Abstract

Peat soils of Binsuluk and Klias consists of deep fibrous soft loose organic materials. The thickness of the peat layer widely varies between 1 and 12 m exceeding 3 m at Mawao Lumat and in Klias Forest Reserve. The organic materials still contain the original plant fibers and high amount of carbon nitrogen and phosphorus for as long as these materials remain submerged within the peat swamp environment. The vary low lying peat layer with respect to the average sea level combined with the soft fibrous loose light and very porous nature of the organic materials pose a serious restriction to any physical and agricultural development. There is very little or no humus development derived from the peat materials except for those area where the raised alluvial deposits on Padas river levee have been opened up and drained for over three decades to clear the way for oil palm cultivation in Sabah Land Development Board SLDB scheme Limbawang Membakut and Klias. Underlying the peat materials is the existence of the sand deposit becoming clearly visible as sand bar towards the cost of Binsuluk Kimanis Bay in the north. The underlying sand gradually becomes loam either towards Padas river levee or towards the foot-slopes of the hills and ridges in the east and south. when the peat is drained for agricultural crop cultivation the top layer of organic materials quickly oxidizes disintegrates and eventually disapears causing rapid subsidence. The inherent characteristics and properties of the peat soils of Binsuluk and Klias severely limit agricultural crop cultivation.
