METHOD OF PRODUCING COMPLEX CHELATED MICROFERTILIZERS Russian patent published in 2025 - IPC C05D9/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, namely to methods of producing liquid complex chelate microfertilizers based on chelate complexes of essential microelements of cobalt, iron, copper, zinc, manganese, boron, molybdenum. Method includes two stages: at the first stage, weighed portions of 0.174–5.603 g of disodium salt of ethylenediaminetetraacetic acid of Trilon B and 0.107–3.430 g of oxyethylidene diphosphonic acid are prepared and dissolved in distilled water. At the second stage, weighed portions are added in amount of 0.1–1 g of CoSO₄ ⋅ 7H₂O, 0.05–2.5 g of FeSO₄ ⋅ 7H₂O, 0.039–0.39 g of CuSO₄ ⋅ 5H₂O, 0.004–0.044 g of ZnSO₄ ⋅ 7H₂O, 0.044–0.44 g of MnSO₄ ⋅ 5H₂O, 0.0056–0.056 g of H₃BO₃, 0.002–0.02 g of (NH₄)₂MoO₄, mechanically stirring on a magnetic mixer for 1 hour at a constant rate of 120 rpm at the boiling point of the water bath. Finished product is poured into containers.

EFFECT: enabling binding of essential trace elements boron and molybdenum due to simultaneous use of two chelators.
