BIOLOGICALLY ACTIVE ORGANO-MINERAL COMPLEX AND A METHOD FOR PRODUCTION THEREOF Russian patent published in 2019 - IPC C05F11/02 

FIELD: agriculture.

SUBSTANCE: invention relates to the agriculture. Biologically active organo-mineral complex is made of a humate-containing substance – peat and contains elements of mineral nutrition of plants and microelements. Ammonium nitrate NH₄NO₃ is introduced into the composition of the complex as ammonium nitrate component with following ratio of components, wt %: dry peat – 4.9, potassium hydroxide KOH -12.4, orthophosphoric acid H₃RO₄ – 12.4, ammonium nitrate NH₄NO₃ – 9.1, boron H₃VO₃ – 0.113 molybdenum (NH₄)₆Mo₇O₂₄ – 0.034, manganese KMnO₄ – 0.053, water H₂O – 61. Invention also relates to a method of producing a biologically active organo-mineral complex. Cavitational dispersion of ground peat is carried out with water at a ratio of peat: water equal to 1:10. Potassium hydroxide is added to the obtained suspension at ratio of 1:2.5, and hydrolysis of the mixture is carried out in reactor for 20 minutes with continuous mixing. Then the alkaline mixture is heated in a water bath for 1–1.5 hours at 65–80 °C and passed through a flow chamber of an ultrasonic disperser at rate of 0.3 liters per minute. After that, the hot mixture is neutralized with continuous stirring with orthophosphoric acid, diluted with water in ratio of 1:1, to pH of the mixture equal to 7.0–7.5. Ammonium nitrate is added to the mixture in amount of 9.1 %, with the ratio NH₄NO₃: dry peat equal to 1:1.9, and microelements. Mixture is filtered through polymer screens with cell diameter of 100 mcm to obtain finished product.

EFFECT: technical result is increase of crop capacity and product quality.
