Potentiometric Titration of Acid Soils From Peninsular Malaysia [PDF]

open access: yes, 1983
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.
