Abstract: Bacterial communities play an important role in maintaining stable functioning of soil ecosystems, participating in decomposition of plant residues, accumulation of organic matter, formation of soil aggregates and in the cycle of nutrients. For agroecosystems, maintaining the diversity of microbiocenosis is especially critical because they are essentially less stable and are dependent on external control. The agricultural practices used today (plowing, application of synthetic fertilizers) can negatively affect the richness and diversity of the soil bacterial communities. The solution to this problem may be the application of alternative farming methods to preserve the structural and functional richness of soil (reduced tillage, conservation tillage, no tillage, organic farming). Data on composition and diversity of soil microbiocenosis are important for further forecasting the impact of agriculture and development of effective methods on preserving and increasing soil fertility. This review presents the results of recent studies on the impact of agriculture on the soil bacterial communities. Attention is mainly paid to the effects of applying inorganic and organic fertilizers on the structure and diversity of soil microbiocenosis; the influence of the farming system (different methods of soil cultivation, organic and traditional systems); the influence of cover crops and crop rotation on the microbial community of agricultural soils.
