Research ArticleOpen accessPhrase in the titleOrganic 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 PDFCite
Research ArticleOpen accessPhrase in the titleA Comparative Assessment of the Characteristics of Saturated Wetland Soil and a Well Drained Forest SoilA. Snow, A. E. GhalyA surface flow wetland was constructed in the Burnside Industrial Park, Dartmouth, Nova Scotia, to treat stormwater runoff from the surrounding watersheds which are comprised primarily of commercial properties and two former landfills. The aim was to protect a freshwater ecosystem that consists of a 4.6 km long brook and two lakes. A comparative analysis of the pH, total and … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 7,630 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProposed Soil Quality Index for Rehabilitated Tropical Forest Sites in MalaysiaDaljit Singh Karam, Arifin Abdu, Keeren Sundara Rajoo et al.A proposed soil quality index named Tropical Soil Quality Index 2 (TSQI2) was developed in this study using statistical analysed data of selected properties (physical, chemical and biological) of composite soil samples collected from natural, secondary and rehabilitated forests of Chikus and Tapah Hill Forest Reserves, Perak, Malaysia. Results of soil evaluation using TSQI2 showed higher values for planted forest … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 30 Dec 2016 · 8,154 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessing Soil Biological Properties of Natural and Planted Forests in the Malaysian Tropical Lowland Dipterocarp ForestDaljit Singh Karam, Arifin Abdu, O. Radziah et al.Problem statement: A study was conducted to evaluate and compare the soil biological properties of a natural forest and an 18-year-old stand of Shorea leprosula in Chikus Forest Reserve, Perak, Malaysia. Approach: Soils were sampled at depths of 0-15 cm (topsoil) and 15-30 cm (subsoil) in six subplots (20×20 m) of natural forest (C1) and of a planted S. leprosula … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 29 Jul 2011 · 7,961 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect 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 PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Converting Secondary Tropical Peat Swamp Forest into Oil Palm Plantation on Selected Peat Soil Physical PropertiesMohd Suffian Firdaus, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: The conversion of forest land into oil palm plantation is considered to be one of the causes of soil degradation and loss of tropical land forest in Southeast Asia. The objective of this study was to compare selected peat soil physical properties of secondary tropical peat swamp forest and oil palm plantation to determine the effect of forest … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,742 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect 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 PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Skidding Operations on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: There is still lack of a study that compares the soil carbon storage of kuda-kuda skidding system and excavator skidding system in tropical peat swamp forests. The objective of this study was to determine whether skidding operations affects soil carbon storage of a tropical peat swamp forest. Approach: Soil sampling was conducted on two different plots (0.3 ha … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 7,709 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Chemical Properties on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to investigate the seriousness of degradation of peat swamp forest caused by skidding system in terms of its function as a carbon sink. In this study, we formulated assumptions that conditions of our research site before the introduction of skidding system were in their natural states, thus that changes measured are clearly caused by skidding … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,915 accessesView PDFCite
