Reclamation of coalmine overburden dump through environmental friendly method.

Coal mine spoils (-the previous overburden of coal seams, inevitable by-product in the mining process) which are usually unfavorable for plant growth have different properties according to dumping years. The reclamation of overburden dumps (OBDs) through plantation by using efficient microbes with suitable bio-inoculants is an environmental friendly microbial technique for significant improvement in fertility status and biological activities of the OBD soil. A systematic greenhouse pot experiment program followed by field trial was conducted to investigate the influence of arbuscular mycorrhizal (AM) and NFB on the performance of plant growth which have resulted in the development of environmental friendly bio-inoculant package for soil reclamation of abandoned mine land by revegetation.
