Research ArticleOpen accessIn the abstractEffect of Different Ages of a Rehabilitated Forest on Selected Physico-chemical PropertiesRajeswari A.P. Murugayah, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: This research was important because of still lack of information about rehabilitated tropical forest age effect on infiltration rate. The objectives of this study were to determine the influence of age of forest on soil water infiltration rate and to evaluate the influence of forest age on the relationship between water infiltration rate, soil organic matter and soil … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,104 accessesView PDFCite
Research ArticleOpen accessIn the abstractAccumulation and Movement of Four Potentially Toxic Elements in Soils Throughout Five Years, During and After Biosolid ApplicationMarta Susana Zubillaga, Raúl Silvio LavadoIn this research, we have studied the accumulation of four PTEs (Cadmium, copper, lead and zinc) during and after biosolid application, in two soils with different clay content and their eventual movement with depth. The study was performed in the Province of Buenos Aires, Argentina, on a Typic Argiudoll and on a Typic Hapludoll. Treatments were: control and biosolid application, … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,206 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial Variability of Soil Inorganic N in a Mature Oil Palm Plantation in Sabah, MalaysiaAbdul Rahim Anuar, Kah Joh Goh, Tee Bee Heoh, Osumanu Haruna AhmedThe identification and understanding of soil factors influencing yield variability of oil palm enable their efficient management. Soil samples were therefore collected from a fertilizer response trial on oil palm to study the spatial inorganic N distribution and some selected soil chemical properties as affected by long-term N fertilizer applications. The experiment was conducted on mature oil palms grown on … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,686 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Boundary Conditions on the Behavior of an Anchored Reinforced Earth WallFaisal Hj Ali, Bujang B.K. Huat, Lee Chee HaiThe finite element model is used to simulate the behavior of the full scale instrumented anchored reinforced wall. The validated finite element model is then used to carry out parametric studies to ascertain the influence of the boundary conditions on the behavior of the wall. The boundaries at the crest, facing and base of the wall are varied to study … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,029 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeo-Seismic Environmental Aspects Affecting Tailings Dams FailuresJuan M. Mayoral, Miguel P. RomoSeismic performance evaluations of tailings dams are essential for characterizing the geo-environmental risks posed by these earthen structures, which should include the geotechnical hazards implied by slope instability failure, free board loss and the potential release of contaminants. The observed damage is more important when liquefaction occurs on the dam body and foundation, which often leads to cracking, settlements, tilting … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,086 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Performance of EPS Footing for Lightweight Farm Structure on Peat SoilMohammad Abdullah, Bujang B.K. Huat, Rezuwan Kamaruddin et al.The objective of this research project was to find a potential replacement for the conventional pile foundation principally for peat soil. It is fundamentally meant for lightweight and impermanent agricultural farm structures. Preceding the design and development of the foundation the physical characteristics of the in-situ peat such as; peat depth, soil consolidation, soil compressibility, water table, liquid limit, soil … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,239 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Fate of Non-Volatile Organic Chemicals in The Agricultural EnvironmentMohammad A. Batiha, Abdul Amir H. Kadhum, Zahedi Fisal et al.Multimedia dynamic model of the fate of non-volatile organic chemicals (NVOC) in the agricultural environment is described. The modeled environment, consisting of up to three major surfaces environmental compartments, includes air, agricultural soil, and surface water. This model is based on the aquivalence approach suggested by Mackay and co-workers in 1989. As the movement of chemicals in the environment is … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Environmental and Health Impacts of High Land Application of Cheese WheyA. E. Ghaly, N.S. Mahmoud, D.G. Rushton, F. ArabA laboratory scale experiment was carried out to study the transformation and transport of nitrogenous compounds in soils receiving high application rates of cheese whey (twice the nitrogen requirement for crops). The experimental apparatus consists of 36 soil columns constructed of 20 cm inside diameter PVC pipes. Three types of soil (sandy loam, loam and sandy clay loam) and three … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 8,155 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordField Behavior of A High Anchored Reinforced Earth WallFaisal Hj Ali, Bujang B.K. Huat, Lee Chee HaiSince the invention of Reinforced Earth by the French architect Hendri Vidal in 1966, numerous reinforced soil walls have been designed and constructed all over the world. In this study the focus was on a particular type of reinforced wall called Nehemiah wall which differed from the Vidal type in the sense that instead of steel strips, the reinforcing elements … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,258 accessesView PDFCite
