Abstract

The aim of this study was to explain and improve the understanding of the specific consistence of the fragipan horizon in moderately humid climate on the example of Albeluvisols of the Carpathian Foothills in Poland basing on mineral and chemical composition of bridges linking coarse soil material. Quantitative X-ray diffraction shows that the studied fragipan horizon contains high concentration of swelling clay minerals. Soil material from the fragipan horizon exhibits numerous clay and iron-clay coatings and clay infillings indicating translocation of colloidal clay and iron oxides from overlying horizons. In addition, bridges between coarse grains of the soil material occur. It is highlighted that swelling clays are responsible for reversible cementation of the fragipan horizon. The clay minerals are major bonding agents and are responsible for brittleness and more friable consistence of the pan in the moist state
