Abstract

The case study was conducted in the area of Acacia mangium plantation at BKPH Parung Panjang, KPH Bogor. The objective of the study was to formulate equation models of tree root carbon mass and root to shoot carbon mass ratio of the plantation. It was found that carbon content in the parts of tree biomass (stems, branches, twigs, leaves, and roots) was different, in which the highest and the lowest carbon content was in the main stem of the tree and in the leaves, respectively. The main stem and leaves of tree accounted for 70% of tree biomass. The root-shoot ratio of root biomass to tree biomass above the ground and the root-shoot ratio of root biomass to main stem biomass was 0.1443 and 0.25771, respectively, in which 75% of tree carbon mass was in the main stem and roots of tree. It was also found that the root-shoot ratio of root carbon mass to tree carbon mass above the ground and the root-shoot ratio of root carbon mass to tree main stem carbon mass was 0.1442 and 0.2034, respectively. All allometric equation models of tree root carbon mass of A. mangium have a high goodness-of-fit as indicated by its high adjusted R2.

Abstract

The role of forests as carbon sink and carbon store is undoubtedly important to reduce the carbon amount in the earth atmosphere thereby preventing greenbouse (GHG) effect that can induer the global warming. Among the varisar types of forest, peat swamp forest serves as the largest carbon store. A research bas been carried out at the fiber wond plantation forest comprising mostly Acacia crassicarpa species that grew on a peat land, at the Pelalawan sector, Rian Province. The research was to obtain allometric equatios that related the growth parameters of A. crassicarpa trees (Le tree diameter (D) and height either a total (tot) or branch free (Hbc)) to their growth products Le.biomess (W) and carbon mass (C). It was found that the best fitted and must representative allometric equations were consecutively IF= 0.398918D Hix (for estimating biomass patency) and C = 0.131D Htol""" (for carbon mass potency) Fartbremore, samples A. Crassicarpa tree from different stand ages (2,3,4, and 5 years old) covering particular free portions (Le main stems, branches, twigs, leaves, and roots) were tested for moisture contents, specific growity/density, ash content, volatile matter and fisced carbon. The allometric equations obtained were used to measure and estimate the biomass and carbon mass potencies of A. crassicarpa tree stands at their age group, iz. 2,3,4 and 5 years old Using those allometric equations, the estimates of biomass (W) of A. Crassicarpa for age 2, 3, 4 and 5 years old are 44.98 tons/ha, 70.35 tons/ha, 134.05 tons/ba, and 234.78 tons/year. The potency of carbon mass are 12.09 tons/ha, 36.23 tons/ha, 76.09 tons/ha and 133.10 tons/ha, for stand age 2,3,4 and 5 respectively.
