Variations in Acidity and Cation Exchange Properties of Forest Soils under the Impact of Acid Atmospheric Precipitation

The complex character of variations in acidity and cation exchange properties of forest podzols under the impact of atmospheric emissions from the Pechenganikel’ plant in the Kola Peninsula was revealed using correlation and regression analyses. The high level of acidity and the depletion of the upper horizons in exchangeable bases attest for the anthropogenic acidification of podzols in the affected zone of the plant.
