Scope

This document specifies a method (Method A) for the determination of the micronutrients complexed by complexing agents in fertilizers. The method allows the determination of the total concentration of each complexed micronutrient in complexes, but it does not identify the individual complexing agents. This standard also includes two complementary methods (Method B and C) that allow to identify
ignosulfonates as complexing agent.
