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 keywordsReducing Ammonia Loss from Urea by Mixing with Humic and Fulvic Acids Isolated from CoalAmeera Abdul Reeza, Osumanu Haruna Ahmed, Nik Muhamad Nik Ab. Majid, Mohamadu Boyie JallohProblem statement: Ammonia volatilization is a major pathway for nitrogen loss from surface applied urea. While all top-dressed ammonia and ammonium based N fertilizers can volatilize, the potential loss is greatest with urea and fluids containing urea. As much as 20-50% of N applied to soils is lost through volatilization alone. Thus, the objective of this laboratory study was to … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 10,897 accessesView PDFCite
Research ArticleOpen accessIn the keywordsReduction 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 accessIn the keywordsWastewater Treatment Using Horizontal Subsurface Flow Constructed WetlandS. Sarafraz, Thamer Ahamad Mohammad, Megat J. Megat M. Noor, A. LiaghatThe last few decades witnessed sharp focus on environment pollution and its impact on life in nature. Wetlands can be used for biological treatment of wastewater. Problem statement: Scarcity of water is considered as a global problem and Iran is one the countries which is facing water shortage problem. Pollution of water bodies restrict the availability of water for various … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 8,788 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSpatial Variability of Soil Inorganic N in a Mature Oil Palm Plantation in Sabah, MalaysiaAbdul Rahim Anuar, Kah Joh Goh, Tee Bee Heoh, Osumanu Haruna AhmedThe identification and understanding of soil factors influencing yield variability of oil palm enable their efficient management. Soil samples were therefore collected from a fertilizer response trial on oil palm to study the spatial inorganic N distribution and some selected soil chemical properties as affected by long-term N fertilizer applications. The experiment was conducted on mature oil palms grown on … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,686 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Differentiated Nitrogen Fertilization using Satellite Navigation Systems on the Spring Wheat (Triticum aestivum L.) Crop Yield in the Conditions of Chernozem-Like Soils in the Northern Forest Steppe of the Tyumen Region of RussiaAltynay Oxukbayeva, Nikolai Abramov, Marden Baidalin, Sergei SemizorovSoil cultivation without layers turnover impeded the process of nitrate nitrogen accumulation compared with plowing. The traditional scheme of mineral fertilization applying the averaged standard did not create a heterogeneous level of nutrient supply in primary soil cultivation systems. These factors set them in unequal conditions by default in terms of nitrogen supply to crops. Solid mineral fertilization with the … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 16 Jan 2023 · 5,201 accessesView PDFCite
Research ArticleOpen accessIn the abstractSwiftlet Bacteriophages Concerning Diversity and Biological Features in South Kalimantan, IndonesiaSiti Gusti Ningrum, Hana Cipka Pramuda Wardhani, Intan Permatasari HermawanWe aimed to isolate and characterize bacteriophages infecting Nitrobacter spp. from swiftlet house environments and to evaluate their biological properties as potential biocontrol agents to mitigate nitrate accumulation in edible bird’s nest (EBN) production. Environmental samples were collected from multiple swiftlet houses in South Kalimantan, Indonesia. Samples were enriched with Nitrobacter cultures, and bacteriophages were detected using spot assays followed … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 1 · 17 Apr 2026 · 1,759 accessesView PDFCite
Research ArticleOpen accessIn the abstractCalcium-sorbitol Chelating Technology and Application in PotatoesPengchao Li, Cunzhen Geng, Lingyu Li et al.Researches on low-molecular organic compounds are concentrated in amino acid and Humic acid chelating fertilizer, but few in sorbitol chelated calcium. In this study, selecting sorbitol as chelating agent, the technological conditions of chelating sorbitol with calcium and the effect of sorbitol chelated calcium on potato were studied. The impact factors on the stability of the fertilizer were investigated, including … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 9 Mar 2020 · 9,087 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment and Implementation of Effective Schemes for the Use of Mineral Fertilizers in the Forest-Steppe Zone of the North Kazakhstan RegionZh. A. Nokusheva, E. Ye. Kantarbayeva, M. B. Ormanbetov et al.Nitrogen fertilizers in liquid form have become the most common ones in recent years. Since North Kazakhstan is located in a zone of risky farming, liquid fertilizers are a very productive solution. The purpose of the study was to develop and evaluate the implementation of effective schemes for the use of mineral fertilizers in the forest-steppe zone of the North … …OnLine Journal of Biological Sciences, Vol. 23, Issue 3 · 5 Jun 2023 · 5,297 accessesView PDFCite
