Book Synopsis Biological Nitrogen Fixation by : Frans J. de Bruijn
Download or read book Biological Nitrogen Fixation written by Frans J. de Bruijn and published by John Wiley & Sons. This book was released on 2015-06-16 with total page 2250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is arguably the most important nutrient required by plants. However, the availability of nitrogen is limited in many soils and although the earth's atmosphere consists of 78.1% nitrogen gas (N2) plants are unable to use this form of nitrogen. To compensate , modern agriculture has been highly reliant on industrial nitrogen fertilizers to achieve maximum crop productivity. However, a great deal of fossil fuel is required for the production and delivery of nitrogen fertilizer. Moreover carbon dioxide (CO2) which is released during fossil fuel combustion contributes to the greenhouse effect and run off of nitrate leads to eutrophication of the waterways. Biological nitrogen fixation is an alternative to nitrogen fertilizer. It is carried out by prokaryotes using an enzyme complex called nitrogenase and results in atmospheric N2 being reduced into a form of nitrogen diazotrophic organisms and plants are able to use (ammonia). It is this process and its major players which will be discussed in this book. Biological Nitrogen Fixation is a comprehensive two volume work bringing together both review and original research articles on key topics in nitrogen fixation. Chapters across both volumes emphasize molecular techniques and advanced biochemical analysis approaches applicable to various aspects of biological nitrogen fixation. Volume 1 explores the chemistry and biochemistry of nitrogenases, nif gene regulation, the taxonomy, evolution, and genomics of nitrogen fixing organisms, as well as their physiology and metabolism. Volume 2 covers the symbiotic interaction of nitrogen fixing organisms with their host plants, including nodulation and symbiotic nitrogen fixation, plant and microbial "omics", cyanobacteria, diazotrophs and non-legumes, field studies and inoculum preparation, as well as nitrogen fixation and cereals. Covering the full breadth of current nitrogen fixation research and expanding it towards future advances in the field, Biological Nitrogen Fixation will be a one-stop reference for microbial ecologists and environmental microbiologists as well as plant and agricultural researchers working on crop sustainability.

Book Synopsis Resposta da soja à adubação nitrogenada na semeadura, em sistemas de plantio direto e convencional na região do cerrado by : I. C. Mendes
Download or read book Resposta da soja à adubação nitrogenada na semeadura, em sistemas de plantio direto e convencional na região do cerrado written by I. C. Mendes and published by . This book was released on 2000 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Desde 1980, a pesquisa tem mostrado a inutilidade da prática da adubação nitrogenada na semeadura da soja. Entretanto, com a expansão do plantio direto, na região do Cerrado, novamente surgiram dúvidas, por parte de alguns agricultores, sobre a eficiência do processo de inoculação e sobre a necessidade, ou não, da utilização de doses de "arranque" de adubo nitrogenado na semeadura, para superar possíveis problemas relacionados a imobilização do N e a competição inicial com plantas invasoras. Foram conduzidos, na Embrapa Cerrados, dois experimentos em áreas sob plantio direto (PD) e dois em áreas sob plantio convencional (PC) para avaliar a resposta da soja a pequenas doses de N na semeadura. Os tratamentos consistiram de quatro níveis de N (0, 20, 30, e 40 kg N.ha-1) na forma de uréia, aplicada, na semeadura, no sulco de plantio. Em ambas as áreas, a soja foi cultivada apos o milho. Todos os tratamentos foram inoculados com as estirpes SEMIA 5079 (CPAC 15) e SEMIA 5080 (CPAC 7) na proporção de 1 kg de inoculante para 50 kg de sementes. A adição de pequenas doses de adubo nitrogenado, na semeadura da soja, promoveu reduções significativas de ate 50% na sua nodulação inicial, avaliada aos 15 dias após a emergência. Apesar dessa redução, houve recuperação no número e na massa de nodulos na fase da floração. Independentemente do sistema de manejo, a adição de pequenas doses de N, na semeadura, não promoveu aumentos no rendimento de grãos da soja. Os resultados confirmam que não e necessário adicionar fertilizante nitrogenado na semeadura da soja.

Book Synopsis Nitrogen Fixation in Agriculture, Forestry, Ecology, and the Environment by : Dietrich Werner
Download or read book Nitrogen Fixation in Agriculture, Forestry, Ecology, and the Environment written by Dietrich Werner and published by Springer Science & Business Media. This book was released on 2005-10-24 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability has a major part to play in the global challenge of continued development of regions, countries, and continents all around the World and biological nitrogen fixation has a key role in this process. This volume begins with chapters specifically addressing crops of major global importance, such as soybeans, rice, and sugar cane. It continues with a second important focus, agroforestry, and describes the use and promise of both legume trees with their rhizobial symbionts and other nitrogen-fixing trees with their actinorhizal colonization. An over-arching theme of all chapters is the interaction of the plants and trees with microbes and this theme allows other aspects of soil microbiology, such as interactions with arbuscular mycorrhizal fungi and the impact of soil-stress factors on biological nitrogen fixation, to be addressed. Furthermore, a link to basic science occurs through the inclusion of chapters describing the biogeochemically important nitrogen cycle and its key relationships among nitrogen fixation, nitrification, and denitrification. The volume then provides an up-to-date view of the production of microbial inocula, especially those for legume crops.
Book Synopsis Symbiotic Nitrogen Fixation by : P. Graham
Download or read book Symbiotic Nitrogen Fixation written by P. Graham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the efforts of a large number of researchers we now have a better understanding of the ecology of rhizobia, environmental parameters affecting the infection and nodulation process, the nature of specificity, the biochemistry of host plants and microsymbionts, and chemical signalling between symbiotic partners. This volume gives a summary of current research efforts and knowledge in the field of biological nitrogen fixation. Since the research field is diverse in nature, this book presents a collection of papers in the major research area of physiology and metabolism, genetics, evolution, taxonomy, ecology, and international programs.

Download or read book A Comprehensive Survey of International Soybean Research - Genetics, Physiology, Agronomy and Nitrogen Relationships written by James E. Board and published by . This book was released on 2013 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean is the most important oilseed and livestock feed crop in the world. These dual uses are attributed to the crop's high protein content (nearly 40% of seed weight) and oil content (approximately 20%); characteristics that are not rivaled by any other agronomic crop. Across the 10-year period from 2001 to 2010, world soybean production increased from 168 to 258 million metric tons (54% increase). Against the backdrop of soybean's striking ascendancy is increased research interest in the crop throughout the world. Information in this book presents a comprehensive view of research efforts in genetics, plant physiology, agronomy, agricultural economics, and nitrogen relationships that will benefit soybean stakeholders and scientists throughout the world. We hope you enjoy the book.

Download or read book Soybean written by Minobu Kasai and published by BoD – Books on Demand. This book was released on 2019-02-20 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants are important for a permanent ecosystem, because in the ecological pyramid plants support all the other living organisms at the base. Very important organization is thought to be the integral process of resource, transport, partitioning, metabolism, and production, which involves yield, biomass, and productivity in plants. Accordingly, it is important to obtain more information about the knowledge concerning yield, biomass, and productivity in plants. Soybean is one of the main crops largely contributing to our life, which is thought to be connected to our ecosystem through the above-mentioned integral process. This book focuses on the soybean, and reviews and research concerning the yield, biomass, and productivity of soybean are presented herein. This text updates the book published in 2017. Although there are many difficulties, the main aim of this book is to present a basis for the above-mentioned integral processes of resource, transport, partitioning, metabolism, and production, which involves yield, biomass, and productivity in plants (soybean), and to understand what supports this basis and the integral process. It is hoped that this and the preceding book will be essential reads.

Book Synopsis The Rhizobiaceae by : Herman P. Spaink
Download or read book The Rhizobiaceae written by Herman P. Spaink and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Rhizobiaceae, Molecular Biology of Model Plant-Associated Bacteria. This book gives a comprehensive overview on our present molecular biological knowledge about the Rhizobiaceae, which currently can be called the best-studied family of soil bacteria. For many centuries they have attracted the attention of scientists because of their capacity to associate with plants and as a consequence also to specifically modify plant development. Some of these associations are beneficial for the plant, as is the case for the Rhizobiaceae subgroups collectively called rhizobia, which are able to fix nitrogen in a symbiosis with the plant hosts. This symbiosis results in the fonnation of root or stem nodules, as illustrated on the front cover. In contrast, several Rhizobiaceae subgroups can negatively affect plant development and evoke plant diseases. Examples are Agrobacterium tumefaciens andA. rhizogenes which induce the formation of crown galls or hairy roots on the stems of their host plants, respectively (bottom panels on front cover). In addition to the obvious importance of studies on the Rhizobiaceae for agronomy, this research field has resulted in the discovery of many fundamental scientific principles of general interest, which are highlighted in this book. To mention three examples: (i) the discovery of DNA transfer of A.
