Detoriation of water conditions in the peat soils are closely related to the transformations that take place in the structure of organic soil mass. Changes in water relations together with an increased access of air enable various physical, chemical and biological processes to take place. This, in turn, leads to changes in organic soil mass and soil mass transformation into moorsh. The scope of changes and their rate depends also on the properties of the original materials. Amorphic peats are most susceptible to secondary tranformations, whereas fibrous peats undergo moorsing slower. peat formations after secondary transformations have been divided into 5 groupsassuming numerical values of water absorptivity as the basic for the division. This index expresses the ratio between the lowest water absorptivity of a given formation to its absorptivity in the fresh state.The aim of the present work was to evaluate in what way type of moorsh and degree of its secondary transformation influence some of its physical properties, i.e., retention curves and water conductivity, absorption level (wetting) and desorption (drying) of steam as well as its specific surface area. The study object included peaty moorshes and proper moorshs originating from peats formations at various stages of decomposition. The soil material originated from the region of Polesie Lubelskie.
