The article presents a study on the characterization of phosphorus (P) sources in catchment basins. The importance of P sources identification is said to be crucial in preventing eutrophication that is primarily caused by agriculture-related activities. This study on watersheds analyzed samples of soil, stream, and various storm runoff sites such as field surface runoff and farm yards. The P concentration on streams and the mobilization of dissolved P are estimated using the environmental soil test to determine the potential for sediment and P transfer in runoff from agricultural land (DESPRAL). It concludes that Great Britain's Environmental Agency needs more than the England Catchment Sensitive Farming Delivery Initiative (ECSFDI) program to achieve good water quality in England.
