Subject of the standard: | This document specifies the method for the determination of free, chelated or complexed micronutrients and chelating and/or complexing agents present in compound inorganic micronutrient fertilizers. This method applies to compound inorganic micronutrient fertilizers when micronutrients are chelated and/or complexed. The method is based on the determination of the following specific parameters : - the water-soluble micronutrient concentration; - the fraction of chelated micronutrients in relation; - identification of chelating agents EDTA, DTPA, HEEDTA, IDHA, [S,S]–EDDS, [o,o] EDDHA, [o,o] EDDHMA, [o,p] EDDHA, HBED and EDDHSA; - the fraction of complexed micronutrients; - identification of complexing agents (lignosulfonates, heptagluconic acid (HGA)). |
