Research ArticleOpen accessIn the abstractCadmium Exposure Via Food Crops: A Case Study of Intensive Farming AreaRaagheni Munisamy, Sharifah Norkhadijah Syed Ismail, Sarva Mangala PraveenaCadmium (Cd) is ubiquitous in environment and may enter food chain through intense application of phosphate fertilizers to agricultural crops. A cross-sectional study was conducted at Kuala Terla and Blue Valley farming villages, Cameron Highlands to determine cadmium concentration in vegetables and soil and to determine the health risks among respondents. A total of 87 respondents were selected based on … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 8,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhosphorus Biogeochemical Cycling in a Sugar Cane AgroecosystemD. Sequera, D. Lopez-HernandezThe annual harvest of sugarcane plantations together with the burning of the crop before harvest, a common practice of management of sugarcane plantations in South America, leads to the loss of significant amounts of nutrients in those agroecosystems. Thus prescribed burning operations could progressively diminish the level of soil organic matter and increase nutrient deficiency in soils of sugar cane … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 29 Jan 2013 · 7,544 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment and Evaluation of Tractors and Tillage Implements Instrumentation SystemS. A. Al-Suhaibani, A. A. Al-Janobi, Y. N. Al-MajhadiProblem statement: Field machines contribute a major portion of the total cost of crop production. Proper selection and matching of farm machinery is essential in order to reduce the cost of crop production. Performance data for tractors and implements are, therefore, essential for farm machinery operators and manufacturers alike. The aim of this study was to develop and evaluate an … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,304 accessesView PDFCite
Research ArticleOpen accessIn the abstractLong-term Effect of Conventional and No-Tillage Production Systems on Nitrous Oxide Fluxes from Corn (Zea mays L.) Field in Southwestern QuebecAbdirashid Elmi, Bano Mehdi, Chandra Madramootoo et al.Problem statement: There is a growing trend in the adoption of conservation tillage as an alternative to conventional tillage farming system. Implications of this agricultural management shift with respect to nitrous oxide (N2O) emission, which has been a topic of intense research for the past few decades, is not yet completely understood. Approach: This study was conducted on a 2.4 … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,016 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroundwater Nitrate Contamination Risk Assessment: A Comparison of Parametric Systems and Simulation ModellingDario Sacco, Marco Offi, Marina De Maio, Carlo GrignaniGroundwater nitrate contamination is a source of rising concern that has been faced through the introduction of several regulations in different countries. However the methodologies used in the definition of Nitrate Vulnerable Zones are not included in the regulations. The aim of this work was to compare different methodologies, used to asses groundwater nitrate contamination risks, based on parametric systems … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,122 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordUtilization of Sewage Sludge in Agricultural Soil as Fertilizer in the Republic of Benin (West Africa): What are the Risks of Heavy Metals Contamination and Spreading?Fidèle Suanon, Lyde A.S. Tomètin, Biaou Dimon et al.Biosolids are the treated organic residuals, also known as sewage sludge, which are generated from domestic wastewater treatment plants. It is an organic matter and nutrients [phosphorous (P) and nitrogen (N)]-rich material. Due to these properties, it is has been reported to be a suitable fertilizer or soil amendment which can valuably replace synthesized NPK. Unfortunately, this matter is heavily … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 6 Jan 2016 · 14,496 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAssessment of Heavy Metals Uptake and Translocation by Aquilaria malaccensis Planted in Soils Containing Sewage SludgeKeeren Sundara Rajoo, Arifin Abdu, Hazandy Abdul-Hamid et al.Increase in human population has resulted in an enormous growth in the volume of wastewater. The conventional methods of sewage sludge disposal, that is the by-product of wastewater treatment, are costly and not environment-friendly. An ideal way for sewage sludge management is by using it as a soil amendment in agricultural land due to sewage sludge’s high organic matter content. … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,079 accessesView PDFCite
