Abstract: Soil Organic Carbon (SOC) is a very crucial element in soil fertility and productivity. It is found in the soil in the forms of labile and non-labile. The labile form contains three fractions that are frac1 (very labile carbon), frac2 (labile carbon) and frac3 (less labile carbon), and frac4 of the carbon is non-labile. The experiment was conducted at the Research cum Instructional Farm, IGKV, Raipur, (C.G.) during Kharif season 2018-19. The soil sample was collected at 0-15 cm and 15-30 cm soil depth. The four carbon fractions i.e. very labile carbon (VLC), labile carbon (LC), less labile carbon (LLC), non-labile carbon (NLC) were compared in randomized block design (RBD) with three replications. The treatments consisted of organic and inorganic combination of T1[Control(N0P0K0), T2 [100% N through Organic Source (1/3 FYM, 1/3 vermicompost, 1/3 Neem cake )], T3 (75% N through Organic Source + 10% foliar spray of Vermiwash and Cow Urine at 25-30 DAS and 50-60 DAS), T4 (50% N through Inorganic + 50% N through Organic), T5 (75% N through Organic + 25% N through Inorganic), T6 (100% N through Inorganic). The carbon fractions were not significantly affected by all the treatments. The higher carbon fractions recorded in 100% N through organic source (1/3 FYM, 1/3 Vermicompost, 1/3 Neem cake) at surface (0-15 cm) and sub-surface (15-30 cm) soil as compared to control (N0P0K0). The yield of soybean significantly different in all the treatments. The maximum seed yield in treatment T3 (75% N RDF through organic source) and stover yield of soybean in T2 (100% N through Organic Source (1/3 FYM, 1/3 vermicompost, 1/3 Neem cake).
