Similarly, ecosystem N pool increased at a mean rate of 145 kg ha − 1 yr − 1 (with a range of 77 to 183 kg ha − 1 yr − 1 ) in forest and 45 kg ha −1 yr −1 (with a range of 2 to 82 kg ha −1 yr −1 ) in pasture (Fig.…”

“…Mine land or overburden spoil being deficient in carbon offers potential for large storage of organic carbon. Stahl et al (2003) estimated that carbon accumulations on mine soils were greater than in native sites in Wyoming, USA. Burger and Zipper (2002) also found that forest planted on mine land could be more productive than native forest before mining.…”

Carbon emission is supposed to be the strongest factor for global warming. Removing atmospheric carbon and storing it in the terrestrial biosphere is one of the cost-effective options, to compensate greenhouse gas emission. Millions of acres of abandoned mine land throughout the world, if restored and converted into vegetative land, would solve two major problems of global warming and generation of degraded wasteland. In this study, a manganese spoil dump at Gumgaon, Nagpur in India was reclaimed, using an integrated biotechnological approach (IBA). The physicochemical and microbiological status of the mine land improved after reclamation. Soil organic carbon (SOC) pool increased from 0.104% to 0.69% after 20 years of reclamation in 0-15 cm spoil depth. Soil organic carbon level of reclaimed site was also compared with a native forestland and agricultural land. Forest soil showed highest SOC level of 1.11% followed by reclaimed land and agriculture land of 0.70% and 0.40%, respectively. Soil profile studies of all three sites showed that SOC pool decreased from 0-15, 15-30, and 30-45 cm depths. Although reclaimed land showed less carbon than forestland, it showed better SOC accumulation rate. Reclamation of mine lands by using IBA is an effective method for mitigating CO2 emissions.

“…The moderate disturbance of soil caused by agricultural tillage has resulted in significant losses of SOC in cultivated soils throughout the world. Loss of SOC or SOM has been commonly reported for soils disturbed by activities associated with surface mining (Visser et al, 1984;Harris et al, 1993;Stahl et al, 2002) Reclamation of disturbed and degraded soils generally leads to redevelopment of SOM in the form of plant, microbial and animal residues (Stahl et al, 2003), which greatly contributes to improvement of soil fertility as well as soil structure, water holding capacity, biotic activity, and plant growth (Harris et al, 1996;Lal et al, 1998). Reestablishment of soil carbon pools in disturbed soil also sequesters carbon from the atmosphere where it is contributing to global climate change.…”

Abstract. Soils play a crucial role in the global carbon cycle; they represent a carbon reservoir larger than the atmosphere, they are the site of a number of key carbon transformations (e.g. mineralization and humification), and contain a number of unique carbon pools (e.g. plant litter, humic substances, dissolved organic matter, etc.). Land disturbance associated with surface coal mining results in complete disruption of the soil system, loss of a significant portion of soil carbon content, and disturbance of many of the organisms that play critical roles in the carbon cycle (primary producers and decomposers). One of the challenges of surface mine reclamation is reconstruction of a soil system which functions properly in the impacted ecosystem. The objective of this paper is to report our research findings on the recovery of soil carbon pools in reclaimed surface mined lands. Data from our studies indicate 2 mechanisms are important in the rapid accumulation of C from plant litter into soil: physical protection by soil aggregates and biochemical protection of high lignin content. Examination of chronosequences of reclaimed soils indicates plant litter is rapidly incorporated into soil aggregate structure in most of these soils. Lignin content of reclaimed soils we analyzed were higher than that of nearby undisturbed soils, indicating the recalcitrant nature of soil C in reclaimed soils and/or possibly the slow recovery of lignin degrading organisms, primarily fungi.Assays of potentially mineralizable C indicate concentrations of labile C in reclaimed soils reach amounts similar to those in undisturbed soil within 5 or 6 years after revegetation.
