ISO 22145 establishes an overview of the relevant methods for the determination of calcium and magnesium as defined in ISO 8157.
ISO 22145 is applicable to any mineral soil amendment, neutral, basic, or acid containing calcium and/or magnesium.
ISO 22145 on Calcium and magnesium in fertilizers and soil conditioners is useful for:
The determination of calcium and magnesium content of mineral soil amendments, and especially total content, is part of the assessment of their properties through their chemical characteristics.
In order to improve efficiency, ISO 22145 provides a list of existing and relevant methods published all over the world. As most of these methods claim total content, no significant differences are expected between existing methods, provided calibration, sample preparation, dilution, and measurement procedures are operated as described. Total extraction is supposed to be the strongest method and to give the highest result.
Enhance the quality of Fertilizers and soil conditioners with ISO 22145 that gives you an overview of the relevant methods for the determination of calcium and magnesium.
