Available in PDF, EPUB and Kindle. Book excerpt: The low solubility of many rock phosphate (RP) around the world is the main cause of their ineffectiveness when applied to soil as a source of P for crops. The low solubility decreases their value as P fertilizers and prevents their widespread use, especially for high P demanding crops. One method proposed to enhance RP solubility is to add sulfur (S) as an amendment. The oxidation of S to H2SO4 in the soil results in dissolution of the applied RP. This study tested three Brazilian RP sources (Araxa, Catalao, and Patos de Minas) mixed with S at a ratio of 5:1 (RP:S). The application of the RP-S mixtures proved to be a promising alternative method for increasing RP solubility and thus their effectiveness as P sources. The soil pH decreased proportionally to increasing rates of RP-S application. The NaHCO3 extractable soil P increased as a consequence of increased soil acidefication. The ryegrass growth, P uptake, plant P concentration and P recovered from RP sources were enhanced only when S was mixed with the RPs. On the other hand, when RP sources were applied directly without S, the available soil P as measured by NaHCO3 extraction was depleted with time regardless of source or rate of RP. The inefficiency of the directly applied RP sources to supply adequate P was evidenced by less plant growth than applied with S. Also, in addition to this inadequate supply of for plant assimilation, the directly applied RP sources failed to develop a residual reserve of available P in the soil, even at very high application ...

This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Working Group M.O. (Interactions of soil minerals with organic components and microorganisms) (WGMO) of the International Soil Science Society (ISSS) was founded in 1990 at the 14th World Congress of Soil Science (Kyoto, Japan), with Professor P.M. Huang being the Chairman. Since then, the Working Group M.O. has served as a forum to bring together soil chemists, soil mineralogists, soil microbiologists, soil biochemists, soil physi cists and environmental, ecological, and health scientists. The objective of the Working Group M.O. is to promote research, teaching, and also the exchange of technology concerning the knowledge and the impact of the interactions between minerals-organics and microorganisms on environmental quality, agricultural sustainability, and ecosystem "health". This group is first a scientific group as defined just previously, but it also intends to develop exchange and transfer between scientists and engineers. The first International Meeting organized by Professor P. M. Huang, was held in Edmonton, Canada, in August 1992, where 87 papers were presented by scientists from 20 countries. Following this meeting, a two volume book was edited by P. M. Huang, J. Berthelin, J.-M. Bollag, W. B. McGill, and A. L. Page, entitled "Environmental impact of soil component interaction" : Volume I "Natural and anthropogenic organic-volume II "Metals, other inorganic and microbial activities", and published by c.R.C. Lewis Pub lishers (1995).

Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, SIld disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna and broader dissemination. tional publishing house to assure improved service Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 30 (thesis year 1985) a total of 12,400 theses titles from 26 Canadian and 186 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work.

Download or read book Beneficial Microbes for Sustainable Agriculture under Stress Conditions written by Tongmin Sa and published by Elsevier. This book was released on 2024-03-19 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beneficial Microbes for Sustainable Agriculture under Abiotic Stress: Funtional Traits and Regulation highlights the potential for microbe-mediated stress phytolerance to be improved by presenting multiple scenarios of application and results. In most research and studies, abiotic stress is applied singularly to specific plants inoculated with a bioinoculum or a bacterial consortium to isolate specific plant-microbe responses. However, in reality, plants are continually exposed to a multitude of different stresses simultaneously occurring. This book presents bacteria functional traits and bacteria-mediated plant responses under both specific or combined stress conditions. Collectively, it provides insights into bacterial functional traits and bacteria-mediated plant responses in a wide range of conditions, providing foundational understanding of their potential benefits, and inspiring further research. The book centers on specific bacterial strains and groups which have been shown to effectively promote stress tolerance, and which could be utilized to boost agricultural production under stress conditions. Their potential utilization in stress affected lands not just improves crop production but could also be in line with sustainable agriculture. With the advancement of tools such as Omics related technologies, emerging information on bacterial functional traits and regulations on bacteria mediated phytotolerance will also allow us to develop relevant biotechnologies harnessing potentials of plant-bacteria interactions under stress conditions. The information in this volume will be of interest to those working toward these next steps. Includes microbial functional traits and responses common to all stresses, unique to specific stress and shared by multiple stresses Focuses on microbial strains and groups proven to be most effective in promoting stress tolerance Explores opportunities toward improvement of sustainable agriculture and resulting food security
