Research ArticleOpen accessIn the abstractControlling Ammonia Volatilization by Mixing Urea with Humic Acid, Fulvic Acid, Triple Superphosphate and Muriate of PotashShamsuddin Rosliza, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Inefficient use of inorganic fertilizer such as urea is caused by substantial losses of ammonia when urea is surface-applied. Ammonia losses can be controlled by adding acidic material such as TSP, HA or FA. In order to reduce ammonia loss and retain soil exchangeable ammonium and available nitrate as well as producing complete organic based fertilizer, this study … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 9,540 accessesView PDFCite

Research ArticleOpen accessIn the abstractReducing the Environmental Impact of Olive Mill WastewaterAwni Khatib, Fathi Aqra, Nader Yaghi et al.Problem Statement: A research was needed to monitor the environmental impact of olive mill wastewater (OMW): production and relative production of olive mill waste. This was achieved by collecting data from 92 local olive mills in order to study the olive production yield, water consumption in olive washing and in oil recovery, wastewater generation relative to olive processed and oil … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 8,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractTotal Emissions from Flaring in Kuwait OilfieldsKhaireyah Kh. AL-Hamad, A. R. KhanKuwait is a major oil producing country and its economy directly depends on its export of crude and refined products. Kuwait Oil Company (KOC) is responsible for all exploration and production of crude oil in Kuwait. These activities result in the emission of gaseous pollutants to the atmosphere, particularly from the flaring of undesirable product and excess gases. For environmental … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 8,947 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordUtilization of Banana, Pineapple and Watermelon Wastes-Substrate: As Consortiums to Remediating Cyanide Polluted SoilFlorence Obiageli Nduka, Samuel Chibuike Ubani, Victor Eshu Okpashi et al.The act of processing cassava for varied food products has come with unguided and wide-spread contamination of cyanide in the environment. The need for effective reduction in cost to enable remediation of cyanide-contaminated sites from cassava mill factories is the purpose of this investigation. This involves bio-stimulation of organic wastes with indigenous microorganisms to degrade cyanide. The application of organic … …American Journal of Environmental Sciences, Vol. 14, Issue 2 · 30 Apr 2018 · 9,930 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordUtilization of Sewage Sludge in Agricultural Soil as Fertilizer in the Republic of Benin (West Africa): What are the Risks of Heavy Metals Contamination and Spreading?Fidèle Suanon, Lyde A.S. Tomètin, Biaou Dimon et al.Biosolids are the treated organic residuals, also known as sewage sludge, which are generated from domestic wastewater treatment plants. It is an organic matter and nutrients [phosphorous (P) and nitrogen (N)]-rich material. Due to these properties, it is has been reported to be a suitable fertilizer or soil amendment which can valuably replace synthesized NPK. Unfortunately, this matter is heavily … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 6 Jan 2016 · 14,496 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBioremediation of Petroleum Hydrocarbon-Polluted Mangrove Swamps Using Nutrient Formula Produced From Water Hyacint (Eicchornia crassipes)Frank Anayo Orji, Abiye Anthony Ibiene, Phillip O. OkerentugbaLaboratory-scale studies were carried out using a nutrient formula produced from Eicchornia crassipes plant to achieve bioremediation of crude oil impacted mangrove soil. In a 70 day study, the culturable heterotrophic bacterial population of the Eichhornia crassipes recipe increased from 6.26×105 Cfu/g to 2.69×107 Cfu/g. The control set-up had its total culturable bacterial count increased from 5.76×105 Cfu/g to 1.24×106 … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,643 accessesView PDFCite
