Information on soil properties derived from different landform and parent material can be used to establish an agricultural development strategy. This study aimed to determine the properties of the soil in Kundur Island. The soil survey was conducted to determine soils distribution and properties. A total of 24 samples from 8 pedons representing each landform and parent material were taken for laboratory analysis. The results showed that soils in Kundur Island were lying in granite intrusion, alluvial, peat, fluviomarine, and marine landform. The soil classifications were Dystrudepts, Hapludults, Udipsamments, Haplohemists, Haplosaprist, and Endoaquepts. The peatland soil was acidic to very acidic (pH 2.6-3.5) with very high Al saturation (62-81%) due to mineral enrichment. Udipsamments derived from granite intrusion have higher carbon content and slightly lower base saturation than Dystrudepts and Hapludults, which were derived from the same parent material. The soil in fluviomarine landform contains very high exchangeable Na (12.9-18.0 cmol c kg −1 ) due to the influence of saline water. For the agricultural development in Kundur Island, soil derived from granite intrusion and peatland need liming to suppress soil acidity while soil derived from clay and sand deposits in alluvial and fluviomarine landform should consider saline water intrusion.
