The results of 23 years of winter wheat, barley and potato intensive systems of protection tested in a stationary field plot experiment showed that typical for Belarus soddy-podzolic medium loamy soils are of rather a high ability to inactivate different chemical class pesticides, as a result there was no preparation residue accumulation in the soil, no essential vertical migration of pesticides trough the soil profile, and pesticide residue accumulation in the studied crop yield. The changes in soil microflora quantitative and qualitative composition and also soil biochemical activity against a background of a long-term pesticide application were not essential and of temporal character. So, by strict observation the rules of plant protection product application, the ecological risk is minimized.
