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. |
