| الوصف: | Assessment of diffuse nitrogen pollution in the Dovinė watershed is performed by analysing agricultural activity in the Dovinė watershed and applying nitrogen leaching coefficients determined in the watershed analogues where comprehensive monitoring is performed. In the Dovinė watershed, the determined total nitrogen load makes up 473.8 tonnes per year. Nitrogen leaching due to farming activity is 5.56 kg N ha–1. In the paper, there are presented nitrogen leaching mitigation measures, which are most reasonable for southern Lithuania. The most effective measures are the ones that could be applied on a bigger part of the watershed, e. g., balanced fertilisation would reduce nitrogen load by 7.95%, reduced soil tillage by 16.6%. The total effectiveness of all the discussed measures for the entire watershed is 36.4%. |
