Heavy metals accumulation in vegetable crop grown on typical chernozem soils

The article presents agrochemical techniques that reduce the accumulation of heavy metals in vegetable crops, such as potatoes and table beets, when they are cultivated on typical chernozem soils with a heavy loam granulometric composition. The data obtained allowed to conclude that the use of lime, as well as the simultaneous use of lime and manure, reduce the penetration of cadmium in potato tubers by 22 and 18%, respectively. In addition, the use of organic in its pure form reduces the penetration of this element by 8%. The studied cultures absorbed copper, lead and zinc in amounts not exceeding the threshold limit value (TLV), also in plots artificially contaminated with these metals. Heavy metals are more intensely absorbed by the aerial part of potato. During the experiments, it was found that the use of lime, organics, as well as their simultaneous application contributed to a decrease in the studied elements penetration into table beet plants. The increase in the dose of mineral fertilizers doubled positive effect of lower penetration of copper and lead into plants, although the difference was within the experimental error. A double dose of mineral fertilizer did not have any positive effect on the penetration of cadmium and zinc.
