Research ArticleOpen accessIn the abstractField Scale Modeling to Estimate Phosphorus and Sediment Load Reductions Using a Newly Developed Graphical User Interface for Soil and Water Assessment ToolAaron R. Mittelstet, Erin R. Daly, Daniel E. Storm et al.Streams throughout the North Canadian River watershed in northwest Oklahoma, USA have elevated levels of nutrients and sediment. Soil and Water Assessment Tool (SWAT) was used to identify areas that likely contributed disproportionate amounts of Phosphorus (P) and sediment to Lake Overholser, the receiving reservoir at the watershed outlet. These sites were then targeted by the Oklahoma Conservation Commission (OCC) … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 28 Dec 2012 · 6,470 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRemediation of Diesel Contaminated Soils Using Surfactants: Coulumn StudyE. Salehian, A. Khodadadi, B. HosseiniThis study presents the experimental remediation studies of diesel contaminated soil with Sodium Deducible Sulfate (SDS) as surfactants using column tests. Sandy selected soil had the grain size distribution of # 40 meshes to the # 200 mesh range. The soil columns were contaminated with adequate diesel amount to achieve the concentration of 10000 and 20000 ppm in soil. 0.1, … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 8,320 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Polypropylene Fibers on the California Bearing Ratio of Air Cured Stabilized Tropical Peat SoilBehzad Kalantari, Bujang B.K. Huat, Arun PrasadProblem statement: Peat soil is well known to deform and fail under a light surcharge load and is characterized with low shear strength, high compressibility and high water content. With the rising demand from the construction industry, utilization of these soils is required and suitable technique needs to be found out for stabilizing them. Approach: Model study had been carried … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,697 accessesView PDF Cite

Research ArticleOpen accessIn the abstractControlling Ammonia Volatilization by Mixing Urea with Humic Acid, Fulvic Acid, Triple Superphosphate and Muriate of PotashShamsuddin Rosliza, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Inefficient use of inorganic fertilizer such as urea is caused by substantial losses of ammonia when urea is surface-applied. Ammonia losses can be controlled by adding acidic material such as TSP, HA or FA. In order to reduce ammonia loss and retain soil exchangeable ammonium and available nitrate as well as producing complete organic based fertilizer, this study … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 9,540 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEngineering of Ground for Liquefaction Mitigation Using Granular Columnar Inclusions: Recent DevelopmentsA. Murali Krishna, M.R. MadhavProblem statement: Liquefaction was the most hazardous damage during an earthquake. Ground improvement techniques were employed to mitigate liquefaction hazards. Most common methods to improve engineering properties of soils are densification, reinforcement, grouting/mixing and drainage. Among various remedial measures available, installation of columnar granular inclusions is the most widely adopted method for liquefaction mitigation. Approach: Columnar granular inclusions function as … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 7,736 accessesView PDF Cite

Research ArticleOpen accessIn the abstractReduction of Ammonia Volatilization through Mixing Urea with Humic and Fulvic Acids isolated from Palm Oil Mill Effluent SludgeShamsuddin Rosliza, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Ammonia volatilization from surface-applied urea may be substantial but it is possible to control it by mixing urea with acidic substances such as Humic Acids (HA) and Fulvic Acids (FA). The objective of this study was to compare the effects of urea-HA, urea-FA, urea-acidified (HA+FA) mixtures on ammonia loss, soil pH, soil exchangeable ammonium and available nitrate accumulation … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,350 accessesView PDF Cite

InvestigationOpen accessIn the abstractThe Influence of Biorganic Fertilizers on Productivity and Quality of Vegetables in the System of "Green" Vegetable Farming in the Conditions of the South-East of KazakhstanTemirzhan Erkasovich Aitbayev, Zharas Zholdybaevich Mamyrbekov, Akbope Temirzhanovna Aitbayeva et al.The purpose of the research was to study an influence of biofertilizers and new types of biological products for the yield and quality of vegetables in the South-East of Kazakhstan. In Kazakhstan, organic farming began to develop after the adoption of the Act "On Organic farming" in 2015. The development of "green" technologies is very important for the production of … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 29 Jan 2018 · 7,941 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPotential Plant Species for Live Pole Application in Tropical EnvironmentSasan Mafian, Bujang B.K. Huat, Nordin A. Rahman, Harwant SinghProblem statement: Slope instability causing landslides, a major geologic hazard, is a risk common to most regions. Among all categories of landslides, shallow slope failures which affect many hill slopes and earthwork projects are the most wide spread and pose the most costly maintenance problem. One of the soil improvement methods that seem suitable for preventing shallow slope failures is … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 7,594 accessesView PDF Cite
