Diffuse emission from agricultural land is a major, persistent source of nitrogen and phosphorus in surface waters. In this contribution, we present field experiments of a series of robust options to remove nitrate and phosphorus atfield drainage level. Nitrate removal was enhanced by stimulating naturally occurring denitrification by adding wood chips. The results showed that the initial removal rates were high (between 60 and 80%). Efficiency decreases in case of periodic presence of oxygen. The concentrations of phosphate in the effluent showed peaks during the first year at high temperatures and l ow waterdischarge. The emission of nitrous oxide to the surface above the drains was negligible, but was increased at the ends of the drains....
