Research ArticleOpen accessIn the keywordsEffects of Converting Secondary Forest to Oil Palm Plantation on Peat Soil Carbon and Nitrogen and other Soil Chemical PropertiesMakilan Muniandy, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohd Khanif YusopProblem statement: Peatlands are natural sequesters of carbon and nitrogen. Once they are disturbed the tendency to lose carbon and nitrogen to the environment is very high. This study investigated the effect of converting peat land forest into oil palm plantation on soil chemical properties with particular emphasis on carbon and nitrogen storage. Approach: Soil samples were collected randomly at … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,308 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect 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 · 8,108 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffects 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 · 9,048 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEngineering Properties and Compressibility Behavior of Tropical Peat SoilYouventharan Duraisamy, Bujang B.K. Huat, Azlan A. AzizThis paper presents the engineering properties and compressibility behavior of various types of tropical peat soil collected from several locations in Malaysia. These soils represented fibric, hemic and sapric type of tropical peat with organic content ranging from 70% to 90%. The correlations of the various basic engineering properties of the tropical peat soils have been found to be close … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 8,573 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPotential Air and Groundwater Pollution from Continuous High Land Application of Cheese WheyA.E. Ghaly, D.G. Rushton, N.S. MahmoudExperiments were performed, using eighteen 280 cm deep soil columns with 20 cm inside diameter, to determine the relative amounts of nitrogenous compounds leached and volatilized from soils receiving high application rates of cheese whey during two seasons. Three soils (loamy sand, sandy loam and sandy clay loam) and two cheese whey application rates (560 and 840 kg-N ha-1), that … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,279 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA 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 · 7,634 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPotential 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 · 8,158 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOntology Based Knowledge Management System Design for Organic FarmingMuqeem Ahmed, Afrah Fathima, Mohammad Islam et al.In the current agricultural system, information is often gathered manually, and farmers make decisions based on their judgment. Occasionally, they seek advice from experts and extension officers. Numerous information systems have recently emerged, offering insights into organic farming practices. However, this information is dispersed across various contexts, formats, and media on the Internet, making it challenging to access. Utilizing ontology … …Journal of Computer Science, Vol. 22, Issue 3 · 25 Mar 2026 · 1,443 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLand Degradation and Preventive Measures From the Perspective of the StakeholdersMosayeb Heshmati, Arifin Abdu, Nik Muhamad Majid, J. ShamshuddinLand degradation at the catchment scale in Iran is widespread, usually assumed to be accelerated by the activities of local inhabitants. Social issues such as low income, poverty and low level of welfare and education contribute to land degradation. A study was conducted to identify the causes of land degradation in Merek catchment, Iran and to propose appropriate measures to … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 8,370 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSoil Formation by Ecological Factors: Critical ReviewSaeed Zeraat Kar, Aydin BerenjianRegolith is the term we give parent material that has been weathered. The regolith consists of weathered bedrock near the surface including the soil layer. In the Iranian soil layer we will find: decayed parent materials, decaying plant material, decaying animal matter (manure) along with vegetation. Results of the present study show us that methods stimulating natural fertility in Iran … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 2 Apr 2013 · 7,666 accessesView PDFCite
