The work under the conditions of the micropark experience analyzes the impact of the method of application of mineral wool and various reclamation methods for the physicochemical changes in the soilless track devastated by mining sulfur. Our results showed that the tested waste, as well as its manner of application to the soil, had a positive influence on the physical and chemical properties of degraded soils. The most beneficial impact was recorded in the conditions of association of the mineral wool in the top layer of the soil (0–25 cm) of the sewage sludge.
