ABSTRACT
The effect of open-cost mining for coal on microbial C, N and P in sub-humid tropical forest environment was determined. The mining activities have resulted in 64-98% decline in plant
biomass and 67 to 73% in microbial nutrients in barren spoils. The decline in soil organic matter was 60-84% in these spoils. Revegetation of theses spoils resulted in 9-14 times increase
in plant biomass and 1.5 to 5 times in soil nutrients. Also microbial nutrients increased 2.5 to 3 times in revegetated sports as compared to barren dumps.
Key words : Coal Mining, Forest, Humid, Microbial Biomass, Nutrient Flux.
