This document is applicable to liming materials, which contain oxides, hydroxides, carbonates or silicates of the nutrients calcium (Ca) or magnesium (Mg) and the function of which is to correct soil acidity.
This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants and where the following category liming materials is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If liming materials is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.
In case of chromium VI determination, in a fertilizing product blend containing organic matter, the European Standard for liming materials and inorganic fertilizers is not applicable.
This document specifies references to the methods for the determination of the following physical and chemical properties and specific contaminants in liming materials:
— determination of the cadmium content;
— determination of the chromium VI content;
— determination of the mercury content;
— determination of the nickel content;
— determination of the lead content;
— determination of the arsenic content;
— determination of the total chromium content;
— determination of neutralizing value;
— determination of the reactivity;
— determination of the grain size/granulometry;
— determination of the total CaO content;
— determination of the total MgO content;
— determination of the dry matter content;
— determination of the copper and zinc content;
— determination of the phosphonates content.
— determination of the chloride content;
— determination of quantity (indicated by mass or volume).
