Research ArticleOpen accessEvery word in the titleCharacteristics of Nitrogen Removal from Old Landfill Leachate by Sequencing Batch Biofilm ReactorLong Tengrui, Anas F. Al-Harbawi, Lin Ming Bo et al.Municipal landfill leachate is a high strength wastewater characterized by high concentrations of organics and ammonia and potentially containing toxic materials. The paper reports the results of a laboratory scale investigation aimed at evaluating the effectiveness of mature municipal landfill leachate treatment by a biological stage (used SBBR as a biological treatment) to study the nitrogen removal capabilities for treatment … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 8,039 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEmission of Nitrogen Dioxide from Butane Gas Heaters and Stoves IndoorsMarwan Ghosn, Roula Flouty, Najat A. SalibaLevels of indoor nitrogen dioxide (NO2) in a home equipped with butane gas stove and heaters are reported between the months of February and July 2003. Diffusion passive sampling was used for the simultaneous measurements of indoor and outdoor NO2 concentrations. The overall average indoor NO2 concentrations were 15.6 and 22.3 μg m-3 for the living room and kitchen, respectively, … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 9,471 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTHE IMPACT OF THE POLYMER COATING NUTRISPHERE™ IN INCREASING NITROGEN USE EFFICIENCY AND CORN YIELDTimothy A. Smith, Ronnie W. Heiniger, Pawel WiatrakCurrently, it is estimated that 50 to 60% of the N applied fertilizer is actually utilized by the crop with the remaining N lost through leaching or denitrification. A three year study was conducted at eight locations in North Carolina to examine the impact of Nutrisphere™ on corn yield, optimum N rate, maximum yield, tissue N concentration, plant biomass and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 21 Dec 2013 · 8,037 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSpatial-Temporal Yield Trend of Oil Palm as Influenced by Nitrogen Fertilizer ManagementAbdul Rahim Anuar, Kah Joh Goh, Tee Bee Heoh, Osumanu Haruna AhmedOne of the major challenges in oil palm (Elaeis guineensis Jacq.) plantations today is proper interpretation of yield maps for site-specific management and identification and understanding of the causal factors influencing the variability of oil palm yields. A study was conducted to examine the structural yield variation in order to assess the spatial and temporal yield trends so as to … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,549 accessesView PDFCite
Technical ReportOpen accessEvery word in the titleFish Pond Storage Preserves Chili Puree, but Nitrogen Flow-Through Fails: Unravelling the MechanismDaimon Syukri, Rina Yenrina, Rini et al.Perishable food preservation in rural and resource-limited settings remains a significant challenge, as conventional techniques frequently depend on synthetic additives or energy-intensive processes incompatible with green chemistry principles. This study evaluated fish pond immersion as a novel, low-cost preservation method for freshly ground chili purée, investigating its efficacy with and without continuous nitrogen gas flow. Chili purée samples were packaged … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 30 Mar 2026 · 1,344 accessesView PDFCite

This research intends to study the interaction between Azolla application treatments with different doses of inorganic fertilizers and find out the appropriate dose of Azolla for inorganic fertilizers. This study was conducted in the experimental field … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 9 Feb 2023 · 6,532 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Bradyrhizobium Japonicum on Nitrogen Concentration in Soybean Leaves and Seeds Cultivated on Acidic SoilsBen Tshibuyi Kasu-Bandi, Fabien Kitengie Kitengie, Jonas Lwamuguma Bagaluza et al.The legume-rhizobium symbiosis plays an important role in Nitrogen (N) uptake by plants, more particularly in the humid tropical region where soils are deeply weathered and have poor electrochemical properties. However, the influence of Bradyrhizobium on N allocation in soybean organs is not clearly understood. Here, we assessed the effect of Bradyrhizobium japonicum on the N concentration of soybean leaves … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 24 Jan 2022 · 7,663 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetection of Soil Total Nitrogen, Phosphorus and Potassium Content Based on the Spectral Information of Citrus CanopyLin Yunshuo, Li Zhen, Lv Shilei et al.The content of total nitrogen, phosphorus and potassium in the soil is an important basis for calculating the best fertilization amount and realizing the reasonable fertilization of the orange planting soil in time and accurately. In this research, hyper-spectral technology is applied to detect the three soil nutrient elements in the cultivated soil of citrus trees. Four spectral bands with … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 17 Apr 2020 · 7,805 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Enriching Nitrogen and Phosphorus on the Growth of Sargassum Podacanthum Cultured in Potassium-Fortified Inland Saline WaterHa Thi Thu Bui, Trong Quoc Luu, Ravi FotedarPotassium-fortified inland saline water (K+ISW) has shown potential for growing marine species, including seaweed species. The response of a brown seaweed species, Sargassum podacanthum, to nitrogen and phosphorus enrichments were evaluated by culturing the species for 84 days in K+ISW and comparing it with Ocean Water (OW).
