This article deals with the impact of diffuse and point sources of nitrogen and phosphorus pollution on the environment in Goričko Nature Park. The park was divided into three parts: the Ledava, Big Krka (Velika Krka), and Kobilje Creek (Kobiljski potok) basins, which were then compared. The surface waters were monitored and their chemical composition was examined. All three areas are characterized by elevated levels of nitrogen and phosphorus compounds in the water. Nitrogen and phosphorus pollution results from unregulated manure pits on livestock farms, unregulated sewage systems, and runoff of nitrogen and phosphorus compounds from farmland.
