Abstract: In case of significant technogenic geochemical loads on agricultural landscapes, the issue of ecological forecasting of environmental management is particularly important. Scientific studies of this issue are aimed at establishing the critical values for the components of the ecosystem, the classification of technogenic sources of hazardous substances, levels of soil contamination. This study presents a research to determine the content of heavy metals in the soils of the Ryazan region (Russia) and analyzed the level of their pollution. In the experiments organic, organomineral and mineral fertilizers systems were studied. From 2002 to 2008 were conducted lysimetric experiments on detoxification of elevated pollution of sod-podzol sandy loam soil, and from 2006 to 2008 of podzolized black soil. The participation of the non-ferrous metals plant emissions was detected in the pollution of sod-podzol light in granulometric composition soils with copper of up to 80 mg·kg-1, when the average concentration of Cu in the soil was 38.8 ±6 mg·kg-1. Humification plays a significant role in the formation of soil, its most important properties and characteristics. The saturation of 1 hectare of sown area with organic was slightly different in the experiments, but the intensity of accumulation of humus from the various agrochemical means did not almost differ. The problem of adaptation of plants in the conditions of technogenic environment is of primary importance. Plants have three biobarera against the admission of toxicants, these are the soil – the root – the stem – the reproductive organs. Grain in contaminated soil is environmentally hazardous as the content of Pb is indicated at the level of 0.68, 1.17 mg·kg-1 (MPC 0.5), Cd – 0.27, 0.11 mg·kg-1 (MPC 0.1), Zn – 76 mg·kg-1 (50 MPC). Use of fertilizing systems had a mostly positive effect, but products do not always become environmentally friendly
