No. EN 13535:2001 EPage 2 EN 13535:2001 BSI 07-2001 Foreword This European Standard has been prepared by Technical Committee CEN /TC 260, Fertilizers and liming materials, the Secretariat of which is held by DIN. This European Standard shall be given the status of a national standar
14、d, either by publication of an identical text or by endorsement, at the latest by September 2001, and conflicting national standards shall be withdrawn at the latest by September 2001. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries
15、are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.Page 3 EN 13535:2001 BSI 07-2001 Introduction The classifi
16、cation 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 de
17、termine 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 leav
18、es 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
19、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 t
20、ext 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 appl
21、ies (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 fe
22、rtilizers 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 cyanami
23、de, urea and its condensation and association products and bone superphosphate may, by convention, be classed as inorganic fertilizers.Page 4 EN 13535:2001 BSI 07-2001 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 whi
24、ch 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 d
25、o 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 fertil
26、izers 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 cont
27、ents 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.
28、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 dec
29、larable 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 whic
30、h 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 an
31、d 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
32、“amendement minral basique” is now preferred to “amendement calcique et/ou magnsien (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 co
33、ntaining 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.Page 5 EN 13535:2001 BSI 07-2001 4.1.2.2.2 Ca, Mg oxides and hydroxides: Inorganic liming materials containing one or both of the elements calci

NOTE This catego
40、ry 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,
41、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 d
42、eclarable 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 1 The ter
45、m “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.
46、 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 materia
47、ls in which fertilizer has been incorporated can equally be classified as organic soil improvers containing fertilizer.Page 7 EN 13535:2001 BSI 07-2001BS EN 13535:2001 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is the independent national body responsible for prep
