FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. Method for humification vegetable raw materials consists in that a batch of initial vegetable material - common pine bark - is subjected to mechanochemical treatment in an aqueous solution of potassium hydroxide with concentration of 0.5 mol/l in a rotary cavitation apparatus with rotor frequency 3,000 rpm, where hydrodynamic action on mixture during 25 minutes at a temperature of 60 °C and hydromodulus 1:50, then liquid phase is separated by centrifugation and humic acids from liquid phase when acidified with mineral acid to pH 2.
EFFECT: invention provides a high-quality product.
