Mineralogical and Chemical Properties of Some Acid Sulfate Soils in Malaysia and Their Effects on the Growth Performance of Oil Palm Seedlings (Elaeis Ruineensis, Jacq)

Mineralogical and Chemical Properties of Some Acid Sulfate Soils in Malaysia and Their Effects on the Growth Performance of Oil Palm Seedlings (Elaeis Ruineensis, Jacq)

Acid sulfate soils are charllcterized by a very low pH and a high aluminium concentration resulting from the chemical and biological oxidation of pyrite upon drainage. These soils have low agricultural potential due to high acidity and poor physical conditions, which adversely affect crop growth...
