METHOD FOR PREPARING BIOHUMUS-BASE BACTERIAL FERTILIZER 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 Kuban natural population taken in the amount 10⁴ worms per m². Agricultural 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 under natural conditions, and after separation of worms from biohumus on vibrating screen with pores size 0.5-1.0 cm then biohumus is dried up to moisture 50-60%, packaged into polypropylene packets, molasses is added in the amount 1.0-3.0% of the biohumus mass, subjected for autoclaving at 0.8-1.2 atm for 45-75 min followed by addition of microorganisms of species Rhizobium japonicum. Invention provides expanding assortment of microbiological fertilizers, enhancing their biological activity, decreasing material consumptions and decreasing time for preparing the preparation.

EFFECT: improved preparing method.
