Garbul A. V., Garbul E. A., Makarevich E. V., Litvinova M. Yu., Kozhukhova E. V.

During the research, informative biological indicators of the condition of the soil were identified: biological activity, respiratory rate, phytotoxicity, total microbial number and percentage of soil bacilli. When studying the experimental plots, the dependence of the values of the above indicators on the distance from the source of pollution was revealed. With increasing distance from the highway, biological activity, respiratory rate, total microbial number and percentage of soil bacilli in the soil increase, and phytotoxicity and acidity decrease. Using regression analysis methods, a strong dependence of biochemical indicators on microbiological ones was revealed. It was established that the relationship between biochemical and microbiological indicators of the soil is maintained regardless of the season.

Keywords:roadside area, soil pollution, phytotoxicity, biochemical properties of soil, soil microbiome.
