The prospect of farming in Damar Wulan Village has considerable potential if managed properly. Food crop groups and plantations such as rubber and oil palm are the most dominant commodities cultivated by village farmers. Horticultural plant groups, especially melon crops, are still very limited to be cultivated in this region. Therefore, the prospect of melon cultivation has a great opportunity…
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 gr…
Sulphate soils contain layers of pyrite (FeS2) and if pyrite is oxidized it can lower soil pH. Pyrite oxidized soil has a characteristic rust or reddish yellow color. The pyrite oxidation rate can be reduced by adding ameliorants and controlling the water level. Under flooded conditions, pyrite poses no risk. This study aims to study the effect of coal fly ash and various water conditions on th…
