Status and distribution of different fonns of sulphur from the surface (0. to 25 cm) sulphur and subsurface (25 to 50 cm) soils of 12 different established soil series of Entisols in West Bengal was studied. Regarding different forms of sulphur, the inorganic sulphate sulphur, organic and total sulphur seemed to vary from 8.4 ppm to 16ppm, 108 to 286 ppm and 120 ppm to 300ppm respectively. A general decreasing trend over the subsurface horizon was found in all the three forms (excepting Bamundanga, Khagrabari and Poshgarh series). The physico chemical properties of these soils showed almost the decreasing trend down the horizon. The inorganic sulphate sulphur, the plant available sulphur was found to be medium to low in sulphur status. Taxonomic analysis of mean values of all the three fonns of sulphur was perlonned for different soil series of Entisols originated under different agroecological conditions of West Bengal.
