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. date: 2003-12 type: Journal paper type: NonPeerReviewed format: application/pdf language: en identifier: /id/eprint/4635/1/4635.PDF identifier: Berntsen, Jørgen; Petersen, B.M.; Pedersen, A. and Jensen, L.S.
