Acid sulphate soils contain sulfidic materials (pyrite). Changes from anaerobic to aerobic conditions will cause pyrite oxidation, releasing sulfuric acid, resulting in oxidation of iron, and lowering soil pH. This study aimed to investigate the effect of dolomite application and soil water conditions on the inhibition of pyrite oxidation in acid sulfate soil. This study was conducted in the greenhouse of the Department of Soil, Faculty of Agriculture, Universitas Sriwijaya testing two treatments, namely dolomite application (D0 = Without dolomite and D1 = dolomite application at 18.75 g per kg of soil) and water condition (K1= Kept submerged to a depth of 5 cm and K2= submerged up to 5 cm and allowed to dry). The results showed that the application of dolomite affected soil pH significantly but it did not exert a significant effect on the dissolved Fe sulfate Keeping soil submerged showed significant effects on all parameters in current study. However the interaction between dolomite application and keeping the soil submerged to a depth of 5 cm did not significantly reduce Fe and sulfate solubility. Keywords: dolomite, oxidation of pyrite and water conditions.
