Changes in litter, decomposition, nitrogen mineralization and microclimate in Acacia mangium and Acacia auriculiformis plantation in Mount Makiling, Philippines
The objectives of this study were to examine litter, decomposition, net mineralization and microclimate by two leguminous species planted for the restoration of degraded area. The total annual litter fall in A. mangium site was 11.44±0.59 (mean ± standard error) t ha -1 yr -1 and A. auriculiformis site was 8.72±0.57 t ha -1 yr -1 . Decomposition constant (k) of A. mangium and A. auriculiformis ...

متن کاملEcological Impact on Nitrogen and Phosphorus Cycling of a Widespread Fast-growing Leguminous Tropical Forest Plantation Tree Species, Acacia mangium
Symbiotic nitrogen fixation is one of the major pathways of N input to forest ecosystems, enriching N availability, particularly in lowland tropics. Recently there is growing concern regarding the wide areas of fast-growing leguminous plantations that could alter global N2O emissions. Here, we highlight substantially different N and phosphorus utilization and cycling at a plantation of Acacia m...
متن کاملEffect of Hardwoods Characteristics on Kraft Pulping Process: Emphasis on Lignin Structure
In an attempt to explain variations in delignification behaviors among different hardwood species, the kraft pulping delignification rates of Eucalyptus urograndis, E. nitens, E. globulus, sweet gum, maple, red oak, birch, red alder, cottonwood, and acacia were obtained and correlated with their respective lignin chemical structures. Since H-factor for hardwood is calculated based on the softwo...
متن کاملMolecular Characteristics of Kraft-AQ Pulping Lignin Fractionated by Sequential Organic Solvent Extraction
Kraft-AQ pulping lignin was sequentially fractionated by organic solvent extractions and the molecular properties of each fraction were characterized by chemical degradation, GPC, UV, FT-IR, (13)C-NMR and thermal analysis. The average molecular weight and polydispersity of each lignin fraction increased with its hydrogen-bonding capacity (Hildebrand solubility parameter). In addition, the ratio...
