recultivation

The article is devoted to the study of the prospects of using compost with sewage sludge in the raw material for the recultivation of disturbed lands. A special installation was used for bio-composting, which allowed controlling of the process parameters. The results of bio-indication of composts obtained under different conditions of compositions of the raw material mixture are given. Based on the analysis of the results of bio-indication, the optimal composition of the raw material mixture using "fresh" and "old" sewage sludge is established.

The article deals with the theoretical principles of the biological reclamation of disturbed lands.  The best types of plants to be used for biological reclamation of disturbed lands are determined. The successful experience of biological land reclamation in Ukraine as a result of mining and extraction works is analyzed. The possibility of application of such energy crops as miskanthus, stechigras, poplar, willow and pavlovniy for reclamation of disturbed lands is determined.
