File Name : Efficiency of mitigation measures targeting nutrient losses from agricultural drainage systems: a review. Carstensen et al. (2020), 18 pgs.

This paper reviews the removal efficiency of five different measures addressing nitrate and phosphorus pollution in agricultural catchments in 11 countries worldwide: (i) free water surface constructed wetlands, (ii) denitrifying bioreactors, (iii) controlled drainage, (iv) saturated buffer zones and (v) integrated buffer zones. Metanalyses showed that all five measures reduced nitrate loading of polluted waters and often acted as sinks for phosphorus. Importantly, there was large variation in the performance of the measures which are linked to differences in design, catchment runoff characteristics and hydrology.
