| Popis: | 40% of the territory of Western Siberia is occupied by solonetzes, used mainly for growing forage grasses. The phytomeliorative effect of yellow sweet clover (cultivated in crop rotation at the Siberian Federal Research Center of Agrobiotechnologies (SFSCA) of the Russian Academy of Sciences (RAS) for 31 years), as well as post crop rotation grassing with a mixture of brome and alfalfa (the mixture was sown after twenty years of crop rotation) on the microflora of medium solonetz was studied. It is shown that the cultivation of phytomeliorants has led to an increase in the representation of classes and orders of bacteria in the microbiome of the medium solonetz, associated with nitrogen fixation and mineralization activity of the soil in relation to nitrogen-containing substances. In the post crop rotation grassing variant, a low bacterization of the soil with Verrucomicrobia and a high, as in virgin soil, Acidobacteria were found. |
