This standard defines a method for the treatment with a cation exchange resin for the determination of the chelated
micro-nutrient content and the chelated fraction of the micro-nutrients (trace elements) cobalt, copper, iron,
manganese, and zinc in fertilizers.
This method applies to fertilizers containing one or more of the micro-nutrients cobalt, copper, iron, manganese,
and zinc, chelated by one or more chelating agents of the group of the polyamino polycarboxylic acids, previously
determined according to EN 13368-1 and EN 13368-2, either alone or in combination with primary (N, P, K) and/or
secondary (S, Na, Ca, Mg) nutrients.
The limit of determination of the chelated micro-nutrient content varies between 0,005 % in simple matrices with
high amounts of chelated micro-nutrients, and 0,5 % in more complex cases (see 7.2).
