SUMMARY
The present study was carried out in the Sadar Tehsil of Pratapgarh District of Uttar Pradesh to examine the different forms of sulphur (i.e., total sulphur, organic sulphur, NaH2PO4 extractable sulphur, heat soluble sulphur and 0.15% CaCl2 extractable sulphur) in its soil. For this purpose, soil samples at the depth varying between 0 to 120 cm from 10 locations were collected. These locations are Bakulahi (S-1), Benipur (S-2), Chakbantod (S-3), Chaughar Pure anti (S-4), Chaukhad (S-5), Jagdishpur (S-6), Jahanaipur (S-7), Jahargo (S-8), Kaila Kala (S-9) and Khurdaha (S-10). It was observed that the total sulphur content decreases with increasing the soil depth in all the sampling locations. The similar trend was also observed in organic sulphur, Sodium dihydrogen ortho phosphate (NaH2PO4) extractable sulphur, heat solublesulphur and 0.15% CaCl2 extractable sulphur. Correlation coefficient studies showed that total sulphur has significant and positive correlation with pH, EC, OC, CaCO3 and sand while negative correlation with clay and CEC. Organic sulphur correlated significantly and positively with all parameters, except clay and CEC which showed negative correlation with it. The NaH2PO4 extractable sulphur showed significant positive correlation with pH, EC, OC and sand while negative correlation with CaCO3, clay and CEC. Heat soluble sulphur had significant positive correlation with all parameters, except CaCO3 and clay which showed negative correlation with it. The 0.15% CaCl2 extractable sulphur showed positive correlation with pH, EC, OC and sand while negative correlations with CaCO3, clay and CEC.
