BS EN 16962 is a standard that covers technical specifications for extraction of water soluble micro-nutrients and removal of organic compounds in fertilizers that enables the determination of boron and molybdenum that enhance the nutritional value, water solubility and stable performance in fertilizers.
BS EN 16962 specifies a method for the extraction of water soluble forms of boron, cobalt, copper, iron, manganese, molybdenum, and zinc from mineral fertilizers containing one or more micro-nutrients and the procedure for removal of organic compounds from the water extracts.
BS EN 16962 on the extraction of water soluble micro-nutrients and removal of organic compounds in fertilizers applies to:
The water extraction method is dependent on temperature and extraction time, on the ratio of water/sample and intensity of the extraction. It is applied only in some cases to determine boron and molybdenum by spectrophotometric methods, determination of boron by acidimetric titration and gravimetric determination of molybdenum. The removal of organic matter is achieved by boiling after adding hydrogen peroxide.
BS EN 16962 provides you guidance on principle, sampling, reagents, apparatus, procedure, precision, and test report enabling you to extract water soluble micronutrients from fertilizers.
BS EN 16962 provides you guidance on the sample preparation of test solutions, including two test solutions; these methods are based on the level of micro-nutrient content in the test solutions.
The precision of the method in BS EN 16962 is based on inter-laboratory tests based on measurement methods in EN 16965 and EN 16963 that ensure the accuracy and validity of the method.
Guidance in BS EN 16962 enables you to extract water soluble micro-nutrients in fertilizers and remove organic compounds that can be further analysed that enhance the stability and water solubility in fertilizers.
