Impact of different proportion of agricultural land in river catchments on nitrogen surface streams pollution

Year, pages: 2020, 56 - 64

Water quality is threatened particularly in regions where the agricultural landscape is prevailing. This study presents results of the comparison of yearly total nitrogen emissions and contribution of different emission pathways on this emissions into surface streams for three river catchments in Slovakia territory with the contrasting proportion of agricultural land to the total area of the river catchment. For nitrogen yearly emissions and pathways detection, the numerical model MONERIS has been used. Results indicate that in river catchments with a higher proportion of agricultural land higher contribution of nitrogen emission carried out mainly via groundwater (especially in lowland), but also via agricultural erosion and drainage system.
