FIELD: fertilizers, biotechnology.
SUBSTANCE: invention relates, in particular, to technology for preparing biofertilizers. 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. Cattle 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, subjected for autoclaving at 0.8-1.2 atm for 45-75 min followed by addition of microorganisms able for associative nitrogen fixation taken in the concentration 108-1010 cells per 1 g of the preparation. 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 for preparing and decreasing time for preparing the preparation.
EFFECT: improved preparing method.
