Sensitivity analysis, calibration and validation of EPIC for modelling soil phosphorus dynamics in Swiss agro-ecosystems
We modelled long term phosphorus (P) change in agricultural soils with EPIC. The model was calibrated and validated for eighteen Swiss soil monitoring sites. Soil P sorption and bioturbation were the most influential processes. Bioturbation depth estimates were related to subsoil water-logging.
