Coal mining practices reduce the microbial biomass ...The coal mining process followed by the soil construction usually reduces the SOM, which can facilitate the soil degradation. The loss of SOM and, consequently, the decrease of the microbial population, affect the soil's physical restoration as well as the re-vegetation process (Grayston et al., 2004). The SOM, the microorganisms, and the ...
