To achieve a good state of aquatic environments, reducing the agricultural phosphorus runoff is needed. However, the recent environmental protection policies do not necessarily take into account the different forms of phosphorus nor the runoff of phosphorus-binding substances. In addition, the effect of chemical qualities of water on the slow desorption of particular phosphorus is poorly understood. This study aims to answer whether phosphorus-driven eutrophication can be managed with one all-round solution, or should the solution follow the specific qualities of the aquatic systems and their runoff areas.
