METHOD OF PREPARING COMPOST Russian patent published in 2011 - IPC C05F3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to agriculture and can be used to produce biologically active organic fertilisers. The method involves mixing organic wastes with crushed moisture-absorbing material, feeding the obtained mixture into a fermenter and aerobic composting. The mixture is unloaded into the ground right after maximum temperature begins to drop. Further, the mixture is mixed with an inoculating additive in amount of 2-7% of the compost mass and held in piles for 30 days. The inoculating additive used is a suspension of manure-containing waste water with recirculating sludge from pig-breeding enterprises, which contains a biocenosis of microorganisms Rhodococcus, Alkaligenes, Pseudomonas, Baccilus, Mycrococcus, Arthobacter, Mycobacterium, Aureobacterium, Corynobacterium, Nocardia. The technical result is reducing total loss of nitrogen and organic substance when composting.

EFFECT: method enables to obtain compost capable of increasing yield of agricultural crops, lowering accessibility of heavy metals to plants, suppressing phytopathogenic microorganisms and reducing content of trace concentrations of halogenated doxins in soil.
