Excessive input of nitrogen and phosphorus into water systems causes eutrophication. Efforts to reduce nitrogen and phosphorus losses from agriculture in the Baltic Sea region are crucial. The aim of the study is to assess the impact of nitrogen application rates in the form of mineral fertilizer on concentrations of Ntot, NO3-N, Ptot, and PO4-P (mg L-1) in runoff at the level of experimental fields. This study analyzed data from October 2014 to April 2022 collected from the Mellupite monitoring station, where exp...
