Abstract

Soil is the primary store of terrestrial carbon, and is disturbed by mining activities. Carbon sequestration is a unique measure for combating the green house gas emission. Carbon sequestration, and increase in soil organic carbon (SOC) also takes place in disturbed soils, such as those naturally reclaimed mined out areas. This natural reclamation of the dumps and the backfilled areas can lead to the recuperation and sequestration of soil organic carbon (SOC). SOC accumulated in the dumps and soil of backfilled area replenishes the loss of SOC due to mining. In this paper, we have measured SOC contents in some dumps and backfilled areas, approximately zero to twenty years old, in chronosequence, keeping 2009 as base year. In this paper, data obtained by field measurement from various overburden dumps and backfilled areas is analyzed to indicate the rate of replenishment of SOC in dumps of different ages.
