The effect of 25 years of fertilizer use in leached chernozem on soil fertility and the accumulation of heavy metals (lead and cadmium) and trace elements (zinc, copper, cobalt, and manganese) was analyzed. The application of insufficient doses of organic fertilizers together with mineral fertilizers tended to acidify the soil. For this reason, the application of mineral fertilizers must be combined with sufficient amounts of organic fertilizers, which will both maintain and increase soil fertility. The prolonged use of fertilizers had no negative effect on the accumulation of trace elements in soil and did not appear to pose the risk of reaching the MAC for Pb and Cd in the next hundred years.
