| Abstract | A chemical method based on batch desorption of adsorbed humus on clay-humus complex by sodium hydroxide-sodium pyrophosphate solution was used to assess the stability of humus C through the desorption rate constant using simple first order exponential equation in a toposequence of Western Himalaya region of India. The rate constant values were significantly (p < 0.0001) higher in hill top (0.305 day⁻¹) and narrow valley (0.184 day⁻¹) than side slope (0.125 day⁻¹) and broad valley (0.11 day⁻¹) suggesting higher stability of soil C in side slope and broad valley. This variation implies that clay particles are active in binding humus C and soil texture plays an important role in stabilizing soil C. |
