Research ArticleOpen accessIn the abstractKinetics of Thin Layer Drying of Poultry ManureA. E. Ghaly, K. N. MacDonaldThe poultry industry is one of the largest and fastest growing sectors of livestock production in the world. The estimated 2010 world flock was over 18 billion birds with a yearly manure output of 22 million tonnes. Storage and disposal of raw poultry manure has become an environmental problem because of the associated air, water and soil pollution. Environmental and … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 9,021 accessesView PDFCite
Research ArticleOpen accessIn the abstractSensor Technologies for Precision Soil Nutrient Management and MonitoringA. Bah, S. K. Balasundram, M. H.A. HusniProblem statement: Growing concerns about the need to increase crop productivity without causing environmental injury have led to the deployment of site-specific strategies in soil nutrient management, where nutrients are applied in variable rates to fit local requirements. Variable rate application of nutrients is typically based on a rigorous sampling regime and time-consuming data analyses. The ability to monitor soil … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 25 Jan 2012 · 9,131 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrobial 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 · 7,548 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Field Study of the Fates of Arsenal and Escort Applied on the Cumberland Plateau in TennesseeJohn Harwood, Rong JiangProblem statement: The low organic soils of the Cumberland Plateau, as well as the karst geology of the region, may promote increased transport of herbicides outside of application sites. We have studied the fates of imazapyr and metsulfuron-methyl applied to a privately owned tract on the Cumberland Plateau in Tennessee and compared the field results with herbicide fate predicted by … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,438 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiocontrol of Soil Fungi in Tomato with Microencapsulates Containing Bacillus subtilisMarcela Hernàndez-Suàrez, Francisco Daniel Hernàndez-Castillo, Gabriel Gallegos-Morales et al.Problem Statement: An option to reduce pollution by synthetic agro-chemical in root plant disease management is the use of antagonist rhizobacteria belonging to Bacillus genus, because their inhibitory properties, stimulation of plant growth and crop yield increase. Approach: This study was carried out in order to evaluate if Bacillus subtilis strains could play an antagonists role of plant pathogens and … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 8,934 accessesView PDFCite
Research ArticleOpen accessIn the abstractSugar Beet Performance Affected by Uniformity of N FertigationH. Nouri, M. S.M. Amin, S. J. Razavi et al.In common with the majority of crop species, in sugar beet nutrition nitrogen is an important element due to its role in sucrose utilization and plant growth. Application of precision agriculture, in order to apply the right amount of input at the right time in the right area, is appropriate to decrease chemical use and increase plant growth. Problem statement: … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,936 accessesView PDFCite
Research ArticleOpen accessIn the abstractLead and Cadmium Availability and Uptake by Rice Plant in Response to Different Biosolids and Inorganic FertilizersSeyed Majid Mousavi, Mohammad Ali Bahmanyar, Hemmatollah PirdashtiProblem Statement: Contents of heavy metals in soil are very important because soil is the first link in the food chain. Approach: But, pay attention to importance the subject, we performed this project to investigate the lead (Pb) and Cadmium (Cd) availability and uptake by rice plant in response to different biosolids Municipal Solid Waste (MSW), Vermicompost (VC) and inorganic … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Skidding Operations on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: There is still lack of a study that compares the soil carbon storage of kuda-kuda skidding system and excavator skidding system in tropical peat swamp forests. The objective of this study was to determine whether skidding operations affects soil carbon storage of a tropical peat swamp forest. Approach: Soil sampling was conducted on two different plots (0.3 ha … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 7,712 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Mixing Urea with Humic Acid and Acid Sulphate Soil on Ammonia Loss, Exchangeable Ammonium and Available NitrateMohd Taufik Mohd Yusuff, Osumanu Haruna Ahmed, Nik Muhamad Ab MajidProblem statement: Ammonia loss due to rapid hydrolysis of urea in soil following surface application can be substantial. Ammonia loss in agriculture is estimated to be 1 to 60%. This laboratory study compared the effect of three different urea-humic acid-acid sulphate soil mixtures on NH3 loss and soil ammonium and nitrate contents, with loss from surface applied urea without additives … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 8,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of N and K Fertilizers on Nutrient Leaching and Groundwater Quality under Mature Oil Palm in Sabah during the Monsoon PeriodPetronella G. Ah Tung, Mohd Kamil Yusoff, Nik Muhamad Majid et al.Problem statement: The oil palms are mainly grown in the humid tropics with high rainfall. Soluble Nitrogen (N) and Potassium (K) fertilizers are commonly required by the oil palm plantations to maximize palm productivity due to the highly weathered soils with low fertility. Thus, leaching losses of N and K nutrients may be unavoidable and these nutrients may move further … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 10,149 accessesView PDFCite
