In the period 1992–2022 the consumption of mineral fertilizers in Slovenia was reduced by 38%. In the same period the consumption of plant nutrients (N, P2O5, K2O) per hectare of utilized agricultural area also reduced by 30%. The average consumption per hectare of utilized agricultural area was 61 kg N, 25 kg P2O5 and 31 kg K2O. In the period 2012–2019 the average consumption of nitrogen in Slovenia was lower (57 kg N/ha) than in EU member states (63 kg N/ha). In the same period the consumption of phosphorus (19 kg P2O5/ha) was higher than in EU member states (16 kg P2O5/ha).


The indicator represents the consumption of mineral fertilizers in Slovenia in the period 1992–2022. Their total consumption and consumption of the main plant nutrients (nitrogen, phosphorus, potassium) are presented. The consumption of plant nutrients per hectare of utilized agricultural area is calculated and a comparison of nitrogen and phosphorus consumption with the countries of the European Union in the period of 2012–2019 is given.

Mineral fertilizers are substances, regardless of their physical state, which contain plant nutrients and are added to the soil or plants to improve growth, increase yields, improve crop quality or soil fertility and are obtained in an industrial process (Mineral Fertilizers Act, Ur. l. RS, 29/06).

Goals

  • Balanced consumption of mineral fertilizers, gradual increase in the volume of organic production and prevention of soil pollution from point and diffuse sources.
  • Fertilize the plants in such a way that they can make the most of the nutrients and that they are not lost to groundwater and to the atmosphere.
  • Reduce and prevent further pollution of waters with nitrates from agricultural production.

 


In the period 1992–2022 the consumption of mineral fertilizers in Slovenia reduced by 38%. In that period the consumption of mineral fertilizers per hectare of utilized agricultural area also reduced by 3.6 kg/year or by 30%. The average nutrient consumption was 117 kg/ha (61 kg N/ha, 25 kg P2O5/ha and 31 kg K2O/ha). In that period the consumption of N per ha reduced by 16%, P2O5 by 62% and K2O by 65%. Among plant nutrients, N (53%) predominates in the composition of mineral fertilizers, followed by K2O (26%) and P2O5 (21%). This fact confirms that mineral fertilizers in Slovenia are mainly used for top-dressing with nitrogen (use of nitrogen fertilizers), and fertilization with phosphorus and potassium is combined with the use of livestock fertilizers in pre-sowing tillage.

The reduction in the consumption of mineral fertilizers can be attributed to the requirements of the Nitrates Directive and the principles of good agricultural practice in fertilization, to which agricultural holdings have been committed in recent years, especially after 2004, when Slovenia joined the EU. Both documents pay more attention to the use of livestock manure and the consideration of plant nutrients in livestock manure when planning fertilization with mineral fertilizers. As agricultural holdings must have fertilization plans in place, in which the plant nutrients used from livestock manure are also evaluated, the consumption of mineral fertilizers is reduced accordingly.

The consumption of nitrogen in Slovenia was in the period 2012–2019 lower (57 kg N/ha) than in the EU Member States (63 kg N/ha). The highest consumption of nitrogen was in Netherlands (121 kg N/ha), Belgium (113 kg N/ha) and Czechia (103 kg N/ha), and the lowest in Romania (27 kg N/ha) and Portugal (30 kg N/ha).

The consumption of phosphorus in Slovenia was in the period 2012–2019 higher (19 kg P2O5/ha) than in the EU Member States (16 kg P2O5/ha). The highest phosphorus consumption was in Cyprus (41 kg P2O5/ha) and Poland (24 kg P2O5/ha) and the lowest in Netherlands (6 kg P2O5/ha).
