ORGANOMINERAL FERTILIZER AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2020 - IPC C05G1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to organomineral fertilizer, which includes dehydrated zeolite with amino acids and/or oligopeptides inserted into its pores with molecular size of not more than 1 nm in amount of 500–1800 g of amino acids and / or oligopeptides per 1 ton of zeolite, with porosity of modified zeolite from 45 to 75 % and size of cavities and channels of zeolite crystals from 0.2 to 1 nm, as well as to a method of producing organo-mineral fertilizer, comprising activating the dehydrated zeolite with an aqueous solution containing amino acids and/or oligopeptides with a molecule size of not more than 1 nm, at ratio of solution volume and amount of zeolite in amount of 500–1800 g of amino acids and/or oligopeptides per 1 ton of zeolite and during heating of zeolite to temperature from 35 to 90 °C.

EFFECT: technical result consists in obtaining organomineral fertilizer, having high efficiency, prolonged action, as well as in possibility of introducing lower doses of fertilizer into soil; fertilizer can be used in planting of agricultural and forestry crops, as well as for cultivation of depleted soil and recultivation of disturbed lands.
