Abstract: A long-term fertilizer experiment (LTFE) in mulberry [Morus alba L.] variety S1635 has completed 20 crop cycles on a sandy clay loam soil at the Institute farm at Berhampore, West Bengal comprising nutrient-input treatments of varying origin. Soil organic carbon stock (SOCS) under different treatments has been computed by exercising analytical organic carbon content with bulk density (BD) and depth of soil It is creditable to note that SOCS has been improved due to application of organic as well as inorganic combination of nutrients resources and also organic, inorganic as well as biological combination of nutrients resources over sole chemical fertilizers as well as treatment without any nutrient input. Subsequent impact of SOCS on soil fertility and growth as well as yield attributes of mulberry has also been studied and found mostly positive
