Microbial preparations improve mineral nutrition of plants, protect against phytopathogens, and increase their resistance to stress factors. The aim of our research is to study the effect of microbial preparations on the biological activity of rhizosphere and the productivity of oil flax under no-till in the Crimean Steppe. Microbiological analysis of the rhizosphere of oil flax showed that there is a tendency to increase the number of microorganisms of various ecological and trophic groups both under the conditions of the conventional farming system (CFS) and no-till when seeds are inoculated with a complex of microbial preparations (CMP). Under CFS, the number of microorganisms using mineral forms of nitrogen as nutrition increased by 28 %; pedotrophs – by 37 %; ammonifiers and oligotrophs increased under both farming systems. The total number of nitrogen fixers increased by 29 % under CFS as a result of biological preparations use, while under no-till there was only a trend towards increasing the amount of azotobacter. The number of actinomycetes increased under the influence of CMP by 50% under direct sowing; micromycetes decreased under both farming systems. The number of cellulose-degrading microorganisms increased by 18 and 27 % under no- till and CFS, respectively. The yield of oilseed flax under no-till was 0.11 t/ha (12.9 %) higher than under conventional farming system. On average, over three years (2017-2019), an increase in yield amounted to 0.12 t/ha (19%) due to the use of microbial preparations.

This study was performed to evaluate effects of no-till (NT) and standard tillage (ST) on POM in two 15-ha neighboring fields from 2003 to 2004. We also evaluated the effects of minimum tillage (MT) on POM after both NT and ST fields were converted to MT in the summer of 2005. We quantified C and N stocks of three size fractions (53–250, 250–1000, and 1000–2000 μm) of POM (0–0.15 m depth). The POM-C 53–250 μmand 250–1000 μmfractions decreased by 25% and 36% after six months under ST, whereas relatively little change occurred under NT, suggesting significant tillage effects over the period 2003-2004. Only small changes in POM content then occurred under MT on both fields. Changes in POM-N were similar to POM-C changes upon tillage conversions. This suggests that reduced tillage did not lead to soil C increase compared to ST but may help maintain the level of soil C for a typical California farming system. Short-term, field level variability of POM was primarily affected by tillage and was further influenced by clay content, bulk density, and scale of observation.

Abstract The study of the taxonomic structure of the southern chernozem under influence of microbial preparations and various farming systems in the conditions of the southern steppe zone has been carried out. Metagenomic analysis of the microbiome of southern chernozem showed the presence of 174 genera representatives of prokaryotes, among which 17 are dominant, representing more than 1%. Farming systems cause changes in the taxonomic structure of the microbiome in comparison with virgin soil in the steppe zone. The influence of microbial preparations of complex action on the qualitative and quantitative composition of the microbiome of southern chernozem and increasing under no-till farming system has been established. The maximum content of water-soluble organic matter was found in virgin soil, which has higher amount of plant residues, up to 491 mg/kg of soil. Under the influence of farming systems its amount decreased in 4.2-8.5 times. The use of a complex of microbial preparations in the southern chernozem contributed to an increase in the amount of water-soluble fraction of humus depending on the farming system: 1.7 times with the conventional farming system and 3 times with no-till compared to the control without CMP.

Direct Sowing

Agricultural technologies aimed at reducing the tillage can be adopted as safer farming methods to preserve and improve the diversity of soil microbial communities. The area under the promising resource-saving no-till system (direct sowing) is increase in the conditions of the Steppe annually. The use of herbicides in such a farming system causes a negative effect on the soil biocenosis. But the introduction of agronomically useful microorganisms into the rhizosphere are increasing the resistance of plants against stress factors, their yields and product quality, and preserving soil fertility. The objective of this research was to assess the state of microbiocenosis of southern chernozem under the influence of no-till system and a complex of microbial preparations. The influence of direct sowing and microbial preparations on the state of microbocenosis of southern chernozem was established. The number of cellulolytic microorganisms increased under the influence of farming systems in comparison with the virgin soil. The use of microbial preparations contributed to an increase in the number of microorganisms of ecological and trophic groups and the representation of the majority of phyla, which also depended on the system of agriculture. A decrease in the representation of Acidobacteria and Verrucomicrobia and an increase in Firmicutes and Proteobacteria were observed in comparison with virgin soil.

The Impact

Microorganisms are the most important bioindicators of the environment and ecological risk assessment. The impact of the no-till farming system in combination with microbial preparations needs to be studied and is an urgent task aimed at preserving fertility. The aim of our study was to determine the effect of pre-sowing inoculation with complex microbial preparations (CMP) and farming systems (no-till and conventional farming system) on the microbocenosis of the rhizosphere of Triticum aestivum L. in the Crimean Steppe. Microbiological analysis of the rhizosphere showed a significant increase in the number of actinobacteria (twice). The number of micromycetes, among which there are many pathogens of various plant diseases, decreased under direct sowing by 23 % as a result of inoculation and amounted to 21.5 thousand CFU/g of soil. The number of cellulose-destroying microorganisms that form soil fertility increased under the influence of microbial preparations by 23 % under conventional farming system (10.0 thousand CFU/g of soil); by 20 % under no-till (15.4 thousand CFU/g of soil). Thus, it was found that the use of microbial preparations under both farming techniques contributed to an increase in the number of microorganisms of most ecological-trophic groups that participate in the transformation of nitrogen in the rhizosphere, enhanced enzymatic processes, reduced the development of pathogenic microbiota and, consequently, contributed to improving the state of soil biocenosis.

The purpose of the research was to assess microbocenosis of the southern chernozem under the influence of no-till and microbial preparations. A metagenomic analysis of the southern chernozem revealed 12 phyla, including 11 bacteria and 1 archaeon. The number of cellulolytic microorganisms increased under the influence of farming systems compared to virgin soil. The use of microbial preparations contributed to an increase in the number of microorganisms of ecological-trophic groups and the representation of the majority of phyla, which also depended on the farming system.
