PRODUCTION OF ORGANO-MINERAL FERTILIZERS BY BIOCONVERSION OF POULTRY WASTE

Abstract

An urgent problem of the poultry industry of agriculture in the Russian Federation is the protection of the natural environment from pollution by poultry waste. From the point of view of the economic component of the technological process of industrial poultry farming, long-term waste deposition can act as a limiting factor in the issue of scaling up and expanding production. One of such effective practical techniques aimed at solving this problem can be composting or biological conversion, usually carried out with the participation of a complex of microorganisms. The aim of the study is to develop a technology for the bioconversion of organic poultry waste into organo-mineral fertilizers using a complex of microorganisms. For this purpose, it is planned to create a stable complex of microorganisms capable of performing a step-by-step degradation of the used litter and litter mass as the main waste of the industrial poultry industry. The technology involves the isolation and maintenance of cultures of bacteria of the genera Bacillus, Pseudomonas, Cloctridium, Proteus, Lactobacter (complex 1), mycelial cultures of thermophilic fungi of the genus Thelavia and Myceliophthora with pronounced lignocellulase activity (complex 2), as well as cultures of actinomycetes of the genera Nocardia and Cellulomonas (complex 3). The proposed technology will be in demand at enterprises that generate significant amounts of organic waste, in particular, at poultry enterprises. A distinctive feature of the technology will be its reproducibility and relatively low cost with a high effect from the sale of the product.[1] The resulting fertilizers can be used within the production holding that forms the feedstock-organic waste, since the vast majority of such enterprises have a crop production sector for self-sufficiency in feed (closed cycle).
