An Alternative for Advection–Dispersion in Structured Soil: Predicting the Transport of Dissolved Phosphorus Using the Convective–Preferential Equation

Accurate prediction of dissolved phosphorus (P) transport to groundwater, and especially to drain tiles, is a major challenge, particularly in structured soils where preferential flow dominates subsurface hydrology. Existing vadose zone models rely on advection–dispersion formulations that insufficiently represent macr...
