Sulphur (S) dynamics was studied in the present investigation to assess the S status of the cultivated soils of Himachal Pradesh. Eighty soil samples (0-0.15m depth) were collected randomly across different districts of Himachal Pradesh and their S adsorption-desorption behavior was investigated. Results of the study indicated that adsorption of sulphate was more in medium textured soils as compared to coarse textured soils. The sorption capacity of the soils varied widely and followed the order: medium > fine > coarse textured soils. The amounts of sulphate extracted varied considerably among different soils and increased with increase in the amount of S sorbed. Freundlich isotherm represented better fit for fine and medium textured soils while Langmuir isotherm showed better fit for coarse textured soils. S desorption was analyzed using Langmuir desorption isotherm which depicted the higher desorption capacity of coarse textured soils.
