In the period 1992–2021 nitrogen surplus in Slovenian agriculture decreased. Trend analysis for this period shows that gross nitrogen surplus decreased on average by 1.5 kg N/ha per year or by 54%, and the net surplus by 1.5 kg N/ha per year or by 87%. The lower surplus was mainly due to a 50% increase in nitrogen removal by crops and a 4% decrease in nitrogen input per hectare of utilized agricultural area. A lower excess of nitrogen indicates better nitrogen management in agriculture and consequently a reduction in emissions of nitrogen compounds into the environment.


In Slovenia, alluvial aquifers present 60 % of the drinking water sources, and karst-fractured aquifers present 40 %. Due to populated areas and intensive agricultural production, alluvial aquifers are exposed to greater risks of pollution with nitrates.


In High Nature Value areas, agriculture can ensure a suitable level of biodiversity by means of appropriate technological solutions. Extensive management methods facilitate conservation of the diversity of species and habitats, thus helping preserve unique landscapes with rich cultural and natural heritage. According to the estimates made in Slovenia on the basis of the CORINE data on land use and data on agricultural land use, between 60% and 80% of all utilised agricultural areas in Slovenia are located in High Nature Value farmland areas.
