Description

NWHEAT is a SUCROS type of model that is able to simulate the growth of wheat under potential, water limited and nitrogen limited growing conditions. The main simulated processes are: photosynthesis, phenological development, assimilate distribution over the crop organs, soil evaporation, crop transpiration, crop's nitrogen uptake, soil water fluxes, soil organic matter decomposition, soil nitrogen mineralization and other soil nitrogen processes.
