We found that the continuous simulation of multi-year crop rotations yielded results of slightly higherquality compared to the simulation of single years and single crops. Intermediate crops (oilseed radishand grass vegetation) were simulated less accurately than main crops (cereals). The majority of modelsperformed better for the treatments of increased CO2and nitrogen fertilisation than for irrigation andsoil-related treatments. The yield simulation of the multi-model ensemble reduced the error comparedto single-model simulations.
