Research ArticleOpen accessEvery word in the titleEffects of Mixed Organic and Inorganic Fertilizers Application on Soil Properties and the Growth of Kenaf (Hibiscus cannabinus L.) Cultivated on Bris SoilsMohd Hadi Akbar Basri, Arifin Abdu, Shamshuddin Jusop et al.The demand for kenaf in the world increases rapidly by the years. Cultivation of the crop in Malaysia is a challenging task, especially when kenaf is grown on sandy soils with low fertility, such as the BRIS Soils (Beach Ridges Interspersed with Swales). A pot study was conducted in a glasshouse at Universiti Putra Malaysia to evaluate the potential of … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 28 Oct 2013 · 8,779 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSugarcane Response to Water-Deficit Stress during Early Growth on Organic and Sand SoilsDuli Zhao, Barry Glaz, Jack C. ComstockProblem statement: Approximately 20% of sugarcane (Saccharum spp.) is grown on sand soils in south Florida, USA. Sugarcane yields in the region linearly increased in last 33 years on organic (muck) soils, but not on sand soils. Water deficit during the formative growth phase on sand soils probably limits sugarcane yields. Approach: A greenhouse study was conducted in 2009 and … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 10,263 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSorption of Phenols: Influence of Groundwater pH and of Soil Organic Carbon ContentSilvia Fiore, Maria Chiara ZanettiProblem statement: Physical and chemical properties of soil, groundwater and pollutants deeply influenced the type and the strength of sorption phenomena involving hydrophobic organic contaminants: Soil fraction of organic carbon (foc) and cation exchange capacity, groundwater pH and pollutants hydrophobicity were with undoubtedly the predominant issues. Approach: In this study an experimental study of the sorption of phenol and 2-nitrophenol … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,010 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Organic Based N Fertilizer on Dry Matter (Zea mays L.), Ammonium and Nitrate Recovery in an Acid Soil of Sarawak, MalaysiaSusilawati Kasim, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid et al.Problem statement: Exchangeable ammonium (NH4+) could be recovered by humic and fulvic acids from humic substances. The ability of these acids in fixing or retaining NH4+ has been demonstrated in many findings and reports. Both acids could affect the plant growth, nutrients uptake by enhancing photosynthesis rate and root growth among others. Thus, in this study, the effect of both … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 8,252 accessesView PDFCite
