Effect of cadmium on agrochemical and ecological status of irrigated soils

The sources of environmental pollution with heavy metals are mainly wastes of the metal production industry, combustion products of various fuels, car fumes and exhaust gases, chemicals used in agriculture, etc. The use of coal, oil, gas and a number of other fuels is increasing day by day, which pollutes the environment several times more than the metal production industry. Also, heavy metals enter the soil with biocides and mineral fertilizers, and soil contamination with heavy metals accumulates in the human body along the food chain and causes various diseases. In Uzbekistan, serious attention is being paid to the issues of ensuring ecological stability, creating the necessary conditions for the population to have a comfortable natural environment, rational and effective use of natural resources, preventing emerging environmental problems and eliminating their negative consequences. This article presents the accumulation of cadmium element in the takyr-meadow and meadow soils of Kashkadarya region, Kasbi district, exceeding the permissible standards.
