METHOD FOR PREPARING BIOHUMUS-BASE BACTERIAL FERTILIZER

摘要

FIELD: fertilizers, agricultural biotechnology.;SUBSTANCE: method involves vermicomposting of organic waste by using hybrid of red California worms 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 16-32C 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%, packed into polypropylene packets, corn extract is added in the amount 2.0-4.0% of the biohumus mass, subjected to autoclaving at 0.8-1.2 atm for 45-75 min followed by addition of microorganisms of genus Rhizobium japonicum. 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 fertilizer and decreasing time for preparing the preparation.;EFFECT: improved preparing method.;3 tbl, 4 ex
