The study on Orthic Luvisols developed from loess were conducted on a field belonging to an experimental farm in the Lublin Upland (Poland). The objective of the study was to determine the spatial differentiation in the granulometric composition, humus content, and the physical properties of the soil as a result of erosion. Detailed mapping showed a mosaictype variability in non-eroded soils, in soils of various classes of erosion, and in depositional soils on watershed areas and on slopes. Slight and moderate classes of soil erosion resulted in a deterioration in the soil properties under study. Further erosion was accompanied by a gradual improvement in the properties of the soils, attaining levels similar to those of non-eroded soils. The depositional soils also had favourable physical properties. The location of the soils over various forms of the terrain studied had a less pronounced effect on the differentiation in their properties than was in the case of class erosion.
