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.
