Abstract |
Soil microorganisms play a central role in decomposition, nutrient mineralization, and
nearly all ecological processes in a soil ecosystem. A number of soil microbiological parameters,
notably microbial biomass carbon and basal respiration, have been suggested as the promising
indicators of soil quality. Therefore, this study aims to investigate microbial respiration as an
indicator of microbial activity under different ages of rubber tree in different season. Three
treatments were selected, categorized by tree age included: rubber trees 4-5 years old, 12 years
old, and 22-23 years old. Soil samples were taken from a randomly selected location in each
plot, at 0-10 cm, in rainy and dry season. The physical and chemical properties of the soil were
also observed. The result showed that soil microbial biomass carbon, activity and MicroResp-
CLPP (community level physiological profile) were influenced by rubber ages and season. The
highest carbon dioxide emission, which was related to microbial activity, was found in the
4-5 years old rubber tree, during the rainy season. However, contrary results emerged during
the dry season. In addition, the more aged rubber trees exhibited a higher microbial biomass
carbon. The results further demonstrated that bacterial biomass and soil activity were higher
than that of the fungi. In rainy season, MicroResp-CLPP showed the highest catabolic responses
in young age (4-5 years old) of rubber tree followed by tapped rubber tree (12 and 22-23 years
old). Contrary, the highest catabolic responses in dry season was observed in tapped rubber
tree (12 and 22-23 years old). These findings suggested that microbial biomass and relative
activity were directly correlated with the rubber tree age. |
