The research was conducted in agriculturally utilized areas. Soil profiles with a cambic horizon were selected for the this study. Main soil properties from individual horizons were analysed using common pedological methods. XRD tests were obtained on a Philips PW 3710 diffractometer. Organic carbon content and nitrogen are higher in the upper part parts of the soil profiles. The distribution of cation exchange capacity within the profile corresponds with the particle size distribution and content of organic carbon. The analysis of the fraction <1 μm showed that the cambic horizon of Haplic Cambisol is dominated - among clay minerals - by illite and also by kaolinite (Humpolec) and by chlorite (Vysoké nad Jizerou). Cambic horizon of Leptic Cambisol has a higher content of kaolinite. The results revealed differences in the formation of the cambic horizon.
