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

EU. EC Fertiliser Type List: Annex I A - E.1, E.2.4 & G, Annex II, Regulation 2003/2003/EC, as amended by Regulation (EU) 2021/862, 31 May 2021

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. Regulation 2003/2003/EC has been repealed with effect from 16 July 2022 by Regulation 2019/1009/EU.

(1) Water-soluble P2O5 (2) P2O5 soluble in neutral ammonium citrate (3) P2O5 soluble in neutral ammonium citrate and in water

Other data
Total nitrogen

If any of the forms of nitrogen (2) to (4) amounts to at least 1 % by weight, it must be declared

One of the forms of nitrogen (5) to (7) (as appropriate)

Nitrogen form (7) must be declared in the form of nitrogen (8) and (9)

An NP fertiliser free of Thomas slag, calcined phosphate, aluminium-calcium phosphate, partially solubilised rock phosphate and rock phosphate must be declared in accordance with solubilities (1), (2) or (3): - when the water-soluble P2O5 does not amount to 2 %, solubility (2) only shall be declared, - when the water-soluble P2O5 is at least 2 %, solubility (3) shall be declared, and the water-soluble P2O5 content must be indicated [solubility (1)]. The P2O5 content soluble in mineral acids only must not exceed 2 %. The test sample for determining solubilities (2) and (3) shall be 1 g
