Prediction of nitrogen and phosphorus leaching to groundwater and surface waters; process descriptions of the animo4.0 model

Research output: Book/ReportReportAcademic

Abstract

The fertilization reduction policy intended to pursue environmental objects and regional water management strategies to meet Water Framework Directive objectives justify a thorough evaluation of the effectiveness of measures and reconnaissance of adverse impacts. The model aims at the evaluation and prediction of nutrient leaching to groundwater and surface water systems under the influence of fertilization, land use and land management, water management and soil properties. Since the release of animo version 3.5 some new model formulations have been implemented regarding the influence of soil moisture content on mineralization and denitrification. Also the input of daily nutrient uptake rates as simulation results of external crop models is facilitated. A concise description is presented of the process descriptions as have been implemented in version 4.0 of the animo model
