EU. Fertiliser List: Annex I A-E.1, E.2.4 & G, Annex II

EU Regulation 2003/2003 consolidates all the European Union rules that apply to fertilisers, and ensures that the technical requirements outlined in the regulation are implemented uniformly. The regulation only applies to mineral fertilisers consisting of one or more plant nutrients. Annex I lists fertiliser types according to their specific characteristics, while Annex II provides a list of associated tolerances.

Water-soluble K2O

Other data
Total nitrogen

If any of the forms of nitrogen (2), (3) and (4) amounts to not less than 1 % by weight, it must be declared

Nitrogen from urea formaldehyde

If the biuret content is less than 0,2 %, the words 'low in biuret' may be added

Water-soluble potassium oxide

The words 'low in chloride' may be used only where the Cl content does not exceed 2 %

The chloride content may be declared
