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.

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).

The phosphorus (P) budget in agriculture decreased by 109 % in the period 1992–2024. The decline is the result of a decreased P intake with mineral and livestock fertilizers, as well as the consequence of increased P uptake by agricultural crops. The period up to 2003 was characterized by a surplus of 11 to 16 kg per hectare. Thereafter, the surpluses decreased and reached an average value of +0.4 kg P per hectare in the last five-year period. A realistic comparison of the surplus with other EU Member States is not possible.

Trends in annual precipitation are not as obvious as temperature trends. Changes between years and differences between regions are significant. According to climate change projections, annual precipitation will increase slightly while changes in seasonal precipitation will be more noticeable. Summer conditions are the most worrying, because less precipitation and higher temperature might result in higher frequency of droughts. In winter, more precipitation may lead to an increase in flooding events.

Comparison of periods 1961–1990 and 1991–2020 on the chosen representative stations around Slovenia shows decrease of heating degree days by around 10 % and multiple increase of cooling degree days. With projected continuous temperature raise until the end of 21st century, those trends are expected to continue. Thus, in Slovenia, energy demand for cooling will increase in the warmer period of the year, while the energy demand for heating will decrease in colder period of the year. Same trend is projected for Europe in general.
