop growth (including C assimilation, distribution within the plant, root elongation, N demand). - soil CN turnover (mineralization, immobilization, nitrification, denitrification). - heat, water and nitrate transfer in the soil profile (one-dimensional scheme). Purpose of the model:
Model parentage: CERES-N Maize (1986) and NCSOIL*.
