The consumption of mineral fertilisers in Slovenia was reduced by 30,6 % in the period 1992-2010. The consumption of nutrients (N, P2O5, K2O) per hectare of utilised agricultural area was also reduced from 135 kg/ha to 103 kg/ha, or by 23.6%. In the period 1992-2010 we used 63 kg N, 30 kg P2O5, and 37 kg K2O in average per hectare of utilised agricultural area.

- balanced consumption of mineral fertilisers, gradual increase of the scope of ecological production, and prevention of pressure on soil both from the point and the non-point sources,
- fertilise plants in a way to make the best use of nutrients without being wasted into the groundwater and the atmosphere
- reduce and prevent further pollution of waters with nitrates from the agricultural production.
