Download or read book The European Nitrogen Assessment written by Mark A. Sutton and published by Cambridge University Press. This book was released on 2011-04-14 with total page 665 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presenting the first continental-scale assessment of reactive nitrogen in the environment, this book sets the related environmental problems in context by providing a multidisciplinary introduction to the nitrogen cycle processes. Issues of upscaling from farm plot and city to national and continental scales are addressed in detail with emphasis on opportunities for better management at local to global levels. The five key societal threats posed by reactive nitrogen are assessed, providing a framework for joined-up management of the nitrogen cycle in Europe, including the first cost-benefit analysis for different reactive nitrogen forms and future scenarios. Incorporating comprehensive maps, a handy technical synopsis and a summary for policy makers, this landmark volume is an essential reference for academic researchers across a wide range of disciplines, as well as stakeholders and policy makers. It is also a valuable tool in communicating the key environmental issues and future challenges to the wider public.

Download or read book Nitrogen in the Environment Sources Problems and Management written by R.F. Follett and published by Gulf Professional Publishing. This book was released on 2001-12-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment. The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.

Download or read book Diagnosis of the Nitrogen Status in Crops written by Gilles Lemaire and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing a link between theoretical and applied aspects of plant nutrition and agriculture, this book introduces new concepts in plant nutrition. It shows how these can be applied in order to assess the nitrogen status in crops and to improve nitrogen nutrition through optimized N fertilization management. In this way economic benefits can be obtained, while at the same time preventing detrimental effects on the environment. The main agricultural crops - grasses, wheat, barley, Durum wheat, maize, sorghum, grain legumes and potatoes - are covered. The book will be an invaluable source for agronomists.
Download or read book Physical and Physiological Forest Ecology written by Pertti Hari and published by Springer Science & Business Media. This book was released on 2012-12-24 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces a holistic synthesis of carbon and nitrogen fluxes in forest ecosystems from cell to stand level during the lifetime of trees. Establishing that metabolism and physical phenomena give rise to concentration, pressure and temperature differences that generate the material and energy fluxes between living organisms and their environment. The editors and authors utilize physiological, physical and anatomical background information to formulate theoretical ideas dealing with the effects of the environment and the state of enzymes, membrane pumps and pigments on metabolism. The emergent properties play an important role in the transitions from detailed to more aggregate levels in the ecosystem. Conservation of mass and energy allow the construction of dynamic models of carbon and nitrogen fluxes and pools at various levels in the hierarchy of forest ecosystems.
Download or read book Plants at the Margin written by R. M. M. Crawford and published by Cambridge University Press. This book was released on 2008-03-20 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Margins are by their very nature environmentally unstable - does it therefore follow that plant populations adapted for life in such areas will prove to be pre-adapted to withstand the changes that may be brought about by a warmer world? Biogeography, demography, reproductive biology, physiology and genetics all provide cogent explanations as to why limits occur where they do, and the purpose of this book is to bring together these different avenues of enquiry. Crawford's numerous beautiful illustrations of plants in their natural habitats remind us that the environment remains essential to our understanding of plants and their function. This book is suited to students, researchers and anyone with an interest in the impact of climate change on our world.

Download or read book Inorganic Nutrition of Plants written by F.C. Steward and published by Elsevier. This book was released on 2012-12-02 with total page 830 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Physiology, Volume III: Inorganic Nutrition of Plants deals with the inorganic nutrition and metabolism of plants. The book explores the role of elements, other than carbon, hydrogen, and oxygen, which are essential to, or used by, plants in their vital processes. It summarizes the knowledge about mineral nutrition of plants and presents a philosophy of plant nutrition in general. This volume is organized into six chapters and begins with a brief history of mineral nutrition of plants, as well as the media from which plants draw their nutrients, such as the soil and artificial culture medium. The book then discusses the requirements for specific elements, the symptoms incurred by their deficient supply, and the evidence that a given element can be considered essential. The next chapters focus on the inorganic nutrition of microorganisms, general functions of the essential nutrient elements, and the biological situations in which elementary nitrogen is converted to the organic form. The book concludes by analyzing the soil as a complex biological system and its implication for the interpretation of the nutrition of higher plants. This book is a valuable resource for those interested in plant nutrition and plant physiology.
