39、or determining the neutralizing value (NV) (see EN 12945) and the reactivity (see EN 13971 and EN 16357) of liming materials are not always appropriate indicators for any material claimed to have a liming effect in the soil, particularly materials with a high organic matter content. The biological m
40、ineralization of organic matter contained in some products can, in the field, have an effect on pH, which cannot be quantified by the chemical methods. The two methods described in this document overcome these problems. Both methods characterize products through their effect on the pH of a soil unde
41、r controlled, standard conditions, and establish the efficiency of products when applied to a standard soil. Method A specifies a reference soil with tight characteristics with respect to pH range before incubation, cation exchange capacity (CEC), mass fraction of organic carbon, and mass fraction o
42、f particles finer than 0,002 mm (clay). Method B can apply the same reference soil as Method A, but also allows alternative standard soils with a wider content of particles finer than 0,002 mm (clay), and a wider range of mass fraction of organic matter. Clay and organic matter are the decisive reac
43、tants to a liming material However, attention is drawn to the limitations of these methods. They are laboratory methods carried out under controlled conditions and care should be taken when applying the results to field conditions. The quality of incorporation of the liming material into the soil an
44、d the eventual need to break down the product agglomerates, together with the soil and climate conditions, can affect the results. Nevertheless, these methods allow a comparison of the potential neutralizing effect of liming products under optimum and reproducible conditions. BS EN 14984:2016g8g17g3

Method A measures the chan
46、ges to the soil pH resulting from the addition of any material claimed to have a liming effect on a standard soil, measured over a period of one month. Method B assesses the efficiency of any material claimed to have a liming effect, using a range of defined soils and measured over a period of up to
47、 2,5 years. The methods are not applicable to mineral products coarser than 6,3 mm for method A or 20 mm for method B, determined according to EN 12948. NOTE These methods allow comparison of products under controlled climatic conditions but do not replace field experiments. 2 Normative references T
