Fertilisers Regulation, Annex I, A - E.1, E2.4 and G, Annex II

This list contains Annex I fertiliser types according to their specific characteristics, and Annex II associated tolerances. Regulation 2003/2003/EC consolidates all European Union rules that apply to fertilisers, and ensures that the technical requirements it outlines are implemented uniformly. The Regulation only applies to mineral fertilisers consisting of one or more plant nutrients.
