In course of the long-term research there was studied the geochemical inspection of agro-phyto-coenosis in a zone of functioning of large industrial centre Zhodino (Minsk region, Belarus). As a result of realized research it was revealed that field agro-phyto-coenosis were transformed geochemically – content of Cu, Zr, Cr, Co, Sn, Pb and Ni increased in soils (factor of concentration 1.51-4.81). In soils of meadow agro-phyto-coenosis content of Сu, Zr, Co and Ni increased - concentration factor-1.22-3.82. The high content of heavy metals belonging to hazard classes I and II (Pb, Cu, Cr and Co) in peat soils was conditioned by the accumulation of atmospheric deposition of pollutants due to both high absorption capacity of humified organic matter and redistribution of pollutants with surface (lateral) runoff. Sod-podzolic soils contained fewer heavy metals due to self-cleaning - participation of pollutants in redistribution of elements in natural ecosystems (outflow substances to settlings) and low absorption capacity of arable horizons due to low content of humus. Card-scheme of placing of constant trial platforms of agro-phyto-coenosis was presented. The total content of macro and microelements in soils of constant trial platforms of agro-phyto-coenosis was shown.
