A study was carried out to determine the effect of drainage and land clearing on selected peat soil
physical properties of secondary peat swamp forest. This study was conducted in a drained secondary
peat swamp forest and a cleared site of drained secondary peat swamp forest at Sibu, Sarawak,
Malaysia. A 300 m2 experimental plot was prepared at both sites. Saturated hydraulic conductivity,
bearing capacity and surface soil temperature were determined in-situ, while fiber content, soil bulk
density, gravimetric water content, volumetric water content, loss on ignition, ash content and soil total
porosity were determined using standard laboratory procedures. Unpaired t-test was used to compare
the variables for the two sites using statistical analysis system software. The percentage of fibre
content, volumetric water content and saturated hydraulic conductivity were not significantly different
between the two sites. Gravimetric water content, loss on ignition and total porosity were significantly
higher in the drained secondary peat swamp forest, while ash content, bulk density, surface soil
temperature and bearing capacity were significantly higher in the cleared site of drained secondary peat
swamp forest. After clearing the drained secondary peat swamp forest, gravimetric water content, loss
on ignition and total porosity continuously decreased while surface soil temperature increased as well
as ash content, bulk density and soil bearing capacity. The changes of peat soil physical properties in
the drained secondary peat swamp forest after the land clearing are the important indicators that
indicate some continuous processes of peat soil degradation after the draining. However, fiber content,
volumetric water content and saturated hydraulic conductivity of the drained secondary peat swamp
forest were not affected by the land clearing.
