Fertilizers. Determination of the complexed micro-nutrient content and of the complexed fraction of micro-nutrients Ingestion-build-223009 Manufacturers of circuit control devices1 Scope This European Standard specifies a general method 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 after subtraction of the chelated micro nutrients content, but it does not identify the individual complexing agents. This procedure concerns EC fertilizers which contain complexed micro nutrients
