The field experiment was conducted the year 2014-2015 on the old long-term fertilizer experiment started since 1983 to assess characterization of humus in soil and it’s relation with physical and physic-chemical properties of soil under the long – term effect of integrated nutrient management in sorghum wheat cropping system. The study showed that there was fraction of humus tended to decrease with depth and use of organics like subabul and FYM in conjunction with NPK fertilizers exerted a remarkable impact on the distribution and built up of humus fractions in soil. CaCO3 and EC content in soil did not showed significant correlation with OC, total carbon Humin, Humic acid and Fulvic acid. Further, porosity and WHC showed positive and significant correlation with OC and total carbon. The bulk density and pH showed negative and significant relation with organic carbon and total carbon. Further bulk density and water holding capacity showed positive and significant correlation with Humin and Humic acid, respectively. The pH showed positive and significant relation with Humic acid and Fulvic acid. The porosity showed negative and significant correlation with Humin and Fulvic acid and positive and significant relation with Humic acid.
