It is the second largest oilseed crop in India after groundnut. Among all agricultural crops soybean is most important crop for carbon sequestration because soybean forms mutualistic symbiosis with mycorrhizal fungi. Mycorrizal fungi contributes in carbon sequestration as it has high constriction of fungal hyphae, the hyphal entanglement stabilizes soil aggregates which may stabilize organic matter against rapid decomposition. The hyphae of arbuscular mycorrhizal fungi produce the glycoprotein, glomalin which may combine with tannin like compound to form a very resistant form of organic matter, a slowly decomposing material. Soybean builds up soil fertility by fixing a large amount of atmospheric nitrogen through its root nodules and also through leaf fall on the ground at maturity. It can be used as fodder, forage and can be made into hay, silage etc. Its forage and cake possess excellent nutritive value for livestock and poultry.

The experiment was laid out in Randomized Block Design with nine treatments replicated three times. The treatments comprised of unfertilized control, chemical fertilizers alone and their combinations with organics viz., FYM and phosphocompost. The soil of experimental site was black belongs to Vertisols. The soil and plant samples were collected and analyzed for their different properties. The application of RDF based on soil test through FYM + remaining P through phosphocompost (100% N through FYM + P compensation through phosphocompost to previous crop) recorded significantly highest soil microbial biomass carbon (SMBC) (232.36 mg kg -1 ) and microbial biomass nitrogen (30.92 mg kg -1 ) (T 7 ). The maximum (2776.73 kg ha -1 ) total biomass was noticed in treatment (T 2 ) where RDF based on soil test (25% N through dhaincha lopping + RDF compensation to previous crop).
