Abstract

The aim of this study was to increase cation exchange capacity and base cations and to alleviate Al toxicity of a highly weathered soil (oxisol) using finely ground basalt rocks. The experiment was carried out using a fine clayey, kaolinitic, isohyperthermic, Rhodic Hapludox (Segamat Series), which was sampled from Jengka, Pahang, Malaysia. It is highlighted that basalt application decreased the point of zero charge (PZC) and the point of zero net charge (PZNC). Cations released from basalt were revealed by the significant increases in Ca, Mg, K and Na both in the forms of exchangeable cations (measured from the solid phase) and soluble cations (measured from the soil solution), with concomitant reduction in Al and Mn contents. Hence, finely ground basalt is a promising natural material that can be used to restore negative charge and base cations and suppress Al and Mn contents of highly weathered soils, which in turn, have a great impact on preventing cation leaching, increasing soil nutrient availability and reducing elemental toxicities
