The aim of the work was to reclaim the degraded area using waste sludge obtained from washing excavated gravel and long-term stored (and therefore biologically minimally active) topsoil treated with compost activated by Bacteriolite. In this way, we aimed to return the anthropogenically physically degraded area to a productive state so that, after reclamation, the land (Anthrozem) would achieve a production capacity similar to the arable Fluvisol on the adjacent control plot, with the potential to apply this reclamation method to other degraded locations if successful. Results showed that after one year of remediation, the total carbon content in Anthrozem increased only slightly but significantly; therefore, it is necessary to continue biological measures to increase the organic matter content in the soil. Maize, sown in the area a year after reclamation, achieved a grain yield of 5.1 t ha⁻¹, which nearly reached the three-year average yield in Slovakia for 2022–2024 (6.5 t ha⁻¹).
