The total use of plant protection products (PPPs) in Slovenia has decreased by nearly two-thirds over the past 30 years — from 2,031 tons in 1992 to 733 tons in 2024. Because of the large share of permanent crops, PPP use per hectare in Slovenia remains relatively high, but comparable to other EU countries with a similar production structure. Over the last decade, Slovenia has significantly reduced the intensity of PPP use on utilised arable land and permanent crops: from an average of 6.57 kg/ha in 2000–2010 to only 3.63 kg/ha in 2024.

The response of agricultural holdings to the agricultural policy and favourable market opportunities, which support the spreading of organic farming has been growing every year. The area intended for organic farming has increased in the period 1999–2023 from 2,400 ha to 54,602 ha, or from 0.5% to 11.4% of the total utilised agricultural area. The structure of agricultural land with organic farming is strongly dominated by grassland (78% in 2023), which shows that livestock farms more frequently convert to organic farming.

In the period 1992–2024 the consumption of mineral fertilizers in Slovenia was reduced by 41%. In the same period the consumption of plant nutrients (N, P₂O₅, K₂O) per hectare of utilized agricultural area also reduced by 45%. The average consumption per hectare of utilized agricultural area was 61 kg N, 25 kg P₂O₅ and 30 kg K₂O. In the period 2014–2023 the average consumption of nitrogen in Slovenia was lower (58 kg N/ha) than in EU member states (60 kg N/ha).

In 2023, drinking water monitoring was carried out in supply zones (water supply systems) that supply 50 or more persons (92.3% of the population). Large, medium and some of small supply zones that supply more than 500 (87.7%) inhabitants, generally have adequate drinking water quality. The smallest supply zones that supply 50-500 inhabitants are the least regulated, in comparison to larger due to the fecal contamination, as some with karst water resources.

Slovenia reported one to two waterborne outbreaks per year during 2014–2024, except in 2015, 2017–2020 and 2023-2024, when no outbreaks were reported. Last outbreak was reported in 2022 in the Savinja region, caused by the norovirus genotype GII.6. During 2014–2024 between 3 and 405 cases were reported. Confirmed causative agents were Cryptosporidium parvum, Escherichia coli, rotavirus, norovirus, Bacillus cereus, Campylobacter jejuni, Salmonella Typhimurium and Francisella tularensis.
