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.

Annex Section
A Inorganic straight primary nutrient fertilisers
Minimum content of nutrients (percentage by weight). Data on the expression of nutrients. Other requirements Other Requirements
Nitric nitrogen and ammoniacal nitrogen, each of these two forms of nitrogen accounting for about half the nitrogen present. See Annexes and III.2 of this regulation, if required
N Minimum content
20 % by weight
N Expressed as
As ammoniacal and nitric nitrogen
Nutrient declaration
Total nitrogen

Nitric nitrogen

Ammoniacal nitrogen

Other data
The designation 'calcium ammonium nitrate' is exclusively reserved for a fertiliser containing only calcium carbonate (for instance limestone) and/or magnesium carbonate and calcium carbonate (for instance dolomite) in addition to ammonium nitrate

The minimum content of these carbonates must be 20 % and their purity level at least 90 %

A.1 Nitrogenous fertilisers
0.8 (if up to and including 32% of primary nutrient) or 0.6 (if more than 32%)
Production and Ingredients
Chemically obtained product containing ammonium nitrate as its essential ingredient, which may contain fillers such as ground limestone, calcium sulphate, ground dolomite, magnesium sulphate, kieserite
Type designation
Ammonium nitrate or calcium ammonium nitrate
