Research ArticleOpen accessEvery word in the titleReduction of Ammonia Loss from Urea through Mixing with Humic Acids Isolated from Peat Soil (Saprists)Regis Bernard, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Application of urea as a source of nitrogen fertilizer has an adverse effect on ammoniacal loss to the environment. This study was conducted to reduce ammonia loss from urea by mixing with Humic Acids (HA) isolated from Saprists peat. Approach: The effects of urea amended with four different amounts of humic acids, 0.25, 0.50, 0.75 and 1.00 g … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,846 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReduction of Ammonia Volatilization through Mixing Urea with Humic and Fulvic Acids isolated from Palm Oil Mill Effluent SludgeShamsuddin Rosliza, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Ammonia volatilization from surface-applied urea may be substantial but it is possible to control it by mixing urea with acidic substances such as Humic Acids (HA) and Fulvic Acids (FA). The objective of this study was to compare the effects of urea-HA, urea-FA, urea-acidified (HA+FA) mixtures on ammonia loss, soil pH, soil exchangeable ammonium and available nitrate accumulation … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,350 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReduction of Ammonia Loss by Mixing Urea with Liquid Humic and Fulvic Acids Isolated from Tropical Peat SoilSusilawati Kasim, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid et al.Problem statement: Fertilizer N use efficiency is reduced by ammonia volatilization. Under low soil CEC and high pH, N from soil solution is released to the atmosphere. Ammonia loss due to low worldwide N use efficiency (33%) has been implicated in global warming. Thus, the objectives of this laboratory study were to evaluate the effectiveness of liquid humic and fulvic … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 9,513 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLarge Eddy Simulation of an Ammonia JetM. Salinas-Vazquez, A. Espinosa, E. Barrios, W. VicenteA compressible jet flow of ammonia was studied through a series of Large Eddy Simulations. Simulations were focused in the zone where the inertial effects are much bigger than the gravitational ones. The ammonia jet is discharged into an air medium and the gases are treated as a two non-reactive ideal gas mixture. Different simulations were performed, going from the … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,740 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimization of Rumen Bioprocess through The Addition of Phosphorus and Sulfur Minerals on Ammoniated Palm Leaves and Fronds (Elaeis Guineensis Jacq.)Suyitman, Lili Warly, James Hellyward, Roni PazlaThis research aims to determine the optimal dosage of Phosphorus (P) and Sulfur (S) minerals for rumen microbial fermentative activity. The research method used an experimental method with a factorial randomized block design (3×3) with three repetitions for mineral P and S. P was the first factor with three dose levels, namely Po = 0.0%, P1 = 0.27% and P2 … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 22 Oct 2021 · 6,352 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleExploring the Potential for Concentration of Nutrients from Urine Using Solar Evaporation and Carbon Dioxide Trapping of AmmoniaTesfamariam Y. Debessai, Ababu T. Tiruneh, Gabriel C. BwembyaNutrients derived from urine such as nitrogen, phosphorous and potassium constitute valuable sources of fertilizers needed for growing plants and as alternatives to commercial fertilizers. Concentration of nutrients available from urine provides advantages of reducing the volume of transportation, the health risk and making nutrient application to soil stable and suitable. An exploratory review of a possible technology for concentration … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 28 Oct 2019 · 7,167 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDissolved Ammonia Adsorption in Water Using Over Burnt BrickShukra Raj Paudel, Bhagwan Ratna KansakarProblem statement: The groundwater of Kathmandu Valley contained very high concentration of ammonia nitrogen which was in excess of WHO guideline value for drinking water. Approach: This study mainly focused on the removal of ammonia nitrogen in water by adsorption in locally available over burnt brick. The study was carried out in a 4.2 cm internal diameter column of 120 … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 8,451 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleInternal Indicators of Digestibility in Diets Containing Ammoniated Hay from Leaves of the Babassu Palm in the Maintenance of GoatsAntonia Leidiana Moreira, Arnaud Azevêdo Alves, Miguel Arcanjo Moreira Filho et al.The efficiency of the indigestible Dry Matter (DMi), indigestible Neutral Detergent Fibre (NDFi), indigestible Acid Detergent Fibre (ADFi) and Indigestible Lignin (LIGi) internal indicators was evaluated as a replacement for the method of total faecal collection in estimating faecal dry matter excretion and Dry Matter (DM) digestibility in diets containing hay from leaves of the babassu palm ammoniated with 4% … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 22 Nov 2021 · 5,950 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCOMBINATION OF CONVENTIONAL AND IN-SILICO APPROACH FOR IDENTIFYING AN INDUSTRIALLY IMPORTANT ISOLATE OF AEROMONASThungri Ghoshal, Sourav Ghosh, Amrita Saha et al.Ammonia is required for various commercial applications while its production by standard process is immensely energy intense. Dairy industry on the other hand produces huge volume of effluent needing treatment before discharge. This study aims at developing an eco-friendly microbial approach for conversion of dairy industry effluent into ammonia under atmospheric pressure and 37°C temperature at laboratory scale. Thus the … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 26 Feb 2014 · 7,921 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluence of Dietary Curcumin on Rumen Fermentation, Macronutrient Digestion and Nitrogen Balance in Beef CattleT. Vorlaphim, M. Phonvisay, J. Khotsakdee et al.Abstract: Problem statement: Previous studies have shown that curcumin has antibacterial activity. It was hypothesized that the feeding of curcumin to ruminants may disturb rumen function and affect macronutrient digestibility and nitrogen utilization. Approach: In an experiment with Latin-square design, beef cattle were fed rations consisting of urea-treated rice straw and concentrates without or with 0.1 or 0.2% added curcumin. … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 26 Jul 2011 · 9,152 accessesView PDFCite
