The research was conducted on deposol and rekultisol (technosols) in lignite mine Stanari. The main task of the formed grasslands is to improve the mechanical, chemical and biological properties of the rekultisol and deposol in the reclamation process. The fertility of Stanari deposol is extremely low in comparison to the natural soil. Grassland seeding through direct type of reclamation was conducted in 2008, 2011 and 2012 year. The conducted researches include the changes in the adsorption complex in the surface layer of the treated deposol in the reclamation process. Laboratory analysis of this technogenic soil were carried out before the reclamation and sowing started, and then in the process of reclamation at the end of 2012. On the experimental plots where reclamation measures were implemented, there is a slight improvement in most of the chemical characteristics of the rekultisol. Adsorption capacity and saturation degree of base cations in rekultisol were increased. Proper selection of the agromeliorative and other measures is required in the reclamation process. Well based seeding grasslands contribute to the creation of quality rekultisol.
