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...

| description | 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.
Successful reclamation and management of acid sulfate soils
would require an in-depth understanding of the soil's chemical
and mineralogical properties.
In this study, acid sulfate soils at Pulau Lumut, Kelang
were mapped, characterized morphologically and chemically,and classified. Soil solutions were extracted on samples from soil pit,limed and oxidized soils and a pot experiment at the matrix suction of 10 kPa and the activities of the major cations and anions were calculated by Geochem. XRD and TGA were
carried out to deter mine the mineralogy of the various soil
horizons. The morphological features of the minerals in the
soils were studied by TEM and SEM. A controlled pot experiment
was conducted to assess the performance of oil palm seedlings
grown on acid sulfate soils under freely drained and
waterlogged conditions. |
