“…Other studies by Shrestha and Lal (2010) also estimated higher C stock than the present study in litter component of reclaimed minesoil of Ohio (USA) in forest ecosystem (3.96 Mg Cha -1 ). In Indian mining conditions (revegetated minespoils of 19 years age, Singrauli, India) C accumulation by litter component was estimated 2.80 Mg C ha -1 @ 0.15 Mg C ha -1 year -1 (Tripathi et al 2014), which is higher than the present study. Studies reported that, with increase age of vegetation C stock in the understorey vegetation and litter fall also increases (Amichev et al 2008;Singh et al 2011).…”

“…In the present study, total biomass C stock was estimated as 13 Mg C ha -1 (equivalent to CO 2 sequestered of 47.96 Mg CO 2 ha -1 ), which is much lower than reference forest site. In Indian conditions (19 years old RMS of Singrauli, India), Tripathi et al (2014) reported higher C stock (41.73 Mg C ha -1 ) with an accumulation rate of 2.20 Mg C ha -1 year -1 . Average C accumulation rate in aboveground biomass for reclaimed pine and hardwood forests ranged from 1.4 Mg C ha -1 year -1 in Indiana to 3.3 Mg C ha -1 year -1 in West Virginia (Amichev et al 2008).…”

“…In Indian reclaimed coal mine sites (Jayant project, Singrauli) accumulation of higher C-stock (22.9 Mg C ha -1 ) was reported with an average accumulation rate of 1.20 Mg C ha -1 year -1 (Tripathi et al 2014). C stocks of reclaimed forest and grassland coal mine soils (0-30 cm) of Ohio, USA were reported in higher range of 37-45 Mg C ha -1 and 47-79 Mg C ha -1 over 21 and 25 year periods respectively Lal 2000, 2001).…”

Reclaimed mined lands provide an excellent opportunity to sequester carbon and combat global warming. Carbon sequestration on reclaimed sites depend on age of reclamation, composition of species, geomining conditions (soil characteristics) and prevailing climate. The aims of the present study were to calculate carbon (C)-stock of biomass of 4 years old plantation (dominated by Albizia lebbeck, Dalbergia sissoo and Bambusa arundinacea), understorey vegetation and litter, soil organic carbon in reclaimed minesoil (RMS) and compare with reference forest site. Allometric equation was used for the estimation of biomass C stock and found 13.0 Mg C ha -1 (A lebbeck 7.8 Mg C ha -1 , D sissoo 3.5 Mg C ha -1 and B. arundincea 1.2 Mg C ha -1 ), while stock of understorey vegetation was 0.98 Mg C ha -1 . In RMS, C stock was 16.3 Mg C ha -1 , out of which inorganic C contributed 1.7 g kg -1 (8 % of total soil C), Coal C 8.7 g kg -1(43 % of total soil C) and biogenic C 9.8 g kg -1 (49 % of total soil C). Total C stock in reclaimed site was calculated as 30.3 Mg C ha -1 (equivalent to 111 Mg CO 2 ha -1 ). The study concluded that (i) coal C is responsible for overestimation of C stock in RMS (ii) Maximun C stock stored in aboveground biomass component and (iii) reclaimed mined lands will take approximately 17 years to reach the level of C stock of reference forest site in dry tropical climate.
