Chemical Transformations In To Podzolic Soilsinduced By Alkaline And Acidic Emissions In Thernswietokrzyski Region Of Poland

摘要

The present study compares properties of podzolic soils developed from sandy materials overgrown by forests, affected either by alkalizing or acidifying emissions.The study entailed sampling 4 pedons in the vicinity of the Ozarow Cement Plant S.A.and 4 pedons near Rudniki village (within the impact zone of "Osiek" Sulphur Mine and Polaniec Power Plant).Soil samples were analyzed for basic chemicalproper-ties.The study showed significant changes in physicochemical properties of the alkalized podzolic soils：an increase in pH value, in base saturation of the exchange complex, contents of plant available potassium and magnesium, CaCO_3 content in organic and humic horizons and in salinity, and a decrease in organic carbon content and hydrolytic acidity, podzolic soils occurring in areas affected by anthropogenic acidification were characterized by decreased pH value, increased total sulphur and sulfate (S-SO_4) contents, increased hydrolytic and exchangeable acidity, and lowered base saturation of the exchange complex.
