FIELD: agriculture.
SUBSTANCE: initial raw materials - peat - are cleaned and ground, treated with an alkaline extractant while mixing. Produced peat-and-water mass is exposed to activation by at least one grinding, when physical-chemical decay of peat activates. In humin product produced after grinding the content of humates in % (on a dry basis) makes at least 50%. Grinding is preferably made in an auger and/or ultrasonic grinder.
EFFECT: invention makes it possible to accelerate and stabilise process of humin substances extraction due to activation of physical and chemical reactions.
