The role of pesticides in modern agriculture is not in doubt; the continuous improvement of drugs and technologies for their use reduces the possibility of environmental pollution and their accumulation in manufactured products. The purpose of the research is to assess the pollution of the soil cover of agricultural land with residual amounts of pesticides in the Samara region conditions. Tasks: to analyze the content of insectoacaricides and herbicides residual amounts in the soil in the spring and autumn; - establish patterns of residual pesticides migration along the soil profile. As a result of studies conducted in 2016-2018. it was found that the content of total DDT related to the first hazard class in the studied samples decreases, a similar situation is observed for organochlorine insectoacaricides HCH and HCB, their residual amounts were found in the soil in the autumn and spring periods of 2016. Residual quantities of the organophosphorus insect metacosacaricide were detected annually (the exception was the autumn period of 2017). Regarding the content of residual amounts of herbicides in the soil (2, 4-D, dalapon, simazine, atrazine, promethrin, trifluralin, THAN), it can be noted that during the years of research their content was mainly reduced. A study of the pesticides vertical migration showed that the content of their residual amounts in the soil increases with depth, reaching a maximum at a depth of 1.0-1.6 m.
