The impact of technogenesis on the agricultural landscape contributes to the contamination of all its components by heavy metals. The main measure to protect the environment from the input of heavy metals is the prevention of pollution, which is achieved by improving the technology of agricultural production. The development of methods for the agrochemical rehabilitation of technogenically polluted soil, which ensure the receipt of environmentally safe crop products, is an urgent task. The

It has been experimentally established that the translocation ability of heavy metals and, as a result, the accumulation of toxicants in grain and tilled crops is reduced when using an organomineral fertilizer system. All the studied fertilizer systems reduced the entry of dangerous ecotoxicants - lead and cadmium, into the infiltration water, and also caused the immobilization of Cu and Zn.
