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.
