http://orgprints.org/4635/ Simulating leaching losses following incorporation of grass and grass-clover leys Dynamic simulation models can be useful tools for predicting the residual effect of leys, but only if they have been calibrated and validated appropriately for this particular situation. The BIOMOD project has aimed at expanding, calibrating and validating two Danish dynamic simulation models, namely FASSET and Daisy, for a range of crop rotational situations occurring in organic farming. Here we report on the calibration results for an extensive experiment with residual effect and nitrate leaching following grass-clover leys. Berntsen, Jørgen Petersen, B.M. Pedersen, A.
