We developed extensions (DrainP) for the Soil and Water Assessment Tool version 2012 (SWAT2012) to simulate leaching of dissolved reactive phosphorus (DRP) throughout soils with the Langmuir isotherm, and the subsequent transport from tile drains to streams. The DrainP module was evaluated for two small tile-drained fields and the River Odense catchment (486 km 2) in Denmark. DrainP not only simulated well monthly DRP yields in the tile-drained fields but also improved the overall catchment DRP yields, and provided new insights into the source allocation of DRP at the catchment scale. The simulated soil total phosphorus (TP) accumulation in the tillage layer fell within the range of measurements.
