Abstract
This study compares soil respiration rates from oil palm replanting and newly planted oil palm areas on peat at the Malaysian Palm Oil Board MPOB Research Station Teluk Intan Perak and Ladang Sungai Mentelong Endau-Rompin Pahang using survey method. The soil respiration rate was 50 higher in the newly developed peat area 2482 160 mg CO‚‚/m/hr compared to the replanted peat area 1098 69 mg CO‚‚/m/hr. The soil moisture content at the replanted peat area was 39 higher compared to the new developed peat area. Soil respiration rate between control natural ground cover and Mucuna bracteata legume cover crop plots at both sites were not significantly different although slightly higher in the Mucuna bracteata 1762 123 mg CO‚‚/m/hr area compared to the control 1539 118 mg CO‚‚/m/hr. Soil respiration rate was affected by soil moisture which influenced soil respiration directly through physiological processes of roots and microorganisms and indirectly via diffusion ofsubstrate and oxygen where it was influenced by drainage and water level. Drier soil had more air space thus enabled aerobic respiration by root.
