FIELD: agriculture.
SUBSTANCE: concentrate of humic compounds obtained from peat, for the preparation of biostimulating humic preparations, is characterized by that it contains fulvic and humic acids in a percentage ratio of 70:30, which are obtained from lowland peat with a decomposition degree of 20-30%, with moisture of not more than 25% and ash content of not more than 25%, subjected to mechanical and chemical treatment in a rotary reactor-mixer at rotor speed of 2500-3000 rpm for 30 minutes with the addition of potassium hydroxide (KOH) or sodium hydroxide (NaOH) in amount of 0.1-0.2% of the mass of the used peat, with the following corresponding mass ratio of these components of 1000:1-500:1.
EFFECT: invention increases output of humic compounds.
