This paper presents an evaluation of the use of drilling tailings in reclamation and development of physical and chemical properties of degraded soils. Composites with drilling wastes and other wastes, useful for the reclamation of degraded soils and their reconstruction in devastated areas, were used in the tests. Comparative objects were anthropogenic soil fertilized with NPK and manure at a dose of 30 Mg/ha + NPK. The research shows that the tested anthropogenic soil was characterized by very poor sorption properties, and especially the composites with the participation of the tested waste improved the described properties. The composite with sewage sludge from ZA Puławy had a more favorable (by approx. 20%) effect on the sorption capacity of the reclaimed anthropogenic soil than the composite with municipal sewage sludge from Lublin. The effect of the tested composites on reducing the hydrolytic acidity of the reclaimed soil was similar, but much more favorable than that of manure. The results of the conducted research confirmed that drilling wastes have environmentally valuable properties, but due to their unbalance, they should not be used alone, but in composites with properly selected other wastes, such as manure or sewage sludge.
