The study aimed to evaluate the effect of soil use in the Młoszowa and Bolęcin villages on the species composition of the overgrown vegetation. Additionally, the study compared the chemical and physical properties of the soils that were not being used for agriculture. The soils of Młoszowa and Bolęcin villages did not exceed the permissible concentrations of copper, lead, and zinc, as outlined by the national regulations in [Journal of Laws 2016], for agricultural land. In Młoszowa, the concentration of cadmium exceeded the limit values as per national regulations in [Journal of Laws 2016] for agriculturally utilised land (land group II-2) (<3 g•10-3•kg-1DM). The set-aside of both villages consisted of typical species found in the ruderal areas, fresh grassland and thermophilous species. The granulometric composition of the soils, mainly their silt and sand content, were the primary factors that impacted the species composition of the vegetation of the set-aside. Ruderal and thermophilous species were discovered in the set-aside areas, included those typical of these habitats. The occurring ruderal plants typical of post-mining heaps and post-industrial areas, including hemicryptophytes, testify to the long-term process of fallowing and adaptation to the existing ecosystem with a predominance of the most common species.
