Using the cadastral district of Borský Mikuláš as an example, the paper discusses soil erodibility in the region of Záhorie (western Slovakia). The area of interest belongs to the most affected Slovak regions because its natural and anthropogenic conditions favour the occurrence of wind erosion. The following factors determining the intensity and course of wind erosion are considered: soil properties (texture, compaction), climatic factors (temperature, rainfall), velocity and duration of wind, and anthropogenic factors (ploughed fields, vegetation cover). Equations of soil transport, taking into account the velocity of wind (at a dry soil surface), were developed for four texture classes. It was found that the main factors responsible for wind erosion in the research area are the large proportion (90.1%) of light soils, increased dustiness due to the high velocity and duration of winds, and lower rainfall total than in other regions of Slovakia. Thanks to the cultivated crops that reduce the intensity of wind erosion, not more than 14.9% of arable lands (12.9% of agricultural soils) are threatened by strong erosion. The results of the research may be applied (with minor corrections) to the whole region of Záhorie Lowland.
