Resumen
The rocks of the Nikopol manganese ore basin in the southeast part of Ukraine are presented the holocene, postpliocene, neogen and paleogen deposits. Taken on day surface they are problem for environment management for the future. The reclamation of disturbed land is conducted in one technological cycle with the process of manganese ore mining. The soil mass is taken off, piled up and heaped onto the land after the rock has been replaced. The effectiveness of different models of land reclamation and heavy metals migration through rocksoil- plant system was researched. It was established the rocks getting on the day Surface after manganese ore mining and plant melioration stages pass in other geochemical conditions and change their physical-chemical properties. The physical-chemical investigation of the organic substances formation particularities were done. It is determined the humic asids level is dicreased according to black soil to 10 times. It was established also, phytomeliorated rocks had the differences in a low correlation of the humic and fulvoacids (0.2-0.5).20 year rocks plant melioration led to humus rising 5-8 times.
