BS EN 16965 is a standard that serves technical specifications for the determination of cobalt, copper, iron, manganese and zinc in fertilizers that promote essential plant processes and growth that increase crop yield.
BS EN 16965 specifies a method for the determination of cobalt, copper, iron, manganese and zinc in fertilizer extracts using flame atomic absorption spectrometry (FAAS).
BS EN 16965 method is applicable to water and aqua regia fertilizer extracts obtained according to EN 16962 and EN 16964.
Note: In most cases, the presence of small quantities of organic matter will not affect determinations by FAAS and it is not necessary to apply organic matter removal.
BS EN 16965 on the determination of cobalt, copper, iron, manganese and zinc in fertilizers applies to:
Boron, cobalt, copper, iron, manganese, molybdenum and zinc are micronutrients in fertilizers. Micronutrients facilitate vital plant processes and growth, translating into nutrient-rich food for animals and humans. Determination of micronutrients enables the classification of the quality and nutritional value of fertilizers.
BS EN 16965 provides you guidance on the flame atomic absorption spectrometry (FAAS) method for determining micronutrients in fertilizers. BS EN 16965 also provides you with a step-by-step procedure for the method that ensures you do the method correctly.
BS EN 16965 also provides guidance on minimizing the effect of interferences for the method through matrix matching which enables you to get accurate results.
Guidance in BS EN 16965 enables you to determine the content of boron, cobalt, copper, iron, manganese, molybdenum and zinc in mineral fertilizers ensuring the quality and nutritional value of fertilizers.
