Introduction

The classification scheme includes an explanation of the meaning of each heading and clearly assigns each fertilizer or liming material to an appropriate group whilst recognizing that a few fertilizers or liming materials may be classified differently in some countries

The limits for nutrient contents which determine each class can be subject to national legislation

Owing to historical and legislative differences between countries, this European Standard uses, in the descriptions, terms only and not chemical symbols to denote nutrients This avoids ambiguity between the elemental or oxide forms and leaves each country free to declare nutrient contents according to national requirements

The descriptions given in clause 4 are not definitions but are given to explain the definitions to be found in

EN 12944 These descriptions may not necessarily correspond with those used in national legislation

1 Scope

This European Standard establishes a classification scheme for fertilizers and liming materials

2 Normative references

This European Standard incorporates by dated or undated reference, provisions from other publications These normative references are cited at the appropriate places in the text and the publications are listed hereafter For dated references, subsequent amendments to or revisions of any of these publications apply

to this European Standard only when incorporated in it by amendment or revision For undated references the latest edition of the publication referred to applies (including amendments)

EN 12944 (all parts), Fertilizers and liming materials — Vocabulary.

3 Terms and definitions

For the purposes of this European Standard, the terms and definitions given in EN 12944 apply

4 Classification

NOTE The classification scheme is shown in Figure 1

4.1 Inorganic fertilizers and liming materials

4.1.1 Inorganic fertilizers: Fertilizers added to the soil especially for the nutrition of plants and in which

the declared nutrients are in the form of inorganic salts obtained by extraction and/or by physical and/or chemical industrial processes

NOTE Calcium cyanamide, urea and its condensation and association products and bone superphosphate may,

by convention, be classed as inorganic fertilizers

4.1.1.1 N, P, K fertilizers

4.1.1.1.1 Straight N, P, K fertilizers

4.1.1.1.1.1 Straight nitrogenous fertilizers (N): Fertilizers which have a declarable nitrogen content and

which may contain other elements, but which do not have declarable phosphorus and/or potassium contents

4.1.1.1.1.2 Straight phosphatic fertilizers (P): Fertilizers which have a declarable phosphorus content

and which may contain other elements, but which do not have declarable nitrogen and/or potassium contents

4.1.1.1.1.3 Straight potassic fertilizers (K): Fertilizers which have a declarable potassium content and

which may contain other elements, but which do not have declarable nitrogen and/or phosphorus contents

4.1.1.1.2 Compound N, P, K fertilizers

4.1.1.1.2.1 NP compound fertilizers: Fertilizers which have declarable nitrogen and phosphorus contents

and which may contain other elements, but which do not have a declarable potassium content

4.1.1.1.2.2 NK compound fertilizers: Fertilizers which have declarable nitrogen and potassium contents

and which may contain other elements, but which do not have a declarable phosphorus content

4.1.1.1.2.3 PK compound fertilizers: Fertilizers which have declarable phosphorus and potassium

contents and which may contain other elements, but which do not have a declarable nitrogen content

4.1.1.1.2.4 NPK compound fertilizers: Fertilizers which have declarable nitrogen, phosphorus and

potassium contents and which may contain other elements

4.1.1.2 Ca, Mg, Na, S fertilizers: Fertilizers which contain one or more of the elements calcium,

magnesium, sodium and sulfur and which do not have declarable nitrogen, phosphorus or potassium contents and are, therefore, not classified as straight or compound N, P, K fertilizers

NOTE These products differ from Ca, Mg liming materials in that their principal function is the nutrition of plants

4.1.1.3 Micro-nutrient fertilizers: Fertilizers which have declarable contents of one or more

micro-nutrients, but which do not have declarable nitrogen, phosphorus, potassium, calcium, magnesium or sodium contents

4.1.2 Inorganic liming materials

4.1.2.1 General description

Inorganic soil improvers containing one or both of the elements calcium and magnesium, generally in the form of the oxide, hydroxide, carbonate or silicate, intended principally to maintain or raise the pH of the soil

or water

NOTE 1 They do not have declarable nitrogen, phosphorus or potassium contents

NOTE 2 With respect to liming materials, in France, the expression “amendement minéral basique” is now preferred to “amendement calcique et/ou magnésien (liming product)” in the meaning of a product having an effect on the pH of the soil

4.1.2.2 Liming materials of natural origin

4.1.2.2.1 Ca, Mg carbonates (limestone, dolomite, chalk): Inorganic liming materials containing one or

both of the elements calcium and magnesium, in the form of carbonate, intended principally to maintain or raise the pH of the soil or water

4.1.2.3.1 Industrial products containing Ca, Mg carbonates, oxides and hydroxides: Inorganic liming

materials containing one or both of the elements calcium and magnesium, generally in the form of oxides, hydroxides or carbonates, obtained as products from industrial processes, intended principally to maintain or raise the pH of the soil or water

4.1.2.3.2 Industrial products containing Ca, Mg silicates: Inorganic liming materials containing one or

both of the elements calcium and magnesium, generally in the form of silicates, obtained as products from industrial processes such as blast furnaces and converters, intended principally to maintain or raise the pH

of the soil or water

4.1.2.3.3 Other inorganic liming materials: Inorganic compounds with liming properties such as ashes

and soda, or mixtures of products classified under 4.1.2.2.1, 4.1.2.2.2, 4.1.2.3.1 and 4.1.2.3.2, intended principally to maintain or raise the pH of the soil or water

4.2 Organic fertilizers

4.2.1 General description

Carbonaceous materials added to the soil specifically for the nutrition of plants, and having a declarable content of nitrogen and/or phosphorus and/or potassium of vegetable and/or animal origin

4.2.2 Organic nitrogenous fertilizers: Materials of vegetable and/or animal origin in which the

declarable nitrogen content is organically combined with carbon and which may contain other elements, but which do not have declarable phosphorus or potassium contents

4.2.3 Synthetic organic nitrogenous fertilizers: Nitrogenous fertilizers in which the nitrogen is

combined with carbon by industrial organic synthesis

NOTE This category only exists in those countries in which urea condensates are not classified as inorganic fertilizers

4.2.4 NP organic fertilizers: Organic fertilizers which have, in addition to nitrogen, a declarable content

of phosphorus of vegetable and/or animal origin, and which may contain other elements, but which do not have a declarable potassium content

NOTE 1 In some countries, bone meals are classified as semi-organic fertilizers

NOTE 2 Synthetic NP organic fertilizers may be produced in some countries

4.2.5 NK organic fertilizers: Organic fertilizers which have, in addition to nitrogen, a declarable content

of potassium of vegetable and/or animal origin, and which may contain other elements, but which do not have a declarable phosphorus content

NOTE Synthetic NK organic fertilizers may be produced in some countries

4.2.6 NPK organic fertilizers: Organic fertilizers which have, in addition to nitrogen, declarable contents

of phosphorus and potassium of vegetable and/or animal origin, and which may contain other elements

4.2.7 NP, NK, NPK fertilizers containing synthetic organic nitrogen: NP, NK or NPK compound

fertilizers containing declarable amounts of synthetic organic nitrogen

4.3 Fertilizers of mixed origin

4.3.1 Organo-mineral fertilizers: Products in which the declarable nutrients are of both organic and

inorganic origin, obtained by mixing and/or chemical combination of organic fertilizers and inorganic fertilizers

NOTE 1 The term “semi-organic fertilizer” is used in some countries for these products

NOTE 2 In some countries in which urea condensates are not classified as inorganic fertilizers, the term

“organo-mineral fertilizer” is reserved for those products which contain nitrogen of vegetable and/or animal origin only

4.3.2 Organic-based fertilizers: Products in which the declarable nutrients are of inorganic origin but

which are mixed with organic materials such as peat or lignite

NOTE 1 In some countries, peat-based products are classified as semi-organic fertilizers

NOTE 2 In some countries, organic materials in which fertilizer has been incorporated can equally be classified as organic soil improvers containing fertilizer
