Acta Agrophysica

2001

tom 50

The aim of this study was to analyse the acidity and buffer abilities of selected soils occurring within terrestrial (forest, arable and meadow) ecosystems, under specific form of protection within the Lasy Janowskie Landscape Park. The results of the study indicate that the very acid and acid reaction of the soil environment is the result of natural processes, such as relations between mother rock and plant cover (low pH, high value of hydrolytic and exchangeable acidity, and high content of mobile aluminum), and low degree of saturation of the sorption complex with bases. The greatest buffering abilities showed typic gley soil (Dystric Gleysol), peat soil (Terric Histosol), and accumulation horizons of other soil types.
