METHOD FOR OBTAINING LIQUID HUMIC FERTILIZER Russian patent published in 2005 - IPC

FIELD: agriculture, production of fertilizers.

SUBSTANCE: the present innovation deals with manufacturing ecologically pure complex fertilizers out of humate-containing raw material. It includes the following stages: preparing an aqueous suspension of humate-containing raw material, the peat, also, suspension should be supplemented with a substance as the source of plant's nutritive elements, then comes treatment of the mixture obtained with alkaline agent while mixing, storing the suspension and separation of liquid phase. As humate-containing raw material one should additionally apply biohumus and/or sapropel, and/or defecated mud, or their mixture at any ratio, and as a substance - the source of plant's nutritive elements - ash of residues after agricultural production at the quantity to provide the content of potassium in ready-to-use fertilizer being not less than 15 g/l, as for phosphorus - not less than 15 g/l. The method enables to increase the content of humic acids and nutritive elements, simplify the process to obtain the fertilizer and provide its microbiological safety.

EFFECT: higher efficiency of the obtained fertilizer.
