Abstract
A laboratory experiment was conducted to study soil fertility status of some selected soils of Birbhum district of West Bengal with one hundred soil samples collected from five blocks viz., Mayureswar, Nalhati-1, Bolpur, Md Bazar and Rajnagar. The soils of this zone are characterized by sandy loam to sandy clay loam in texture and strong to moderately acidic in reaction. Total soluble salt content (EC as dSm-1) was found to be under very low level (<1.0) indicating the safe limit for soils, where low to medium organic carbon contents, low to medium in available N, P and K content, while available Sulphur content of all the soil samples was low.
Keywords: Available sulphur, EC, organic carbon, lateritic soil.
