When studying the mobility of heavy metals, a mainly positive role was observed for various fertilizer systems in reducing their content in the acetate-ammonium extractant (pH 4.8). The maximum yield was obtained on the option with the integrated application of lime, organic and mineral fertilizers. On highly contaminated soil, barley grain accumulated 0.98 mg/kg Pb, and 0.18 mg/kg Cd, which exceeds the maximum allowable concentration (MЗC) of these metals in the grain. All applied agrochemical reclamation systems contributed to the reduction of metal intake in plants. The content of copper and zinc in the grain did not exceed the MAC.
