The territory of the Republic of Kalmykia includes three soil zones, completely different in their physicochemical, chemical and biological properties. In the present work, an attempt was made to carry out a comparative analysis of the chemical and biological properties of soils in Kalmykia. Zonal soils of the Republic of Kalmykia were chosen as objects of study. Laboratory and analytical studies, as well as sampling, were carried out using methods generally accepted in biology and soil science. During the laboratory experiment, it was found that the most favorable conditions for the growth and development of radishes were found on the southern chernozem, followed by light chestnut and brown semi-desert soil. On the soils of the oil field, the growth of radish is significantly inhibited, on the contrary, on the soils of the reserve it is stimulated. As a result of the research, it was found that the soils of Kalmykia, according to the activity of soil enzymes, form the following series of southern chernozem > light chestnut > brown semi-desert. According to the availability of macroelements, the soils of Kalmykia form a similar series. The biological properties of southern chernozem, light chestnut and brown semidesert soils differ significantly, which is probably due to the availability of biophilic elements available to plants and their granulometric composition, and anthropogenic or recreational impacts also affect biological properties. |
