    Effect of compaction on soil CO2 and CH4 fluxes from tropical peatland in Sarawak, Malaysia
    (Springer, 2021) Nur Azima Busman; Nagamitsu Maie; Che Fauziah Ishak; Muhammad Firdaus Sulaiman; Lulie Melling
    Tropical peatland stores a large amount of carbon (C) and is an important C sink. In Malaysia, about 25% of the peatland area has been converted to oil palm plantation where drainage, compaction and groundwater table control are prerequisite. To date, relationship between land compaction and C emission from tropical peatland is scarcely studied. To understand the effect of compaction on soil carbon dioxide (CO2) and methane (CH4) flux from tropical peatland, a laboratory soil column incubation was conducted.

    Heavy metals in soils and crops in Southeast Asia
    (Springer, 2004) Bernhard A. Zarcinas; Che Fauziah Ishak; Mike J. McLaughlin; Gill Cozens
    In a reconnaissance soil geochemical and plant survey undertaken to study the heavy metal uptake by major food crops in Malaysia, 241 soils were analysed for cation exchange capacity (CEC), organic carbon (C), pH, electrical conductivity (EC) and available phosphorus (P) using appropriate procedures. These soils were also analysed for arsenic (As), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn) using aqua regia digestion, together with 180 plant samples using nitric acid digestion.
