Potentiometric Titration of Acid Soils From Peninsular Malaysia
The study indicates the dominance of Al in controlling the acidity of acid Peninsular Malaysian soils. The buffering action of the soils is dominated by Al below pH 5.5 and by the clay minerals, mainly kaolinite, at pH above pH 5.5. The rate of extraction of Al from the soils depends on the concen...

| Summary: | The study indicates the dominance of Al in controlling the acidity of acid Peninsular Malaysian
soils. The buffering action of the soils is dominated by Al below pH 5.5 and by the clay minerals, mainly
kaolinite, at pH above pH 5.5. The rate of extraction of Al from the soils depends on the concentration
of the extracting solution. Lime requirement of the soils can be obtained by multiplying the base needed
to raise the pH of the soil to 5.5 by a factor 1.3. |
