METHOD OF PRODUCING BIOFERTILIZER Russian patent published in 1999 - IPC

FIELD: fertilizers production. SUBSTANCE: substrate based on agricultural and industrial organic wastes is subjected to vermi-composting on a new industrial line with earth-worms obtained by interbreeding of Red California hybrid with Russian earth-worm population Eisenia foetida at 16-24 C for 4-6 months. Resultant biohumus is freed of worms and is advantageously left under natural conditions to be completely ripened. According to invention, immediately after separation of worms or after final ripening of biohumus, microorganisms exhibiting fungicidal activity are added, in particular, Bacterium subtilis stain IPM-215 in concentrations from 1•10⁹ to 1•10¹² spores per 1 kg or culture of micophilic fungus Trichoderma viride Persex S.F.Cray No 16 in concentrations from 1•10⁴ to 1•10⁸ spores per 1 kg of biohumus.
