Abstract
Issues of environmental assessment of the soil microbiological state in the zones of industrial poultry management are relevant and important for predicting further changes in the biosphere under the influence of technogenesis. The aim of the study was to identify the features of formation of soil microbiocenosis in the zone of broiler production by microbiological indices and phytotoxic effect. Microbiological studies of soil were carried out by standards methods of soil microbiology, soil toxicity and phytotoxic effects were calculated. The results of microbiological analyzes showed that there is a change in the quantitative structure of the soil microbial cenosis, depending on the location of the contamination. The maximum total number of soil microorganisms was in control, non-contaminated area. The minimum number of organotrophs is evidence of significant inhibition of microorganisms under the influence of toxic substances of waste filtrate. At the same time was changing the composition of the spore microbiota, most of it observed in the soil polluted of metabolites of the slaughterhouse waste and contaminated with filtrate from the poultry. Increase of micromycetes due to the entry into the soil of the remains of litter from sawdust, leads to activation of cellulose-destroying microbiota. Also, in contaminated variants, as compared to control, the number of oligotrophs that can develop on depleted soils increases. The number of pedotrophs decreases, which is evidence of a decrease in nutrients in the soil.
