An investigation was undertaken to evaluate suitable extractant for available sulphur, different forms of sulphur (S) and their relationship with soil properties in paddy Soils of Saharanpur district (U P). Total, organic sulphur, sodium dihydrogen phosphate extractable sulphur, heat soluble sulphur and calcium chloride extractable sulphur ranged between 261 to 670,114 to 435.8, 14.7 to 50.7, 14.0 to 48.5 and 47.7 mg kg−1, respectively, with corresponding average values of 434.4, 250.2, 30.5, 28.3 and 26.3 mg kg−1. Sulphur forms in the soil of study area were found above the critical limit for paddy crop. Forms of sulphur had significant positive correlation with OC, available N and clay, but not with pH, EC, CaCO3, K, silt and clay.
