Book excerpt: Nitrate Handbook: Environmental, Agricultural, and Health Effects provides an overview of the entire nitrate cycle and the processes influencing nitrate transformation. It clearly identifies the role of nitrate as an essential nutrient in plant growth, food preservation, and human health. Using the most up-to-date knowledge and research, this handbook illustrates how the steadily increasing human population and demand for food, which results in higher amounts of nitrate needed by soils, makes new regulations on the management and usage of nitrates a high priority. A detailed explanation concerning the discrepancies between the public’s perception of nitrate’s harm versus the reality of its human health benefits is given via a balanced and evidence-based approach. All questions pertaining to the influences of nitrate and its derivatives on plant physiology and human health are explored in depth. This comprehensive resource with contributions from distinguished researches in the field is a must-have for professionals and students who study and work with nitrates. Features: Includes in depth discussion on the wide spectrum of nitrate present in the environment. Focuses on the progress made on nitrate research and its importance. Answers all questions about nitrate and its derivatives’ influences on plant physiology and human health. Enables decision makers and public authorities to manage social concerns Compiles in one resource the findings of many distinguished researchers in the field.
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 Nutrient Dynamics and Retention in Land Water Ecotones of Lowland Temperate Lakes and Rivers written by A. Hillbricht-Ilkowska and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotones, or boundary zones between land and inland waters (such as lakes, streams and rivers), are the principal routes for transport of organic matter and nutrients across landscapes via physical and biological vectors. The ecotone is the place of cumulation and transformation of in situ production as well as of allochthonous material from adjacent aquatic and terrestrial systems. The ecotype functions as an important barrier or filter for principal nutrients, such as phosphorus and nitrogen, responsible for the eutrophication and degradation of surface waters. Intensive forest cutting, agriculture, pollution and bank regulation, urbanization and hydrotechnical constructions seriously endanger the ecotone systems and damage their protective function. It is vital to develop a scientific understanding of the behaviour of phosphorus and nitrogen in these transitional boundary habitats. Such an understanding is important for the rational protection, management and restoration of ecotones connected with lakes and rivers. The importance of nutrient cycling and retention is discussed from the point of view of ecotone function, management and reconstruction in order to sustain its protective role for water bodies. Various types of land/water transitory zones are discussed: wetlands, lake littoral systems, riparian zones of rivers, streams and brooks, the contact zones between groundwater and surface waters of lakes and rivers, air--water interfaces, and patch/ecotone structures in watersheds.

Download or read book Nitrate Agriculture and the Environment written by T. M. Addiscott and published by CABI. This book was released on 2005 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is widespread public concern about the effects of nitrate derived from farming on water quality and public health. But research on nitrate during the past decade has revealed wide discrepancies between public perceptions and reality. The main problems from nitrate are ecological changes in coastal and estuarine waters and nitrous oxide in the atmosphere. This gas, largely derived from nitrate, is a threat to the ozone layer in the stratosphere and is also a greenhouse gas. This book builds on Farming, Fertilizers and the Nitrate Problem (CABI, 1991) by Addiscott, Whitmore and Powlson but has been restructured to take account of new developments and to bring out more clearly the role of politicians and economists in the 'nitrate problem'.

Download or read book Riverine Ecosystem Management written by Stefan Schmutz and published by Springer. This book was released on 2018-05-08 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.
