APES, a modular model was developed in the SEAMLESS project (Van Ittersum et al., 2008)to assess, in different EU regions, the impact of farm management on crop production andenvironmental externalities. Such purpose assumes the capability of APES to simulatecropping systems in a wide range of climate, soil and crop management. The main topic ofthis study is to evaluate APES, under different stresses and management practices(temperature, water and nitrogen), to simulate crop production and nitrogen and waterdynamics. For this evaluation, APES was compared to the CropSyst (Stöckle et al., 2003)model (widely evaluated and used under different biophysical conditions and managementpractices). An explicit description of the limitations and specificities of each modellingapproach is related to the behaviour of each model in different situations.
