| In Finland, the first large-scale efforts to control nutrient loading from agriculture got under way with the introduction of the EU Agri-Environmental Program in 1995. We examined whether these efforts have decreased agricultural nutrient losses and improved the quality of receiving waters. To do so we used monitoring data on fluxes of nutrients and total suspended solids in agricultural catchments in 1990–2004 and on the water quality of agriculturally loaded rivers, lakes and estuaries in 1990–2005. No clear reduction in loading or improvement in water quality was detected. Hydrological fluctuations do not seem to have eclipsed the effects of the measures taken, since there was no systematic pattern in runoff in the period studied. The apparent... |

| The P losses from agriculture are controlled by natural characteristics, agricultural practices and national and international agricultural as well as agri-environmental policies. To reduce the P losses the measures should be targeted at the areas and activities that are responsible for the highest actual losses of bioavailable P. The response of an aquatic ecosystem to agricultural activities is a result of complex interactions between physical, chemical and biological processes. |
