create a N model ensemble of at least 4 process-based models (DayCent, LDNDC, Daisy, Candy), model within-field N-fluxes (e.g., N2O-losses, NO3-leaching, N-mineralization) for optimized N-fertilisation rates and N loss predicitions, integration and testing of the model ensemble into a database driven cloud architecture, upscale the modelled N-fluxes across European pedo-climatic zones, support monitoring, reporting and verification of greenhouse gas emissions and mitigation efforts, support reduction in model uncertainties associated with the estimates of the full N budget at the European continental scale and improve knowledge on the mechanisms governing N translocation, publication and presentation of research results
