MICROBIAL ORGANIC FERTILISER AND PRODUCTION METHODS THEREOF Russian patent published in 2016 - IPC C05F3/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, specifically to technology of producing liquid bioorganic fertiliser. Method for obtaining a liquid bioorganic fertiliser comprises water extraction of mineral nutrients and biologically active substances contained in starting raw material, water insoluble deposit separation, alkaline extraction of humus substances from it, separation of alkaline extract, its neutralisation and association with water extract, preparations must be of organic origin only, water extraction is performed during 1-3 hours at 20-40 °C, starting raw material to extractant ratio is 1:3-1:5; alkaline extraction is performed for 10-16 hours at 20-40 °C, alkaline extract is neutralised with citric acid pH 6.5-7.5, fermentation processes are inhibited with sorbic acid, associated with aqueous extract, mixed, filtered to produce a liquid end product.

EFFECT: invention enables to obtain high yield of environmentally safe products, clean soil from hazardous substances and pathogenic microorganisms, recover soil and reduce chemical load on farmland while reducing power consumption.
