In the period 1992–2023 nitrogen surplus in Slovenian agriculture decreased. Trend analysis for this period shows that gross nitrogen surplus decreased on average by 1.4 kg N/ha per year or by 54%, and the net surplus by 1.2 kg N/ha per year or by 85%. The lower surplus was mainly due to a 43% increase in nitrogen removal by crops and a 6% 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.
