Nutrient index of available S in soils of two districts, namely, Howrah and South Dinajpur of West Bengal falling in the soil order Inceptisols collecting 237 soil samples from Howrah and 256 soil samples from South Dinajpur district. Soil samples were collected according to grid sampling pattern maintaining approximately 4.0 km grid for Howrah and 3.7 km grid for South Dinajpur district using global positioning system (GARMIN GPS Version etrex) covering 13 blocks of Howrah and 8 blocks of South Dinajpur district. Soil pH of the Howrah and South Dinajpur district ranged from 3.0to 8.30 with a mean value of 5.75 and 3.7 to 7.0 with a mean value of 5.21.The organic carbon content in soils of Howrah and South Dinajpur district ranged from 0.18 to 1.21% with a mean value of 0.55% and 0.37 to 1.32% with a mean value of 0.84%. Available S content in soils of Howrah and South Dinajpur district ranged from 1.09 to 78.70 mg kg-1 with a mean value of 18.12 mg kg-1 and2.03 to 43.39 mg kg-1 with a mean value of 10.52 mg kg-1.Nutrient index value (NIV) of available soil S of these two districts was 1.38 and 1.10. Results revealed that available soil S status of Howrah and South Dinajpur is medium and low.
