    Forest reclamation of the soil-less land, connected with opencast lignite mining brings effects exemplified many years after activities carried out during the technical and biological phases. The paper describes the post-mining areas characteristics located near Łęknica in western Poland, covered with Miocene sands, reclaimed in the forest direction, 20 years after the reclamation works. Within its framework, after leveling of the pit heaps plateau and the excavation bottom, slopes surface shaping, neutralization of the ground and start fertilizing, the additional fertilizing differentiating experimental plots of two objects has been done. After the 20 years of soil formation in profiles the following horizons have been observed (of thickness): O (2–3 cm), A (< 1 cm) and Cg (5–10 cm) covering the morphologically and chemically modified C1 horizon (10–30 cm), and the unchanged C2 horizon. There have been noted a tendency to re-acidification of the neutralized soil (to pHKCl 3.5–5.0), and differentiation of the soil surface layers chemistry, to the greatest extent related to the litter level forming. The direction of ground development indicates the possibility of appearance in the coming years a symptoms of the podzolisation process.
