Data are published in order to present the annual consumption of main plant nutrients, i.e. active substances derived from mineral fertilisers, at the level of the Republic of Croatia.

The published data show the total quantity of active substances used in the utilised agricultural area. Active substances include nitrogen (N) and phosphorus (P).
