Abstract
Mountain forest soils in the region of the Jizera Mountains are polluted by acidification. These soils have a poor quality of humussubstances, are highly acidic throughout the whole profile and the main substance bound in the soil sorption complex is aluminum.This study monitors what effect have the consequences of natural processes and human activities on properties of soils that develop close together and therefore are exposed to the same negative effects, covered by the same vegetation, but are situated on bedrockswith different properties.
The study only partially confirmed the assumption that the soils developed on alkaline parent rock have better quality than the soils on acid parent rock. It can be concluded that the soils on alkaline bedrock are in most aspects of better quality.
