Dovbysh L. Contamination of soddy podzolic soils with heavy metals agroforest landsapes of Polissy.

The object of investigation: farmlands of the Polissya territories of the Zhytomyr region located on the typical for the zone landscapes with derno-podzolic soils, wild and farm crops. Purpose of the researck work: determining the rate of contaminating with heavy metals derno-podsolic soils in different elements of the Zhytomyr Polissya's agrolsndsapes, establishing peculiarities of their vigration in natural and agroecological systems taking into account the influence of forest, shelterbelts as biophysical barriers, ecological evaluation of contaminating the territory. The metods of investigation and apparatus: field, laboratory, physical and chemical analysis of the soil and plants, the atomic and adsorption spectrometer KAC-120. Teoretical and practical result: geochemical migration of heavy metals in the landseape sphere has been discovered; coefficients of biological adsorption of heavy metals by farm and wild plants has been determined. Ecological evaluation of heavy metals' content rate in derno-podzolic soils in agrolandscapes of the Zhytomyr Polissya has been conducted. The fields (sphere) of obstetrick: agricultural.
