The effort of analysing the N cycle on grassland dairy farms can be considerably reduced by introducing simulation models. Using the GRASFARM model, the grassland based milk production and related feed concentrate consumption and N import for a given production level was simulated on 35 farms. Results support previous experimental findings on the interactions between forage quality, forage conversion into milk as well as feed concentrate and related N input. Moreover, the model provides a precise basis of the internal N flow and enables systematic testing of scenarios with changing farm specifications.
