HIGHLY CONCENTRATED PLANT NUTRITION IMPROVER Russian patent published in 2019 - IPC C05G3/00 A01N43/00 

FIELD: agriculture.

SUBSTANCE: inventions relate to agriculture. Plant nutrition correctors consist of a polyfunctional high-molecular compound – a matrix containing in the side chain at least two types of functional groups selected from the following row: amide, amine, hydroxyl, carbonyl, lactam, nitrile, sulphonic, phosphonic, wherein the active components comprise at least one of the following macroelements in the following amounts: nitrogen – not less than 10 g/l, potassium in terms of K₂O – not less than 10 g/l, phosphorus in terms of P₂O₅ – not less than 10 g/l or at least one of microelements in following amounts: sulfur in terms of SO₄^2- – not less than 55 g/l, zinc – not less than 15 g/l, boron – not less than 25 g/l, molybdenum – not less than 15 g/l, calcium – not less than 10 g/l, iron – not less than 15.5 g/l, magnesium – not less than 55 g/l, and as a preserving agent selected from group: glutaric aldehyde, 3-iodo-2-propynylbutyl carbamate, 1,3-dimethylol-5,5-dimethylhydantoin, 4,4-dimethyloxazolidine, 2-bromo-2-nitropropane-1,3-diol, methylparaben or its salts, propylparaben or its salts.

EFFECT: inventions allow to create highly concentrated plant nutrition correctors, on a polymer base, which ensure increase in the yield and quality of agricultural products and have a long storage life.
