Enhanced soil fertility, plant growth promotion and microbial enzymatic activities of vermicomposted fly ash

Abstract It is reported that coal consumption in the Asia-Pacific region is going to increase to about 87.2 percent by 2035. Management of coal combustion residues (CCRs) generated by industries is a major bottleneck towards handling the repercussions of coal usage. The present study investigates a...
