“…The experiments were carried out in three replications. The direction of microbiological processes in the soil was determined by the mineralization-immobilization, oligotrophy, and pedotrophy coefficients (Iutynska, 2017;Romero-Olivares et al, 2017). The statistical analysis was performed by the analysis of variance in Excel and Statistica, version 6.0.…”

In the context of energy and environmental crisis, the search for new substances ensuring the formation of microbial cenosis with a rich composition of agronomically valuable groups of bacteria, the optimal level of humification, and the increase of organic matter in the soil will allow to substantiate innovative environmentally safe types of fertilizers and plant protection under specific soil and climatic conditions. Therefore, the aim of the research was to study the peculiarities of the formation and functioning of microbial cenosis of podzolic chernozem soil and the intensity of soil-biological processes upon application of a mixture of probiotic preparations and concomitant formation water in different concentrations. Different concentrations of concomitant formation water (СFW) and probiotic preparations were applied to the soil in the selected plots, and the soil microbial cenoses of farmland were evaluated in the spring and autumn periods on days 15, 30, and 60 after application of the mixtures. Soil without the application of any substances was considered a control variant. The most effective impact is observed on day 30 after application, there is an activation of microbiological processes on day 15, and a significant decrease is observed on day 60, although higher than the control due to the prolonged action of СFW. It was determined that the best variant of the experiment in both spring and autumn periods to improve the viability of soil microbial cenosis is the option of joint use of СFW at a concentration of 900 L ha-1 and probiotic Sviteco-Agrobiotic-01 diluted in a ratio of 1:10 (dose 100 L ha-1). In particular, the total number of all groups of bacteria in the soil increases with the use of probiotics diluted in a ratio of 1:10 (15-31% compared to control) and is the maximum when using a mixture of СFW at a dose of 900 L ha-1 and 10% probiotic (by 82-102% compared to control). Based on the analysis of the coefficients of mineralization-immobilization, oligotrophy, and pedotrophy, it was found that the application of СFW mixture and probiotic increases the soil nutrient content for different ecological and trophic groups of bacteria, reduces the rate of humus decomposition and creates favorable conditions for the development of soil bacteria.

The aim of the work was to determine the quantitative, qualitative composition and taxonomic structure of the eubacterial complex in the rhizosphere of sugar beet under different fertilizer systems. Microbiological methods were used to determine the content of microorganisms in the rhizosphere of sugar beet. Molecular methods were used to determine taxonomic structure as well as metagenome of the eubacterial complex of microorganisms. In the agrocenosis of sugar beet under different fertilizer systems the representatives of such families were prevailed as Alcaligenaceae, Pseudomonadaceae, Nitrososphaeraceae, Gaiellaceae, Micrococcaceae, Solirubrobacteraceae, Streptomycetaceae, Intrasporangiaceae, Solimonadaceae, Syntrophobacteraceae, Xanthomonadaceae, Enterobacteriaceae, Nocardioidaceae, Hyphomicrobiaceae, Comamonadaceae. It was found that under the biological system of fertilizers the species diversity of soil microbiota increased due to phyla: Alcaligenaceae, Gaiellaceae, Solirubrobacteraceae, Streptomycetaceae, Solimonadaceae, Syntrophobacteraceae, Xanthomonadaceae, Enterobacteriaceae, Nocardioidaceae, Hyphomicrobiaceae, Hyphomicrobiaceae. It was detected that the basis of the eubacterial complex of sugar beet included representatives of phyla Proteobacteria, Actinobacteria, Gemmatimonadetes, Chloroflexi, Acidobacteria, Firmicutes, Planctomycetes, Verrucomicrobia, Bacteroidetes, and the absolute dominants were Proteobacteria – 76.9%, Actinobacteria – 13,4 %.

The of the study was to determine the quantitative, qualitative composition and taxonomic structure of the eubacterial complex in the rhizosphere of winter wheat using different fertilizer systems.Methods.Microbiological methods were used to determine the content of winter microorganisms in the wheat rhizosphere, and molecular taxonomic structure and methane of the eubacterial complex of microorganisms were determined. Results.It was found that among large phyla on the variants of the biological system of winter wheat fertilizer the share of Proteobacteria increased to 80,3%, and the number of Actinobacteria decreased to 12.4% according to the control variant 76,3 and 17,5 %, also similar growth rates were marked on the variant of the ecological fertilizer system. The analysis of families shows that such families as Alcaligenaceae and Pseudomonadaceae were dominant in winter wheat crops with the use of different fertilizer variants. Under the industrial fertilizer system, the share of the family Alcaligenaceae was the highest, but with the application of biological and ecological systems it decreased, while the prevalence of the family Pseudomonadaceae on the contrary – increased. The use of organic fertilizers, compared with mineral, contributed to the formation of a variety of bacteria, so the greatest diversity of prokaryotes according to the Shannon index was in the biological fertilizer system – 4,82, and the least – in the industrial version of winter wheat fertilizer. Conclusions. It was found that in the variant of the biological fertilization system the increase of species diversity was due to the following phyla: Acidobacteria, Actinobacteria, Bacteroidetes, Firmicutes, Proteobacteria, Verrucomicrobia, and in the ecological fertilization system due to such philos as: Actinobacteria, Bacteroidetes, Firmicutes and Proteobac. In general, according to the experiment, the absolute dominants were representatives of bacterial philosProteobacteria – 79,1 %, Actinobacteria – 14,0%.
