METHOD FOR PREPARING COMBINED BACTERIAL FERTILIZER FOR PLANTS Russian patent published in 2006 - IPC C05F11/08 C05G3/04 C12N1/20 

FIELD: fertilizers, agricultural biotechnology.

SUBSTANCE: method involves vermicomposting of organic waste by using hybrid of red California worm with earthworm of the natural Kuban population taken in the amount 10⁴ worms per m². Agriculture animal manure neutralized preliminary to pH 7-8 is used as organic waste. Vermicomposting process is carried out for 2-3 months at temperature 16-32°C in natural conditions and after separation of worms from biohumus on vibrating screen with pore size 0.5-1.0 cm, then biohumus is dried up to moisture 50-60%, packaged into polypropylene packets and subjected for autoclaving at 0.8-1.2 atm for 45-75 min followed by addition of microorganisms relating to genus Rhizobium and Agrobacterium and kept up to the titer value 8 x 10¹². Invention provides expanding assortment of microbiological fertilizers, enhancing their biological activity due to increasing viability of microorganisms, reducing material consumptions in producing based on simplifying technology of their preparing and decreasing time in preparing the preparation.

EFFECT: improved preparing method.
