Abstract:

A study was undertaken during 2017-18 to identify the distribution of forms of carbon and carbon stock in different land management units (LMUs) of Kanginhal sub-watershed in Gadag district of Karnataka. Horizon-wise soil samples were collected from each LMU and analyzed for organic carbon, water soluble carbon, active carbon, inorganic carbon and total carbon. Organic carbon, water soluble carbon and active carbon were decreased with depth in all the LMUs, whereas inorganic and total carbon did not follow any definite trend. Water soluble carbon and active carbon exhibited significant positive relationship with organic carbon, whereas inorganic and total carbon exhibited significant and positive relationship with CaCO3. Organic, water soluble and active carbon were significantly and positively correlated with each other, whereas inorganic and total carbon was significantly and positively correlated with each other. Highest organic carbon stock was recorded in LMU-5, whereas highest inorganic and total carbon stocks were recorded in LMU-6. Inorganic carbon stock contribution was more to the total carbon stock compared to organic carbon stock.
