BS EN 16198 is a standard that serves technical specifications for determining magnesium in fertilizers by complexometry, enabling the prevention of magnesium deficiency in plants.
BS EN 16198 specifies a method for the determination of magnesium in fertilizer extracts by complexometry.
BS EN 16198 method is applicable to the following EC fertilizer extracts for which the determination of total magnesium and/or water-soluble magnesium is provided for according to the Regulation (EC) No 2003/2003, Annex I [3]:
BS EN 16198 on determining magnesium in fertilizers by complexometry applies to:
The primary core of the chlorophyll molecule in plant tissue is magnesium. As a result, if Mg is low, the lack of chlorophyll causes plant growth to be poor and stunted. Magnesium also aids in the activation of enzyme systems. Chlorophyll can't process the solar energy for photosynthesis if it doesn't have enough magnesium.
BS EN 16198 provides users guidance on a method for the determination of magnesium in fertilizers by complexometry. BS EN 16198 also provides users with a step-by-step procedure for the method, enabling users to do the method correctly.
BS EN 16198 provides users guidance on principle, sampling, reagents, apparatus, preparation of the extraction solution, procedure, calculation, expression of results, precision and test report, enabling the accurate detection of magnesium in fertilizers.
With obedience and compliance to BS EN 16198, users can develop and assess fertilizers to determine magnesium in fertilizers, ensuring plant growth for improved crop yields.
BS EN 16198:2012 supersedes DD CEN/TS 16198:2011, which is now withdrawn.
