Book Synopsis Marine Nitrogen Fixation by : Jonathan P. Zehr
Download or read book Marine Nitrogen Fixation written by Jonathan P. Zehr and published by Springer Nature. This book was released on 2021-04-02 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to serve as a centralized reference document for students and researchers interested in aspects of marine nitrogen fixation. Although nitrogen is a critical element in both terrestrial and aquatic productivity, and nitrogen fixation is a key process that balances losses due to denitrification in both environments, most resources on the subject focuses on the biochemistry and microbiology of such processes and the organisms involved in the terrestrial environment on symbiosis in terrestrial systems, or on largely ecological aspects in the marine environment. This book is intended to provide an overview of N2 fixation research for marine researchers, while providing a reference on marine research for researchers in other fields, including terrestrial N2 fixation. This book bridges this knowledge gap for both specialists and non-experts, and provides an in-depth overview of the important aspects of nitrogen fixation as it relates to the marine environment. This resource will be useful for researchers in the specialized field, but also useful for scientists in other disciplines who are interested in the topic. It would provide a possible text for upper division classes or graduate seminars.

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.

Book Synopsis Plant Microbe Symbiosis: Fundamentals and Advances by : Naveen Kumar Arora
Download or read book Plant Microbe Symbiosis: Fundamentals and Advances written by Naveen Kumar Arora and published by Springer Science & Business Media. This book was released on 2013-08-15 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant microbe interaction is a complex relationship that can have various beneficial impacts on both the communities. An urgent need of today’s world is to get high crop yields in an ecofriendly manner. Utilization of beneficial and multifaceted plant growth promoting (PGP) microorganisms can solve the problem of getting enhanced yields without disturbing the ecosystem thus leading to sustainability. For this to achieve understanding of the intricate details of how the beneficial microbes form associations with the host plant and sustain that for millions of years must be known. A holistic approach is required wherein the diversity of microbes associated with plant and the network of mechanisms by which they benefit the host must be studied and utilized. ‘Plant Microbe Symbiosis – Fundamentals and Advances’ provides a comprehensive understanding of positive interactions that occur between plant and microorganisms and their utilization in the fields. The book reviews the enormous diversity of plant associated microbes, the dialog between plant-microbes-microbes and mechanisms of action of PGP microbes. Utilization of PGPRs as nutrient providers, in combating phytopathogens and ameliorating the stressed and polluted soils is also explained. Importantly, the book also throws light on the unanswered questions and future direction of research in the field. It illustrates how the basic knowledge can be amalgamated with advanced technology to design the future bioformulations.

This book was released on 2013-03-09 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical fertilizers have had a significant impact on food production in the recent past, and are today an indispensable part of modern agriculture. On the other hand, the oil crisis of the 1970s and the current Middle East problems are constant reminders of the vulnerability of our fossil fuel dependent agriculture. There are vast areas of the developing world where N fertilizers are neither available nor affordable and, in most of these countries, balance of payment problems have resulted in the removal of N fertilizer subsidies. The external costs of environmental degradation and human health far exceed economic concerns. Input efficiency of N fertilizer is one of the lowest and, in turn, contributes substantially to environmental pollution. Nitrate in ground and surface waters and the threat to the stability of the ozone layer from gaseous oxides of nitrogen are major health and environmental concerns. The removal of large quantities of crop produce from the land also depletes soil of its native N reserves. Another concern is the decline in crop yields under continuous use of N fertilizers. These economic, environmental and production considerations dictate that biological alternatives which can augment, and in some cases replace, N fertilizers must be exploited. Long-term sustainability of agricultural systems must rely on the use and effective management of internal resources. The process of biological nitrogen fixation offers and economically attractive and ecologically sound means of reducing external nitrogen input and improving the quality and quantity of internal resources. In this book, we outline sustainability issues that dictate an increased use of biological nitrogen fixation and the constraints on its optimal use in agriculture.

Book Synopsis Stable Isotopes in Plant Nutrition, Soil Fertility and Environmental Studies by : International Atomic Energy Agency
Download or read book Stable Isotopes in Plant Nutrition, Soil Fertility and Environmental Studies written by International Atomic Energy Agency and published by . This book was released on 1991 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of a symposium jointly organized by the IAEA and FAO, Vienna, 1-5 October 1990. The objective of the symposium was to evaluate progress in the use of stable isotopes to examine various aspects of soil fertility and plant nutrition and some environmental problems, the potential and limitations of existing methods, and possibilities for further development. The meeting focused on the site level rather than the landscape level and, more specifically, on soil-plant relations, although landscape environmental aspects were also examined. The underlying theme was an assessment of current and possible future approaches to two problems of concern: how to increase or sustain productivity with minimum inputs, and how to limit environmental damage due to inappropriate land management and to industry.
