abstract: The aim of the study was to evaluate the quality of Haplic Luvisols developed from loess, subjected to accelerated water erosion, on the basis of some physical, physicochemical and chemical properties of the soils and the yield of winter wheat. The study showed that differentiation of grain yield of winter wheat was conditioned by actual soil moisture, organic C content and content of water-stable soil aggregates of diameter of 0.25-10 mm. Value of the features and grain yield of winter wheat were closely connected with the classes of soil erosion. The highest yields of winter wheat were found on colluvial and non-eroded soils, whilst the lowest on very severely eroded soils. Low yielding of winter wheat on very severely eroded soils was related to water deficiency resulting from the location of the soils on slopes.
