Mitigation measures for phosphorus and nitrogen under changing climate: conflicts and synergies
Nutrient concentrations, loads and stoichiometry (i.e., N:P ratio) in agricultural runoff affect the quality of surface waters. In Norway, the reduction of nutrient runoff is challenged by the sloped landscape, variable weather and changing climate with an increasing number of extreme hydrological events. Mitigation measures for reducing nutrient losses are pressingly needed but they do not always work simultaneously or equally for both N and P, due to the differences in their agronomic and biogeochemical characteristics and dominant transport pathways.
