Product Description
Inositol phosphates are a group of organic compounds found widely in the natural environment. They are important in agriculture because they constitute most of the phosphorus in grain seeds, but they cannot be digested by some animals. As a result, considerable research has been directed
towards improving the digestibility of inositol phosphates in animal diets. Inositol phosphates are also abundant in soils and water bodies, yet a clear understanding of their behavior in the environment remains elusive. This is surprising given the importance of phosphorus in the nutrition of both
terrestrial and aquatic ecosystems. Written by leading experts, this book brings together critical reviews on inositol phosphates in agriculture, ecology, and the environment. The sixteen chapters cover a diverse range of topics, including the synthesis and hydrolysis of inositol phosphates, their
role in animal nutrition, and their fate in soils and aquatic ecosystems. It will prove valuable to a wide readership in the agricultural and biological sciences, and will serve as a unique reference source on this emerging topic.

Product Description
Research is never free of pressures and constraints and to understand its results properly these have to be assessed and analyzed. In agriculture, research into biotechnology and GMOs as well as pesticides and herbicides is big business - agribusiness. This book looks at the crucial roles of funding and the political context on the research agenda and its results in agricultural development. It provides the first critical evaluation of the participatory methods now widely used, and explores the ways in which research into biotechnology have reflected the interests of the various parties involved.

Product Description
Since 1998, the Dutch Ministry of Agriculture, Nature Management and Food Quality (LNV) promotes development-orientated agricultural and environmental research and strengthening of North-South partnerships through its International Cooperation (DLO-IC) research programme. By 2005, some 70 collaborative North-South projects had been carried out. All science groups in Wageningen University and Research Centre (WUR) were involved in the implementation of the programme and at least half the projects and activities undertaken were directly related to Rural Development and Sustainable Agriculture (RDSA).
Facing new challenges with respect to sustainable development strategies for low-income countries, related to global environmental change and globalization of markets, an interdisciplinary Wageningen research group set out to draw lessons from the DLO-IC projects of the last eight years, stimulate discussion and support identification of a future research agenda for RDSA. In that process, special emphasis was given to lessons for future thinking about the contribution of agriculture to: 1) poverty alleviation and rural livelihoods; 2)food security, human nutrition and health; 3) environmental sustainability and natural resource management.
In discussing the way ahead, a number of major research challenges, as well as policy questions are outlined. These include the interrelations between climate change and food security and environmental degradation, increased demand for biofuels and animal feed, and competing claims on natural resources, and rural development and livelihood strategies in low-income countries.

Description: The turn of the millennium from the twentieth to the twenty-first century provides an occasion to review our understanding of a biological process, biological nitrogen fixation, that is of prime importance for the continued survival of mankind. This process has provided a basis for maintaining soil fertility since the beginning of organised agriculture, yet its very existence was confirmed only just over a century ago. In the intervening years, an enormous intellectual effort has dispersed much of the mystery surrounding biological nitrogen fixation. Biological fixation is widely exploited in agriculture, as are nitrogen fertilisers prepared for the last hundred years under extreme conditions of temperature and pressure. However, despite all our efforts, the fundamental nature of the reactions involved at the heart of the biological process remain unknown.
This book aims to describe what we have learned in the last one hundred years or so about biological nitrogen fixation, about what its chemistry appears to be, and how it is applied in agriculture. This ambitious objective has not been attempted recently. It is aimed at students and those who wish to enter these very challenging areas of research, and who need to learn the state of the art at the turn of the millennium.

Description:
This book is the self-contained fourth volume of a seven-volume comprehensive series on nitrogen fixation. The outstanding aspect of this book is the integration of basic and applied work on biological nitrogen fixation in the fields of agriculture, forestry, and ecology in general. Nowadays, the concept of sustainability, which originated in [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]and land use, is reaching many other areas of society and industry. 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 [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]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 [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل] 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 [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]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 [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]crops. No other available work provides the up-to-date and [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل] of this volume, which is intended to serve as an indispensable [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل] for academic, government, and industrial scientists working in the applied areas of agronomy, plant breeding, plant nutrition, ecology, and forestry as well as those in the basic science areas of plant physiology, soil [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل], and related environmental disciplines. This volume will be an invaluable tool for students entering this challenging area of research and will provide science administrators with ready access to vital relevant information.

Description:
This book is the stand-alone final volume of a comprehensive series covering the basic and applied science relating to nitrogen fixation. It addresses the most important nitrogen-fixing symbiosis of all – that between legumes and their root-nodule bacteria – and therefore deals with the properties and behaviour of both macro- and micro-symbiont. The coverage is comprehensive, beginning with the extent of the symbiosis and how it may have arisen in the geological past. It considers how legumes select the root-nodule bacteria they allow to form nodules on their roots and the intricate series of signals to be exchanged between legume and bacteria for infection to occur. The immense progress in understanding the genetic systems in the bacteria necessary for nodulation is now being replicated in a rapidly increasing understanding of the required systems in the legumes. The cell biology of the processes of both infection and nodule development is analysed and leads to a parallel assessment of the biochemical processes in carbon and nitrogen metabolism required for successful nitroogen fixation by the symbiotic bacteroid. Attention is given to the ways in which the nodule has solved the conundrum of providing enough O2 for energy generation to drive nitrogen fixation without either inactivating the O2-sensitive nitrogenase or creating damaging reactive oxygen species. The volume also covers the basic physiology of the variety of root-nodule bacteria infecting legumes, as well as looking at the renewed controversy about the chemical form(s) of nitrogen exported to the legume. Successful exploitation of the legume symbiosis in agriculture, horticulture, and forestry demands an understanding of the ecology of the root-nodule bacteria – particularly what makes for a successful inoculant strain for legume introduction to agricultural systems. Then, there is a requirement for inoculation technology to both successfully deliver viable bacteria to the root surface and facilitate nodulation. These practical aspects are thoroughly covered in the volume, with a final chapter assessing how the massive amount of recent information can be exploited in matching host and microsymbiont for the wide variety of environments in which they are needed in our production systems.

Description:
This book is the self-contained sixth volume of a comprehensive series on nitrogen fixation. It presents the state-of-the-art in regards to actinorhizal symbioses. Like [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل], actinorhizal plants form root nodules that host nitrogen-fixing soil [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]. However, because the macrosymbionts are, with one exception, woody plants rather than crop plants, actinorhizal symbioses are less well-known than legume symbioses to which they are phylogenetically related. Actinorhizal plants come from eight different families. They can grow on marginal soils by virtue of these symbioses and are used extensively in reforestation, soil reclamation, and desert agroforestry. The [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]of the involved host plants poses a variety of challenges to the actinorhizal symbiosis and results in interesting strategies, for example, to cope with the O2 dilemma or nutrient [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]between plant and bacterium. The actinorhizal micro-symbionts are Gram-positive actinomycetes of the genus Frankia. The inability to culture several actinorhizal microsymbionts has led to the development of diverse molecular strategies for strain identification. This volume includes chapters that deal with all these aspects of the symbiosis and both symbionts plus their ecological role and use. Other chapters tackle the [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]distribution of different actinorhizal plants and their microsymbionts and how this impacts the question of co-[فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]of the micro- and macrosymbionts as well as comparing the actinorhizal and leguminous symbioses. No other book provides the up-to-date and in-depth coverage of this volume, which is intended to serve as an indispensable reference work for academic, governmental, and industrial scientists working in this area, to introduce students to the global importance of this association, and to provide science administrators with ready access to vital relevant information.

Chalcogen-nitrogen chemistry involves the study of compounds that exhibit a linkage between nitrogen and sulfur, selenium or tellurium atoms. Such studies have both fundamental and practical importance. A Guide to Chalcogen-Nitrogen Chemistry examines the role of chalcogen-nitrogen compounds in areas ranging from solid-state inorganic chemistry to biochemistry. The discussion covers fundamental questions concerning the bonding in electron-rich systems, as well as potential practical applications of polymers and materials with novel magnetic or electrical properties. This book is the only account of this important topic to appear in the last twenty-five years, and coupled with its extensive literature coverage of very recent developments, this comprehensive guide is essential for anyone working in the field. The treatment is unique in providing a comparison of sulfur, selenium and tellurium systems, with an approach intended to emphasize general concepts that will be helpful to the non-specialist. Each chapter is designed to be self-contained, and there are extensive cross-references between chapters.

Description:
Good management practices for carbon and nitrogen are vital to crop productivity and soil sustainability, as well as to the reduction of global greenhouse gases and environmental pollution. Since the 1950's, mathematical models have advanced our understanding of carbon and nitrogen cycling at both the [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]- and macro-scales. However, many of the models are scattered in the literature, undergo constant modification, and similar models can have different names. Modeling Carbon and Nitrogen Dynamics for Soil Management clarifies the confusion by presenting a systematic summary of the various models available. It provides information about strengths and weaknesses, level of complexity, easiness of use, and application range of each model. In nineteen chapters, internationally known model developers and users update you on the current status and future direction of carbon and nitrogen modeling. The book's coverage ranges from theoretical comparison of models to application of models to soil management problems, from laboratory applications to field and watershed scale applications, from short-term [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل] to long-term prediction, and from DOS-based [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]to Object-Oriented and Graphical Interface designs. With this broad scope, [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]Carbon and Nitrogen Dynamics for Soil Management provides the tools to manage complex carbon/nitrogen processes effectively.

Description:
This book focuses on the very latest developments in our understanding of how plants use light energy and fixed carbon to assimilate nitrate and ammonium into the organic compounds required for growth. From the partitioning of organic nitrogen within the photosynthetic apparatus, through the primary processes of reduction of nitrate and nitrite and the assimilation of ammonium and its [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]in photorespiration, the complex interactions inherent in the crosstalk between carbon and [فقط الأعضاء المسجلين والمفعلين يمكنهم رؤية الوصلات . إضغط هنا للتسجيل]assimilation are considered and exciting new developments such as nitric oxide production evaluated. Attention is paid throughout to the close coordination of photosynthetic and respiratory processes in nitrogen assimilation. Emerging concepts of the interdependence of chloroplasts and mitochondria are described, and essential communication, transport and signalling processes are highlighted.
