Ecology Colloquium Series - Modeling Phosphorus Dynamics in Soils and Release to Water Systems
Rachel Rozum (Penn State)
Phosphorus (P) is a key nutrient for agricultural development; however, large amounts of agricultural P end up in water systems, leading to eutrophication. While various nutrient cycling models capture the process of topsoil P erosion, subsoil P pathways have yet to be incorporated into many models. To better inform best management practices, my research will expand the Cycles model to account for topsoil and subsoil P cycling as well as its coupling with the hydrological model PIHM.
