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.

(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), (3) and (4) amounts to not less than 1 % by weight, it must be declared

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

The fertilisers may not contain Thomas slag, aluminium calcium phosphate, calcined phosphates, partially solubilised phosphate or rock phosphates

If the water-soluble P2O5 is less than 2 % only solubility 2 shall be declared

If the water-soluble P2O5 is at least 2 %, solubility 3 will be declared and the water-soluble P2O5 content must be stated
