METHOD OF PRODUCING BIOHUMUS Russian patent published in 2011 - IPC C05F11/08 

FIELD: chemistry.

SUBSTANCE: invention relates to biotechnology and specifically to production of biofertiliser and plant protection agents. The method of producing biohumus involves worm composting of a substrate based on organic agricultural wastes using an industrial line of earthworms Red Californian hybrid and adding a culture of microphilic cellulose-lytic fungus Trichoderma viride. The substrate used is a mixture of peat and cattle straw-containing manure taken in weight ratio of 1:4 and moisture of 75-80%, and the culture of microphilic cellulose-lytic fungus Trichoderma viride is added on cooked wheat grain in amount of 2% of the weight of the substrate 2 weeks before releasing the earthworms in amount of 40 mature adults (30-35) g per kg of the substrate. Worm composting is carried out under cradling conditions for 3-4 weeks at temperature +20…+25°C.

EFFECT: invention enables to obtain biohumus with good protective properties and high growth-stimulating activity.
