FIELD: agriculture.SUBSTANCE: method of production of humic preparation comprises crushing peat, mixing it with water, and treatment of water-peat mixture with ultrasound, and the peat crushed to fractions of 200-250 mcm is mixed with water in a ratio of peat/water from 1/6 to 1/10 by weight parts, the resulting mixture is heated to the temperature of 40-60°C, then the first ultrasonic treatment is carried out at a frequency of ultrasonic vibrations of 25-50 kHz for 30-60 minutes, then the resulting product is stirred in a centrifuge at 1500-3000 rev/min for 5-15 minutes, then the product is subjected to repeated ultrasonic treatment in the previous mode, then the product is cooled to room temperature and filtered to a particle size of 50÷100 mcm.EFFECT: invention enables to obtain biologically active humic preparations, most effective, environmentally friendly and physiologically safe for the body of animals and plants.2 cl, 1 tbl, 1 ex |
