Intensity of Soil Pollution by Toxic Substances Depending on the Degree of Its Washout

A significant degree of ploughness agricultural lands Ukraine has led to increased erosion and the creation soils varying degrees washout, which leads dehumification contamination with toxic substances. Therefore, purpose study was establish features horizontal migration accumulation heavy metals lead, cadmium, copper, zinc, trace elements boron manganese, radionuclides caesium strontium on podzolic loamy chernozems washout: non-eroded, weak medium conditioned by development processes. During study, spectrophotometric, colorimetric, gamma-spectrometric, radiochemical methods were used determine content substances in soil. The results showed that slightly washed soils, humus is 12.9% less, easily hydrolysed nitrogen – 13.3%, mobile forms phosphorus 51.1%, potassium 34.9% less than soils. medium-washed soil 8.8% lightly soil, 14.3% 15.3% more, 42.9% more. strong lead chernozem established, increases increasing washout 24% more non-eroded same dependence established zinc their predominance 17 %, compared non-washed. copper lower non 5%, 18.8% non-washed medium-washed, manganese 3.3% from It also found concentration decreased 25.6% ones
