The basic objective of the research was to investigate and determine variations in the physico-chemical properties of the arable layer (Ap) of calcareous soils which belong to the group of lithogenic soils. The above objective was achieved by determining the following physical soil parameters: static and dynamic water resistance of soil aggregates as well as the state of their secondary aggregation following static and dynamic action of water. The above mentioned physico-mechanical properties were determined for wet aggregate models, wet aggregate models subjected to freezing and defreezing and dry "ones", i.e., brought from the appropriate level of moisture to the air-dry state. In order to obtain a comprehensive picture of the properties analysed in the study and their complex evaluation, samples were collected in such a way as to represent the most important and common groups of Rendzinas occurring in Poland. Hence, the material sampled for laboratory analyses developed from various parental rocks.
