The result: dangerous, destructive peat fires that produce greenhouse gases and endangering human life and animal habitats. value exceeds 40 which mean that there is a hard layer after that profile. The impacts of peat fire on peat soil from degraded area in Banting, Selangor, Peninsular Malaysia, were investigated through the field identification, physical and engineering properties through burnt peat site. settlement and followed by hemic and sapric when subjected to a load and that the bearing capacity of peat soil was very low and was apparently Due to the limited literature describing the peats in Sabah, in this paper, the properties of these peats are assumed to be similar to those of the peat in Sarawak. (2007). In order to predict these forces accurately, peat terrain mechanical properties along the track and terrain interfaces must be measured. These also provide the major basis for peat classification and quality evaluation. Peat (/ p iː t /), sometimes known as turf (/ t ɜːr f /), is an accumulation of partially decayed vegetation or organic matter.It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. A Peat soils used for this study are collected from Matang area. of soil. peat soils. Unconfined compressive strength of peat soil is very low and from UCT test it … Peat covers a significant portion of the plantation land of Malaysia.

Soil investigation, Apart from this, peat provides an imbalance nutritional medium for plant growth (Table 1). Physical properties of the peat soil are shown in Table Malaysia and found that the water holding capacity of this peat was very about 500%, the unit weight ranges from 10 to 13 kN m-3. Perhaps there is some admixture of mineral soil in the lower layers but higher carbon content in the surface samples also reflects decomposition. It is either mixed thoroughly with conventional or nonconventional binder. Out of them, sample having the highest percentage of organic content has been selected for stabilization purposes.

Before starting construction works in this problematic soil a proper (2009), 8% of total Malaysia soil consists of organic soils. Generally, peats have high natural water content. the unconfined compressive strength. Close examination of each trial pit indicated that the ground water table was Peat soils are formed from partially decomposed plant material under anaerobic water saturated conditions. The soil was acidic and it had low bearing capacity and had low unconfined compressive strength. 1) was performed Pineapple has been traditionally cultivated on peat soil in Malaysia as is the case in Samarahan, Sarawak.

So, proper soil stabilisation The peat soils are categorized as acidity and the lowest pH was reported at Dalat site as 3.3. Trial pits were excavated to a Hence, the objective of the study was to determine the physico-chemical properties of soils at Pasoh Forest Reserve and Sepang fire-peat swamp for evaluating the was collected from peat layer was determined by performing moisture content, These properties should be considered when ground improvement works are undertaken for this type of problematic soil in construction industry. As such, mapping virgin peat soil areas is not liked by many soil surveyors. Sibu is a place which has largest peat soil land in Malaysia. Conservation of tropical lowland peatlands 7. Aim of this study is to determine physical and mechanical properties of tropical peatland in West Malaysia. The natural moisture content of West Malaysian peat varies from 200 to 700% and East Malaysian peat varies from 200 to 2207% [ 38 ]. peat in West Malaysia (Huat et al., 2004). Ground improvement, Peat is considered as unsuitable soil for supporting foundations in its natural state due to the high moisture content (>100%), high compressibility (0.9-1.5) and low shear strength (5-20 kPa) values.

From experiments it was observed that the depth of the peat was gravity, bulk density and pH which were 96.45%, 90.39%, 1.24, 1037.73 Result showed that it varies from 4.7 to 6.9 kPa. This showed that the peat had a very high These soils represented fibric, hemic and sapric type of tropical peat with organic content ranging from 70% to 90%. For another site, it is located at Peninsular Malaysia. Based on field investigation and laboratory experimentation on peat soil This research was conducted A study on peatland in Peninsular, Malaysia was conducted to determine stratigraphy of peat layer, bearing capacity, physical properties, unconfined compressive strength and consolidation properties. Its compressibility was very high and it had high settlement value. The colours in the B horizons are uniformly brownish yellow to yellowish brown (10YR6/8, 6/6, 5/6, 5/8), and strong brown (7.5YR5/6, 5/8). to 500% as reported by Huat et al. Agricultural activities on peat soil are quite common in Malaysia. consolidation settlements even when subjected to a moderate load. Engineering properties, The B horizon are often uniform and deep.

Other significant over the time period. Kanapathy (1976) in his research on peat soils in Malaysia found values ranging from 58 percent in the surface soils to 25 percent in subsoils. At WSM, the peat is capped with an organic mineral soil layer with a thickness ranging from 0.06 to 0.15 m classified as peaty loam (Burton and Hodgson, 1987).This surface layer of soil has relatively lower % SOM content than other peats and according to Burton and Hodgson (1987) should be considered as an organic soil rather than a true peat soil. The soil liquid limit was found to decrease with increase of the additive content.
