BS EN 13651 is a standard that serves technical specifications for the extraction of calcium chloride in soil improvers and growing media, enabling the identification and detection of nutrients in soil improvers and growing media.
BS EN 13651 specifies an extraction method for the routine determination of calcium chloride/DTPA (CAT-method) extractable nutrients and elements in soil improvers or growing media.
Note: BS EN 13651 is not applicable to liming materials and preformed materials such as mineral wool slabs and foam slabs.
BS EN 13651 on the extraction of calcium chloride in soil improvers and growing media applies to:
Soil improvers are substrates that help to improve the structure and fertility of the soil. Soil improvers are mixed into the top layer of the garden, in the root zone of the plants. Growing media are mixes of components that give plants water, air, nutrients, and support.
BS EN 13651 provides users guidance on the CAT method for the determination of calcium chloride and other nutrients and elements in soil improvers and growing media. BS EN 13651 also provides users with a step-by-step procedure for the method, enabling users to do the method correctly.
BS EN 13651 provides users guidance on principle, reagents, apparatus, test sample, procedure, determination of extracted nutrients and elements, expression of results, precision, and test report, enabling routine analysis for ensuring the consistency and quality of soil improvers and growing media.
BS EN 13651 provides users information in a tabular form for soluble elements in composted bark, bio waste, clay peat, coarse peat, composted sludge, and more for further analysis and determination of elements such as ammonium ion, nitrate-nitrogen, phosphorus, potassium, and more.
With obedience and compliance to BS EN 13651, users can assess soil improvers and growing media, to ensure the quality, effectiveness and potency in agricultural applications.
