Incorporation and Transformations of Elemental Sulphur in High pH Soils of Malaysia

Mehdi Karimizarchi, Aminuddin Husin, Mohd Khanif Yusop and Radziah Othman    

Abstract: Knowledge of elemental Sulphur (S) oxidation and its effect on soil chemical properties is seamlessly required before it can be recommended for use as a soil amendment or acidulate source. Therefore, a batch experiment was carried out to quantify various S fractions and to study how elemental S amendment affects S dynamics in Bintang series soil. Results showed that elemental S, applied up to 1 g S kg-1 soil, was successfully oxidized and converted to both organic and inorganic forms. While inorganic water soluble S appeared to be the predominant form of S, comprising more than 65% of total S, for Bintang series soil amended with elemental S rate of 0.25 g S kg-1 and more, organic form of S was the major form, comprising more than 96% of total S, in the soil amended with 0.125 g S kg-1 and less. Regarding soil remediation, elemental sulphur will be efficient for enhancing soil micronutrient availability and it can act as a source of some micronutrients for agricultural practices in Bintang Series soil.
