Agricultural Cenosis Pollution by Heavy Metals from Past Ecological Damage Objects

Parameters of heavy metals (accumulated in objects with past environmental damage, e.g. unauthorized dumps of municipal wastes, sludge deposits from treatment facilities, and reclaimed quarries) distribution in soddy podzolic soils’ agrocenosis have been studied in this paper. Negative changes of soils’ properties for the lands, periodically experiencing contamination from the objects with past environmental damage have been characterized. In the conditions of minimization of mechanical impact on soil, a negative trend in soil properties changing on the adjacent to objects with past environmental damage lands at preservation of uncontaminated automorphic analogs has been tracked. Agrocenosis degradation indicators are substantially defined by past ecological damage objects’ specifics.
