Water, physical and physical-mechanical characteristics of the vertisols were investigated on seven soil profiles in the in the central part of the Republic of Macedonia (Štip, Probištip and Ovče Pole valleys). The investigated vertisols show very unfavorable water, physical and physical-mechanical characteristics, which obstruct the usage of these soils. In spite of the high water preservation, plants in these soils are not provided with enough water because available water capacity is 12.32 mass %, or only 38 mass % of the whole moisture which is retained in the soil is available to plants. The retention curves are relatively close one to another. The greatest decline of the curves occurs at lower pressures. In dry sieving of the soil the aggregate fraction >10 mm is dominating (average 56.56%), which in the same time shows the lowest stability in water. That kind of structure makes these soils hard for tiling. The investigated samples of vertisols are highly plastic, with the plasticity index higher than 17, which significantly shorten the physical suitability of soil for tillage.
