As an essential indicator of soil quality, soil organic carbon (SOC) and its fractions play an important role in many soil chemical, physical, and biological properties. The study was conducted during 2013-14 at research farm of Dr. P.D.K.V. Akola to find out the effect of integrated nutrient management on organic carbon fractions and vertical distribution of carbon under soybean-chickpea cropping sequence of a typic Haplustept of Vidarbha region of Maharashtra. Effect of varying doses of NPK, NPK + FYM, NPK + cotton stalk and NPK + phosphocompost on carbon fractions such as organic carbon, microbial biomass carbon, potassium oxidizable carbon, CO2 evolution and organic carbon stock was studied at 4th cycle of soybean-chickpea cropping sequence. Results revealed that application of FYM, phosphocompost and cotton stalk significantly increased the organic carbon, microbial biomass carbon, and KMnO4¬ oxidizable carbon and CO2 evolution over sole use of chemical fertilizers and control. However, maximum amount of soil organic carbon, microbial biomass carbon, KMnO4¬oxidizable carbon and CO2 evolution was found in 100% NPK + 5 t FYM ha-1 treatment as compared to sole use of chemical fertilizers. Integrated use of FYM with chemical fertilizers or use of FYM alone exerted significant effect on soil organic carbon fraction.
