The contribution of nutrients from parent material in three deeply weathered soils of Peninsular Malaysia

Three deeply weathered soil profiles developed over basalt, granite and schist were studied. The isovolumetric calculation was carried out to determine the intensity of elements depleted during weathering. The rain and stream waters near the respective areas were sampled and analysed. Despite the di...
