PROMISING TECHNOLOGY FOR AEROBIC FERMENTATION OF BY-PRODUCTS FROM AGRICULTURE AND OTHER INDUSTRIES

Abstract

We were tasked with developing a technology for the production of organic fertilizers, which would eliminate the disadvantages of the currently used methods of their production. In addition to theoretical research, we have carried out a lot of work on the experimental study of all methods and the quality of fertilizers obtained, applied the latest tools in research of this type, for example, computer modeling of the dynamic mixing process and a thorough microbiological study of various samples of organic fertilizers and their components. In addition to the above-mentioned research methods, we have applied physical and mathematical modeling and an extensive system of microfield experiments. The work has been carried out for almost 30 years by a large number of scientists and agricultural specialists in various fields: anaerobic fermentation, processing of liquid fraction, bespodstilochny and litter manure and aerobic fermentation. As a result, aerobic fermentation turned out to be more economically profitable in production and highly effective when using its product in agriculture – the soil biological complex (PBK). For example, PBK, when applied to the soil of 6 t/ha, enriches it with 600 kg of organic matter, which is equivalent to the effect of 40 t/ha of traditional compost. The main result of the work was the authors' decision to use the microbiological community as the basis of the whole process as a scientific hypothesis of aerobic fermentation. The developed technology has successfully passed state acceptance tests at 2 machine testing stations and is recommended for use in agriculture. The effectiveness of PBK application has been confirmed in CJSC State Farm named after Lenin" in the research of the Federal Research Center "Nemchinovka" in the fields of the Lipetsk region when growing potatoes by McCain and other farms.
