The reclamation of slope lands for agricultural use requires a variety of precautions with the aim to prevent soil erosion. One of the methods used in achieving this aim is creating of gradient steep narrow terraces. This enginneer - technical method has high antierosion efficiency. When land used for agricultural purposes is restored, terraces must be preserved. It is known that the natural soil profiles are destroyed in the process of terracing. Such destruction as in terracing takes place when soil horizons or parts of them are removed in buiding construction, meliorative technologies as building platforms levelling, at irrigated areas etc. The erosion degrees are a typical example of removal of humus layer to different depths. As a whole, the technological destruction of soil profiles is not the result of any natural event. The aim of this investigation is the study of some water and physical properties of the soil on gradient steep narrow terraces (canal terraces on a brodbase); soils, with mechanically (artificially) removed soil horizons to a different depth as well as soils with different degree of erosion (slight, medium and strong).
