Improving soil ecology when applying bacterial fertilizers

Increasing the yield of spring barley on light chestnut soils of the Volgograd region is possible through the use of microbiological fertilizers that activate the processes of plant growth and development. The influence of the methods of basic tillage and the application of mineral and bacterial fertilizers "Azotovit" and "Phosphatovit" on the content of nitrogen in the soil was studied. The degree of decomposition of the linen cloths was the maximum for deep flat-cutting processing. According to the binary interaction, the best results were obtained on the variant with deep flat-cutting processing with double application of bacterial fertilizers. The introduction of bacterial fertilizers sharply increases the content of azotobacter, and especially when they are applied twice. The lowest toxicity of the soil in barley crops compared to the control was noted on the variant with deep flat-cutting treatment, and the maximum on the variant of dump treatment. The analysis of data on the structure of the crop also indicates the advantage of the variant of deep flat-cutting tillage with double application of microbiological fertilizers. The most cost-effective variants were with double application of bacterial fertilizers on the background of deep flat-cutting tillage. © 2021 IOP Conference Series: Earth and Environmental Science.
