pH gleb różnych pięter klimatycznych w Tatrach Polskich

The pH value of the soil upper horizons from 1600 profiles situated on the various altitudes above sea level has been determined. The statistically significant differences between the medium pH values of the soils of the specified biotopes from the respective climatic belts have been ascertained only in the case of: rendzinas, brown soils and pseudogley soils. Unlike the soils derived from the alkali - weathering rocks, the soils derived from the crystalline rocks do not demonstrate the significant differentiation in consideration of the acidity in relation to the altitude above sea level.
