Higher organic carbon content measured by dry combustion method compared to wet oxidation. Between wet oxidation methods Colorimetric method gives higher recovery than WB method. There is high correlation between dry combustion-WB method and dry combustion-Colorimetric method. Organic carbon recovery estimated higher in surface soil of Aridisol. A higher correction factor reported for Alfisol in wet oxidation methods. Subsurface soil has high correction factor than subsurface soil.
