Features of accumulation of heavy metals by wheat in the conditions of the forest-steppe of the Samara Trans-Volga region

The article offers an analysis of the accumulation of heavy metals on grain crops when assessing the level of contamination of chernozem soils of the Samara Trans–Volga region with Cd, Rb, Zn, Cu, Co, Mp elements based on the study of their translocation in the soil-plant system. The revealed patterns allow us to assert that the accumulation of heavy metals in the phytomass of winter wheat is significantly influenced by agroecological growing conditions. The total accumulation of heavy metals during cultivation in the Northern agroecological zone is 1.2-1.5 times higher than in the Central and Southern zones.
