BS EN 14069:2017EN 14069:2017 (E) 4 Introduction Throughout the member countries of CEN, regular liming to regulate the soil pH level and to neutralize the effect of soil acidification is a well-establish
25、ed and essential agricultural operation on all soils in humid climates and under all systems of agricultural cultivation. Liming improves soil fertility and supplies essential plant nutrients. Liming materials are also used in forest liming, lake liming and the liming of water catchment areas. A wid
26、e range of natural geological deposits of liming materials is found in all member countries of CEN. Some industrial processes produce materials acceptable as liming products. This very wide range of material differs substantially in both chemical and physical properties. The use of these various mat
27、erials will vary according to the type of material. Still, this standard specifies the main properties of the liming materials used in Europe. However, for the purpose of comparison of these products, it is necessary to describe and specify the minimum requirements of a liming material. In the frame
28、 of the 1st revision of this European Standard the minimum requirements laid down in Regulation (EC) No 463/2013 2 amending Regulation (EC) No 2003/2003 1 concerning liming materials have been taken into account. Liming materials in Europe show a large diversity due to factors as climate and type of
29、 crops, production, transport, storing and spreading of lime adapted to regional conditions. Standard quality covers these varying liming materials, whilst Fine quality credits rapidly dissolving materials needed for certain specialized agricultural productions or to allow the dissolution of the lim
30、ing material in some soil types having a higher pH value in a rapid and controlled way. BS EN 14069:2017EN 14069:2017 (E) 5 1 Scope This European Standard describes and specifies the requirements of products of natural origin and products from industrial processes of basic and fine quality to be use
31、d as liming materials in agriculture for raising the pH of soil (and water). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

38、the terms and definitions given in EN 12944-1 and EN 12944-3 apply. 4 Denominations and specifications for liming materials The denominations (type designations), specifications and elements to be declared are specified in Table 1 to Table 6 as follows: Table 1: Natural limes Table 2: Oxide and hydr
39、oxide limes of natural origin Table 3: Limes from industrial processes Table 4: Silicate limes Table 5: Mixed limes Table 6: Mixtures of liming materials with other EC fertilizer types Granulated liming materials which are produced by aggregating smaller primary particles shall break down when stirr
40、ed in water into particles with fineness distributions as specified in the type descriptions, and as measured using the method specified in EN 15704. All the properties mentioned in the Table 1 to Table 6 refer to the product as supplied unless otherwise specified. All the neutralizing requirements
41、are expressed as CaO-equivalent and as HO-equivalent in brackets. For mixed limes other than specified in Table 5, users of these products shall check the compliance of these products with the national regulations for agricultural liming materials. For products obtained by mixing, the type designati
