Opis:: 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.

Opis:: Up-to-date studies on erosion, including erosion on loessial soils, are based on the division of an actual topographic surface into three zones assumed a 'priori': top area, eroded slope area and foot-hill area as depositional area. As the main research method for the field survey the soil-levelling cross-section has been used most frequently. Although this method allowed us to introduce erosion protection measures in the form of antierosion fields, however, these measures did not work properly in practice because of two reasons: 1) insufficient recognition of the soil cover variability on the basis of soil-levelling cross-sections for establishing the agroecological zones, and 2) basing the analysis of erosion effects mainly on the course of chemical properties. A new approach, described in this paper, evaluates the soils in the eroded loessial region also on the basis of their physical properties. A point valorization scale was developed basing on eight physical and two chemical features of the eroded soils. Computed synthetic valorization indices allow us to classify the uneroded, totally eroded or deluvial soils into the category of good soils, while those being slightly, moderately or severely eroded are classified as medium quality soils.
