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

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.
