Research ArticleOpen accessIn the keywordsEffect of Logging Operation on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Since heavy machinery are used in the logging operation activity for extracting the logs on sensitive forest site with peat soil, environment destruction should be the other concern during its processes especially on its important function as soil carbon storage. The objective of this study was to determine whether logging operation affect soil carbon storage of a tropical … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 8,032 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEffect of Tropical Peat Swamp Forest Clearing on Soil Carbon StorageAhmad Shukri Mat Nuri, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidAbstract: Problem Statement: Forest clearing in Tropical Peat Swamp Forest (TPSF) will affect forest soil carbon storage. Thus this study is essential to determine whether the effect of clearing of forest does to the nature of soil forest concentrating on soil carbon storage. The objectives of this study were to analyze carbon storage values in logged and clear cut TPSF … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,939 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsElectroosmotic Phenomena in Organic SoilsAfshin Asadi, Bujang B.K. Huat, M. M. Hassim et al.Organic soils or peat represent an accumulation of disintegrated plant remains which have been preserved under condition of incomplete aeration and high water content. In order to develop a fundamental understanding of electroosmotic phenomena in peat, initially microelectrophoresis studies were carried out to conceptualize the electrokinetic phenomena. Then electroosmosis experiments were conducted on rigid cube samples containing 0.0001 M NaCl-water … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,101 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsExperimental Investigation on Geomechanical Properties of Tropical Organic Soils and PeatBujang B.K. Huat, Afshin Asadi, Sina KazemianProblem statement: Organic soils and peat were believed to be geotechnically problematic due to their very high compressibility, very low shear strength and difficult accessibility. Although conventional soil mechanics theory could be applied to the soils, it was found that important anomalies existed which required special considerations. Correlations between geomechanical parameters for the soils were known to be important for … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 10,172 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Converting Secondary Forest on Tropical Peat Soil to Oil Palm Plantation on Carbon StorageCh’ng Huck Ywih, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Peat has been identified as one of the major groups of soils found in Malaysia. Sarawak as the largest state in Malaysia has the biggest reserve of peat-land. There are about 1.5 million ha of peat-land in Sarawak, which are relatively under developed. As is the case with any plant, oil palm trees do sequester carbon as they … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 2 · 30 Jun 2009 · 9,039 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOrganic Matter, Carbon and Humic Acids in Rehabilitated and Secondary Forest SoilsLee Yit Leng, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem Statement: Tropical rainforests cover about 19.37 million ha (60%) of Malaysia’s total area and about 8.71 million ha can be found in Sarawak, Malaysia. Excessive logging, mining and shifting cultivation contribute to deforestation in Sarawak. The objectives of this study were to: (i) Quantify soil Organic Matter (SOM), Soil Organic Carbon (SOC) and Humic Acids (HA) in rehabilitated and … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,761 accessesView PDF Cite
