FIELD: fertilizers.
SUBSTANCE: invention relates to preparing the complex organomineral fertilizer. Manure is stored to clamps, heated preliminary and anaerobic fermentation is carried out. After heating manure to 75-80oC by layers bischofite brine of sulfate type of the formula MgCl2·6H2O with molecular mass 203.303 Da is added to clamp for cooling treated mass to fermentation temperature 53-55oC. Brine is added by layers under pressure 0.03-0.08 MPa with consumption 100-200 l per one ton of manure and layers are placed by stratum horizontally with mutual removing 0.3-0.5 cm wherein each ton of organic fertilizer is mixed with 700-800 kg of licorice root and rhizome grist. Prepared organic fertilizer is saturated with trace elements and macroelements with improved physical-chemical indices of fertilizer and vegetable licorice fibers reduce processes of soil erosion also.
EFFECT: improved preparing method.
