Summary

Carbon, nitrogen and energy flows are considered as an appropriate basis to characterize farming systems and to evaluate the environmental effects. Using the model REPRO the carbon and nitrogen flows of the experimental farm “Klostergut Scheyern” have been evaluated since 1991 on the basis of complete cultivation data as well as with the help of detailed site and weather data. Thus “Scheyern” is characterised as an intensive organic farming system with a high turnover of C and N.
