Effect of Different Sulphur Sources on Sulphur Fractionation in a Red Sandy Loam Soil

Aim: The aim of the present study was to examine different forms sulphur fractions in post- harvest soil cabbage crop determine S status red sandy loam soil, Thondamuthur block, Coimbatore district.
 Study Design: design used Factorial randomized block with 20 treatments replicated thrice.
 Place and Duration Study: A field experiment carried out a farmer’s non-calcareous deficient which located at Viraliyur village district during February May 2021 rabi season.
 Methodology: as test fertilized NPK along sources viz., elemental sulphur, potassium sulphate, gypsum single super phosphate @ levels 0, 20, 40, 60 80 kg ha-1 thrice Randomized Block Design. water-soluble S, inorganic organic available residual were estimated post-harvest soil.
 Results: results revealed that total differed from 278.1 339.4 mg kg-1. Among fractions, (39%) accounts highest proportion followed by (38.3%), (9.19%) (4.12%). order was, Inorganic > sulphate water soluble S.
 Conclusion: This indicated all are strongly associated sources, properties under cultivation.
