Measuring and modelling greenhouse gas emissions and nitrate leaching of raw material crop rotations (MASTER)

Mitigation measures to reduce nitrous oxide emissions in raw material crop rotations can affect soil carbon stocks. Under certain conditions nitrous oxide reduction can be compensated by decreasing soil carbon stocks. This relation is not yet investigated in detail. • In this project, 2 field experiments were conducted to investigate the effect of raw material crop rotations and mitigation measures on nitrous oxide emission and soil carbon sequestration • The biogeochemical model MONICA was calibrated and validated using the data from these and other experiments • Scenarios with the calibrated model provide information on the effects of management measures, site conditions and climate scenarios on nitrous oxide emissions and soil carbon changes for the soil climate regions of Germany
