FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, to the field of chemical peat processing. Method of producing complex liquid humic fertilizers from peat involves subjecting the material – top, lowland or transition peat – to mechanochemical treatment in aqueous ammonia solution with concentration of 1.0 mol/l or in a solution of potassium hydroxide with concentration of 0.5 mol/l in hydrodynamic cavitation apparatus with rotor rpm of 3,000 rpm. Treatment is carried out at temperature of 10–60 °C and hydromodulus of liquid phase 1:50 for 5 or 10 minutes respectively. Then liquid phase is separated by settling with subsequent centrifugation and neutralized obtained aqueous-alkaline solution of humic acids with solid potassium monophosphate to pH 10.
EFFECT: invention provides intensification of the process of alkaline hydrolysis of organic matter of peat material and additional introduction of potassium and phosphorus into the composition of fertilizer.
