ABSTRACT
An investigation was undertaken to compare the carbon stock under different land use system of Goregaon tehsil in Gondia district, Maharashtra. Soil samples were collected from forest as native soils and paddy cultivated soils more than 10, 50 and 100 years of cultivation. The result indicates that the soils under both the systems were acidic in nature. However, forest soils were richer in organic carbon concentration (0.87 %) than the paddy growing soils (0.32 to 0.54 %). The soils of forest (Control) were found to hold the highest SOC stock of 15.86 tons/ha. The SOC stock in the recently converted forest to paddy were 8.60 tons/ha. The SOC stocks of 50 and 100 years old paddy growing soils varied narrowly and ranged from 11.63 to 11.57 tons/ha. The estimates of SOC stocks clearly indicate that recent (more than 10 years) conversion of forestland into agriculture (namely paddy) resulted in huge loss of SOC in the surface soil to a depth of 30 cm. The results conclusively indicate that the soils those are recently brought under plough (paddy) lost their SOC the most. Therefore, these soils need to be prioritized for carbon sequestration followed by the soils under paddy for over 50 years and 100 years. The SIC pools were very low and showed considerable variation both spatially and vertically which attributed to the acidic nature of the soils.
