FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. A method for producing humic growth stimulators comprises grinding humidified natural material, alkali treatment in the presence of urea and environmentally safe chelator - iminodisuccinic acid in the ratio 1:1-5:0.1-2.5, exposure for 6-12 hours under normal conditions and separation of solution containing humic substances from the sludge.
EFFECT: invention makes it possible to increase the concentration of biologically active humic substances that have a clear stimulatory effect on plant growth, in the finished product is completely biodegradable, which can be used as an effective fertilizer without increasing the toxic load on agricultural systems.
