Microbial Biomass Carbon
Soil MBC had significant difference for all species after 25year of restoration from recent dump. Microbial biomass C was found in the range 57– 1480.8 ug C/g soil. MBC showed an increase of 150.31%, 585.92% and 295.97% with increased age of reclamation under Azadirachta indica, Dalbergia sissoo, and Gmelina arborea respectively in surface soil (Table 1). MBC showed the highest value in case ofAzadirachta indica (1468 ug C/g soil) followed by Dalbergia sissoo (1338 ug C/g soil) and Gmelina arborea (1161 ug C/g soil) in surface soil after 25year of reclamation. MBC was higher in the reclaimed than the recent dump (Figure 1). Soil MBC showed an obvious increase in all plantation during the 8th and 25th year of reclamation.
