Chemical Stability of the Fertilizer Chelates Fe-EDDHA and Fe …
The most commonly used chelating agent is EDTA (ethylenediaminetetraacetic acid or its salt). ... The amount of chelated iron in Fe-EDDHSA and its solubility make it possible to use it at a dose of 1.4–1.7 lower than that of Fe-EDDHA, showing similar effectiveness and stabilizing microelement at pH 4–9 [16,17,18,19].
