“…Urban soils are mainly contaminated with Pb, Zn, Ni, Mn, Ba, As, Hg, Mo, Cr, Sr, V, Ni, Cr, Co, Cu, F, Al, Li, Be, Ag , Ti, Cd, Se, Sn, Tl, Bi, Na, K, S, Cl, petroleum products etc, as a result of the increase in the number of industrial enterprises over the years [6]. Soil and vegetation cover around metallurgical plants are primarily damaged, with increased aerotechnogenic pollutants not only affecting the upper organic part of the soil, but also the lower mineral layers [7]. When all samples found above-average amounts of environmentally harmful heavy metals in the soil, surface and groundwater of the iron and steel industry, this was due to the unsatisfactory ferrous metallurgy and environmental conditions.…”

The article describes the man-made degradation of irrigated soils, resulting from chemical pollution, changes in soil chemistry, and heavy metal pollution during thermal power plant operation. According to the results, the pH value of the soil fell from 7.2 to 6.1 as a result of man-made degradation, ie the acidic environment increased as a result of pollution. Also, some heavy metals, including As - increased by 4.2 times, Cr - by 16 times, Ni - by 2.5 times, Rb - by 3.7 times, Zn - by 4.8 times. Changes in soil environment and soil ecological status have resulted in deterioration in fertility rates and negatively impacted crop yields and quality.
