ROWTH PROMOTERS OF MICROBIAL ORIGIN COMMON IN POULTRY MANURE

Abstract

Composting is the most economically and environmentally sound technology among the poultry waste disposal methods presented today. The addition of effective microorganisms helps to not only reduce the compost maturation period but also to further positively affect the growth, development, and nutrition of plants, thus improving the process of poultry manure composting. In this article, we isolated and studied microorganisms from fresh broiler manure. The study identifiesthat fresh broiler manure contains from 3,468.0 thousand CFU/ml to 9,446.0 thousand CFU/ml of microorganisms, which use mineral forms of nitrogen. The number of actinomycetes did not exceed 1,434.0 thousand CFU/ml in broiler manure, which shows broiler manure is rich in organic nitrogen. Seed treatment of wheat with metabolites of some strains enhanced seed germination by 10-17% and contributed to an increase in root length by more than 50% compared with the control.Screening resulted in the isolation of microbial strains possessing a highwheat growth-promoting ability. Promising microbial strains of wheat growth promoters PM 88B, PM 93B, PM 90B, PM 80B, and PM 86B are deposited in the State Collection of Microorganisms of the Republic of Kazakhstan for the creation of biological products used for agricultural needs.
