Abstract
A preliminary study on microclimate and the concentration of carbon dioxide of sago forest mango orchard and oil palm stand was conducted at a portion of the riverbank of Kuala Selangor River located in Kampung Kuntan Kuala Selangor. Each representative site of the habitats was installed with a microclimate station for a period of six months. The microclimate station comprised carbon dioxide light relative humidity RH air and soil temperature sensors. It was placed at 1 m above ground level and under the canopy at each site at about 15-20 m away from the riverbank. Means ofIight intensity CO2 RH air temperature and soil temperature at depths of 5 and 20 cm were analyzed. The results showed that mango orchard was significantly more open than oil palm and sago forest by having the highest mean photosynthetic photon flux density PPFD. High PPFD of the orchard resulting in significant rise of its mean air temperature and soil temperature at 5 cm depth but with a lower mean midday RH than oil palm and sago forest. The finding shows that the concentration of carbon dioxide of sago forest was significantly the highest denoting high decomposition activity followed by the fruit orchard and lastly oil palm stand. Significantly lowest decomposition activity in oil palm may indicate the use of agrochemicals such as insecticide herbicide and fungicide had reduced the population of the decomposers. This paper also discusses the implication of the changes of microclimate on the decomposition rate of the three habitats.
