Research ArticleOpen accessIn the abstractMicrobial Response to the Application of Amendments in a Contaminated Soil with Trace ElementsA. Branzini, M. S. Zubillaga, M. M. ZubillagaProblem Statement: The anthropogenic activities can cause adverse effects in soils, increasing in some situations trace elements contents, impacting negatively both the microbial biomass and activity. Among the practices used for the recovery of soil quality we can find the application of organic amendments or the product of their composting. These can adsorb trace elements decreasing their availability and increasing … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,180 accessesView PDFCite
Research ArticleOpen accessIn the abstractAccumulation and Movement of Four Potentially Toxic Elements in Soils Throughout Five Years, During and After Biosolid ApplicationMarta Susana Zubillaga, Raúl Silvio LavadoIn this research, we have studied the accumulation of four PTEs (Cadmium, copper, lead and zinc) during and after biosolid application, in two soils with different clay content and their eventual movement with depth. The study was performed in the Province of Buenos Aires, Argentina, on a Typic Argiudoll and on a Typic Hapludoll. Treatments were: control and biosolid application, … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,207 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimple Method of Purifying Humic Acids Isolated from Tropical Hemists (Peat Soil)Susilawati Kasim, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohd Khanif YusopThe objectives of this study were: To investigate whether a purification period of HA isolated from Hemists peat soils could be reduced and to investigate whether distilled water could be used to purify HA isolated from Hemists peat soils. Standard procedures were used to extract and fractionate HA in a Hemists peat soil. The isolated HA was purified by suspending … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Rhizobacterial Inoculation on Growth of the Sweetpotato CultivarY. Farzana, O. RadizahSweetpotato (Ipomoea batatas L.) is the most important of local tuber crops in Malaysia. It is usually planted on marginal soils such as peat and sandy soils. Malaysian consumes a lot of sweetpotato and its production requires high fertilizer input, which can lead to increased production cost and environment problems. The use of bio-fertilizer and bioenhancer such as N2 (nitrogen) … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractCadmium Exposure Via Food Crops: A Case Study of Intensive Farming AreaRaagheni Munisamy, Sharifah Norkhadijah Syed Ismail, Sarva Mangala PraveenaCadmium (Cd) is ubiquitous in environment and may enter food chain through intense application of phosphate fertilizers to agricultural crops. A cross-sectional study was conducted at Kuala Terla and Blue Valley farming villages, Cameron Highlands to determine cadmium concentration in vegetables and soil and to determine the health risks among respondents. A total of 87 respondents were selected based on … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 8,537 accessesView PDFCite
Research ArticleOpen accessIn the abstractTolerance of Accessions of Glagah (Saccharum spontaneum) to Drought Stress and Their Accumulation of ProlineAminatun Munawarti, Taryono, Endang Semiarti et al.Glagah (wild sugarcane, Saccharum spontaneum) is a perennial grass that grows well in marginal soils. It has a high carbohydrate and fibre content, making it suitable for ethanol production and the study industry. Thus, glagah has potential as a crop species in its own right and may also be used in sugarcane breeding programs. However, glagah germplasm has not been … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 4 Feb 2013 · 7,879 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrowth Enhancement and Disease Reduction of Soybean by 1-Aminocyclopropane-1-Carboxylate Deaminase-Producing PseudomonasEdi Husen, Aris Tri Wahyudi, Antonius Suwanto, GiyantoProblem statement: 1-Aminocyclopropane-1-Carboxylate (ACC) deaminase-producing bacteria have been known to ameliorate the inhibition-effect of increase concentration of ethylene in higher plants, which can be triggered by high concentration of indole-3-Acetic Acid (IAA) and/or by the presence of plant pathogens. This study examined the potential use of Pseudomonas isolates producing ACC deaminase as well as IAA to enhance soybean growth and … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 23 Sep 2011 · 7,914 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Tropical Peat Swamp Forest Clearing on Soil Carbon StorageAhmad Shukri Mat Nuri, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidAbstract: Problem Statement: Forest clearing in Tropical Peat Swamp Forest (TPSF) will affect forest soil carbon storage. Thus this study is essential to determine whether the effect of clearing of forest does to the nature of soil forest concentrating on soil carbon storage. The objectives of this study were to analyze carbon storage values in logged and clear cut TPSF … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,941 accessesView PDFCite
