Research ArticleOpen accessEvery word in the titleEffect of Precipitation Fluctuation 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 compare the effect of extremely different rainfall conditions on soil carbon storage of lowland tropical peat swamp forest. Therefore, under these natural rainfall gradient, the objectives of this study were to determine whether rainfall affects soil carbon storage of a tropical peat swamp forest and to determine what correlations between variables occurs which stimulate … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 8,603 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleExperimental 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

Review ArticleOpen accessEvery word in the titleSoil Hydraulic Conductivity and Soil Water Retention of Inland Peat on Various Land Covers (Case Study: Natural Peat and Burnt Peat)Fengky Florante Adji et al.This research aims to examine differences in the rate of saturated soil hydraulic conductivity (permeability) and unsaturated soil hydraulic conductivity (infiltration) and soil water retention with various pressures in peatland with different land covers. The study was conducted from June to October 2021. The research was conducted at the LAHG-Sebangau and at the KHDTK-Tumbang Nusa, central Kalimantan, Indonesia. Based on … …OnLine Journal of Biological Sciences, Vol. 23, Issue 3 · 19 May 2023 · 6,124 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSequential Remediation Processes for Effective Removal of Oil from Contaminated SoilsDeepika Dave, Reema Alharathi, Abdel GhalyProblem statement: Over 2.2 billions of oil and oil products were transported every year and often these activities can result in air, water and soil contamination. Expousure to petroleum products can cause health problems to humn and animals and affect marine animals and wildlife habitats. Approach: The objective of this study was to developed a technology for the remediation of … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 18 Nov 2011 · 8,183 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsMicrobial Activities as Affected by Peat Dryness and AmeliorantEdi Husen, Fahmuddin AgusProblem statement: Acceleration of microbial activities and thus of CO2 emission in drained peat soils used for agriculture, is of the main environmental concern. The objectives of this study were to (i) examine microbial activities in peat samples treated with different levels of water contents and ameliorants and (ii) evaluate the relative contribution of microbial groups to peat respiration. Approach: … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 29 Sep 2011 · 7,546 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsMethods of Utilizing Tropical Peat Land for Housing SchemeYouventharan Duraisamy, Bujang B.K. Huat, Azlan A. AzizThis paper discusses some of the methods and recent technologies in utilizing cheap marginal land such as tropical peat for housing scheme. Buildings on peat are usually suspended on piles, but ground around it may still settle. Therefore a suitable method of construction should be tackle to overcome serious problem such as localized sinking and slip failure, massive primary and … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,669 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCompressibility Behavior of Tropical Peat Reinforced with Cement ColumnsYouventharan Duraisamy, Bujang B.K. Huat, Azlan A. AzizThis paper presents the compressibility of tropical peat reinforced with cylindrical cement columns. When a cement column is installed vertically in peat, its compressibility is reduced because of the hardened skeleton matrix formed by cement particles bonding with adjacent soil particles in the presence of pore water. The effects of the cement column diameter on the compressibility have been investigated … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 7,434 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGIS Mapping of Basal Stem Rot Disease in Relation to Soil Series Among Oil Palm SmallholdersK. Parthiban, R. Vanitah, K. Jusoff et al.Basal Stem Rot (BSR) is a disease caused by fungus which affect oil palm tree. This study aims to visualize the geographical distribution of BSR incidence among oil palm smallholders in Selangor using Geographical Information System (GIS) and its relationship to the type of soil series. The geographical distribution of BSR incidence of smallholders in Selangor were mapped using 168 … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 1 · 5 Jan 2016 · 8,683 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMANGANESE SPECIATION IN SELECTED AGRICULTURAL SOILS OF PENINSULAR MALAYSIAJ. Habibah, J. Khairiah, B.S. Ismail, M.D. KadderiManganese speciation in selected agricultural soils of Peninsular Malaysia is discussed in this study. Manganese concentration in the Easily Leacheable and Ion Exchangeable (ELFE), Acid Reducible (AR), Organic Oxidizable (OO) and Resistant (RR) fractions of soils developed on weathered rocks, soils of mixed nature, alluvium and peat deposits are described.

Research ArticleOpen accessIn the abstractSoybean Response to 1-Aminocyclopropane-1-Carboxylate Deaminase-Producing Pseudomonas under Field Soil ConditionsEdi Husen, Aris Tri Wahyudi, Antonius Suwanto, GiyantoProblem Statement: 1-Aminocyclopropane-1-Carboxylate (ACC) deaminase-producing bacteria have been known to promote plant growth by decreasing ethylene inhibition of various plant processes. However, their efficacy under field soil conditions may vary depending on the range and variability of the environmental factors. This study examined the ability of eight promising isolates of ACC deaminase-producing Pseudomonas to enhance soybean growth under acidic and … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 24 Jun 2011 · 8,250 accessesView PDF Cite
