Trade-offs in soil fertility management on arable farms

Our model calculations suggest that trade-offs between C inputs and emissions of greenhouse gases (notably N2O) or other pollutants (NO3, NH3) can be substantial. Due to the many data from a large variety of sources incorporated in the model, the trade-offs are uncertain. Our model-based explorations provide insight in soil carbon sequestration options and their limitations vis-a-vis other objectives.
