Characterisation, Classification and Suitability for Oil Palm of Some Common Soils in Tawau-Semporna Area, Sabah

Seven most common soils on different parent materials from oil palm estates in Tawau-Semporna area, Sabah were selected for this study. The study was carried out due to the lack of detailed information for proper classification and management of the soils. The objectives are therefore to determin...
