Abstract

The knowledge of different sulphur (S) forms and their relationship with soil properties is of much relevance in assessing the short- and long-term availability of the nutrients to crops and in formulating sound fertilizer recommendations. For this purpose one hundred and one representative soil samples were collected from the study area and analyzed for various physicochemical properties and forms of sulphur (water soluble, exchangeable, available, organic, non-sulphate and total S) using standard methods. The different forms of sulphur viz., water soluble, exchangeable, available, organic, non-sulphate and total sulphur ranged from 1.1 to 7.0, 1.9 to 10.9, 3.1 to 21.1, 75.9 to 316.1, 8.0 to 41.5 and 75.5 to 372.5 mg kg-1, respectively in soils of Outer Himalayas under different land uses. The content of different forms of sulphur present in these soils were in the order of total sulphur, organic sulphur, non-sulphate sulphur, available sulphur, exchangeable sulphur and water soluble sulphur. All the forms of S correlated positively and significantly with organic carbon and clay content of soils. A negative and significant relationship was also observed between all forms of sulphur and sand content of soils. In the present study, it was also found that all forms of S present in soils were significantly and positively correlated with each other. The knowledge regarding different forms of S in soils and their availability controlled by different soil properties will be helpful for its management to optimize crop yields in the Outer Himalayas of Himachal Pradesh.
