Abstract: A field experiment was undertaken in the six farmer’s fields of Purna valley with soybean crop during Kharif, 2015-16 in randomized block design, replicated six times, with four treatments comprised of only BBF, BBF + FYM @ 5 t ha-1, BBF + gypsum @ 2.5 t ha-1 and BBF + FYM @ 2.5 t ha-1 + gypsum @ 1.25 t ha-1 combined. The use of farm yard manuare and gypsum in broad bed furrow system recorded improvement in physical and chemical and biological properties as well as carbon pools resulting into enhancement in soil parameters. The use of gypsum showed relatively more improvement in exchangeable cations except sodium. The use of organic manure was found beneficial as that of gypsum in physical properties of soils in addition to gradual chemical amelioration. Although considerable improvement in chemical properties has been found under the application of FYM. The FYM was also found useful and superior to gypsum in improving the carbon pools of soil. When gypsum was applied along with FYM, its role in enhancement of organic carbon was noticeable. Similarly application of farm yard manure has shown significant improvement in carbon status of soil. The highest Oxidizable carbon was recorded under BBF with gypsum treatment T4 (131.83 mg kg-1) at 0-15 depth of soil as well as (116.40 mg kg-1) 15-30 cm depth of soil. The highest water soluble carbon was also recorded under combined use of FYM, gypsum and BBF treatment T4 (33.02 mg kg-1) at 0-15 depth of soil as well as (30.68 mg kg-1) 15-30 cm depth of soil. Based on the results, it has been observed that application of farm yard manure @ 5 t ha -1+ Gypsum @ 1.25 t ha-1followed by FYM @ 2.5 t ha-1 has given remarkable results in respect of all carbon fractions. The highest soybean yield (14.03 q ha-1) was obtained with the combined application of gypsum + FYM on BBF. Similarly considerable amount of yield was noticed in other treatments.
