METHOD OF PRODUCING CONCENTRATE OF HUMIC COMPOUNDS FROM PEAT FOR PRODUCING BIOSTIMULATING HUMIC PREPARATIONS Russian patent published in 2025 - IPC C05F11/02 C05G3/00 A01N61/00 

FIELD: agriculture.

SUBSTANCE: method of producing concentrate of humic compounds from peat for producing biostimulating humic preparations is characterized by that it involves using lowland peat, sieving and grinding on a vibrating sieve to particle size of not more than 5-6 mm, feeding it into a mixing reactor for mechanical-chemical treatment and adding an alkaline reagent – potassium hydroxide (POH) or sodium hydroxide (NaOH), wherein peat with a decomposition degree of 20-30%, with a moisture content of not more than 25% and an ash content of not more than 25% is used and mixed in a rotary mixing reactor at rotor speed of 2500-3000 rpm for 30 minutes with alkaline agent potassium hydroxide (KOH) or sodium hydroxide (NaOH) in amount of 0.1-0.2% of weight of used peat, at the following corresponding ratio of the masses of components 1000:1-500:1 and a concentrate of humic compounds containing fulvic and humic acids in a percentage ratio of 70:30 is obtained.

EFFECT: invention increases output of humic compounds.
