Abstract:

A study on forms and distribution of carbon in the soils of Dambal sub-watershed of Mundargi taluk of Gadag district, Karnataka was undertaken during 2018-19. One representative soil profile for each soil series was selected to represent twenty two soil series identified under Sujala-III project. Depth wise soil samples were collected and analysed for forms of carbon. Soils were generally sandy clay loam to clay in texture, bulk density and particle density increased with depth and on contrary porosity was decreased with depth. The pH and EC values ranged from neutral to strongly alkaline and normal to strongly saline respectively. Organic carbon content followed decreasing trend with depth and irregular distribution was observed in free CaCO3. CEC of soil series was average with Ca2+ found as dominant exchangeable cation followed by Mg2+, Na+ and K+. Majority of soils possessed medium to high per cent base saturation. Organic, water soluble and active carbon fractions were decreased with depth in all the soil series, whereas inorganic and total carbon did not follow a particular trend. Water soluble and active carbon showed significant positive correlation with organic carbon, whereas inorganic and total carbon showed significant and positive correlation 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.
