Distribution of forms of carbon and carbon stock in different land management units of Kanginhal Sub-watershed in northern dry zone of Karnataka, India

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. | Distribution of forms of carbon and carbon stock in different land management units of Kanginhal Sub-watershed in northern dry zone of Karnataka India
