METHOD FOR PREPARING BIOHUMUS-BASE MICROBIOLOGICAL FERTILIZER Russian patent published in 2006 - IPC C05F11/08 C05G3/04 C12N1/20 

FIELD: fertilizers, agricultural biotechnology.

SUBSTANCE: invention relates, in particular, to technology for preparing biological fertilizers. 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 is carried out for 2-3 months at temperature 16-32°C under natural conditions, and after separation of worms from humus on vibrating screen with pores size 0.5-1.0 cm then biohumus is dried up to moisture 50-60%, packaged into polypropylene packets, corn extract is added in the amount 1.0-5.0% of the biohumus mass and subjected for autoclaving at 0.8-1.2 atm for 45-75 min followed by addition of the strain Bacillus megaterium var. phosphaticum 319 and kept up to the titer value 8 x 10¹⁰. Invention provides expanding assortment of microbiological fertilizers, enhancing their biological activity due to increasing viability of microorganisms, decreasing material consumptions in producing based on simplifying technology in preparing and decreasing time for preparing the preparation.

EFFECT: improved preparing method.
