Microbiological Processing of Livestock Waste into Concentrated Organic Fertilizer

Abstract

The results of an experiment on the processing of manure by biofermentation using microbial compositions are presented. The compositions contained bacteria that produce enzymes and biologically active substances that are involved in the decomposition of components of organogenic waste, inhibit the development of pathogenic microbiota, preserve the nutrients of the composted mixture and provide fixation of atmospheric nitrogen. It was shown that treatment of manure with active bacterial strains led to a decrease in the number of microscopic fungi and pathogenic microbiota by 1–2 orders already on the 5th day, stimulation of the decomposition of organic matter, an increase in the total nitrogen content, and a decrease in the phytotoxicity of the processed waste.
