Download or read book Nitrogen in Soils of China written by Zhu Zhao-liang and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of soil nitrogen has long been an active field, but it was generally pivoted on agricultural and forestry production, and animal husbandry. With the rapid increase in the use of fertilizer nitrogen, more attention has been paid to the rela tionship between nitrogen management and environmental quality and human of soil nitrogen has become more comprehensive with health. In addition, the study the development of related sciences. The quantitative study of the processes in nitrogen cycling and their interrelationships has been an important part of this project and has attracted the attention of scientists allover the world. Nitrogen is one of the most important nutrients for plant growth and the applica tion of fertilizer nitrogen is playing an important role in agricultural production. The annual consumption of fertilizer nitrogen in the world has reached 70 million tons, and China has an annual consumption of more than 15 million tons and is the largest fertilizer nitrogen consumer in the world. However, the efficiency of nitro gen fertilizer is low and losses are large. It is estimated that nitrogen losses from agriculture in our country can be as high as 40-60% of the nitrogen applied. Some of the lost nitrogen enters the atmosphere and contributes to the greenhouse effect and some enters water bodies to pollute the water.

Book excerpt: Peter Lindert evaluates environmental concerns about soil degradation in two very large countries—China and Indonesia—where anecdotal evidence has suggested serious problems. In this book Peter Lindert evaluates environmental concerns about soil degradation in two very large countries—China and Indonesia—where anecdotal evidence has suggested serious problems. Lindert does what no scholar before him has done: using new archival data sets, he measures changes in soil productivity over long enough periods of time to reveal the influence of human activity. China and Indonesia are good test cases because of their geography and history. China has been at the center of global concerns about desertification and water erosion, which it may have accelerated with intense agriculture. Most of Indonesia's lands were created by volcanoes and erosion, and its rapid deforestation and shifting slash-burn agriculture have been singled out for international censure. Lindert's investigation suggests that human mismanagement is not on average worsening the soil quality in China and Indonesia. Human cultivation lowers soil nitrogen and organic matter, but has offsetting positive effects. Economic development and rising incomes may even lead to better soil. Beyond the importance of Lindert's immediate findings, this book opens a new area of study—quantitative soil history—and raises the standard for debating soil trends.

Book Synopsis Gaseous Loss of Nitrogen from Plant-Soil Systems by : J.R. Freney

This book was released on 2013-04-17 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: A growing interest has been shown recently in the dymanics of nitrogen in agricultural and natural ecosystems. This has been caused by increasing demands for food and fibre by a rapidly expanding world population, and by a growing concern that increased land clearing, cultivation and use of both fertilizer and biologically fixed nitrogen can have detrimental effects on the environment. These include effects on water quality, eutrophication of surface waters and changes in atmospheric composition all caused by increased cycling of nitrogenous compounds. The input and availability of nitrogen frequently affects the productivity of farming systems more than any other single management factor, but often the nitrogen is used inefficiently. Much of the fertilizer nitrogen applied to the soil is not utilised by the crop: it is lost either in solution form, by leaching of nitrate, or in gaseous forms as ammonia, nitrous oxide, nitric oxide or dinitrogen. The leached nitrate can contaminate rivers and ground waters, while the emitted ammonia can contaminate surface waters or combine with atmospheric sulfur dioxide to form aerosols which affect visibility, health and climate. There is also concern that increased evolution of nitrous oxide will deplete the protective ozone layer of the stratosphere. The possibility of a link between the intensity of agricultural use of nitrogen, nitrous oxide emissions and amounts of stratospheric ozone has focussed attention on these interactions.

Book Synopsis Natural Capital and Human Economic Survival, Second Edition by : Thomas Prugh
Download or read book Natural Capital and Human Economic Survival, Second Edition written by Thomas Prugh and published by CRC Press. This book was released on 1999-05-20 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most people love nature and consider themselves environmentalists, but nature isn't just pretty and lovable, it is indispensable to our survival and economic activity. That is the most compelling reason for environmental protection. The conventional economic wisdom views land (natural capital) as a small part of the economy, along with capital, labor, technology and so on. The authors argue that this is backwards: that the economy nests within the environment (land) and not the other way around. The authors give a brief history of the origins of conventional economic wisdom and critique it from a the standpoint of ecological economics. They explain what natural capital -our life support system - is and does, and describe the severe strains that have been put on it. They conclude with some policy options, such as green taxes and suggestions for personal action that would conserve natural capital and thus make conserve resources for present and future generations. Natural Capital and Human Economic Survival is written for environmentalists, environmental studies majors and anyone concerned about the flaws of mainstream economics - how it has led us into unsustainable ways of living - and who would like to learn about alternatives that are more sustainable.

Book excerpt: The most complete, nonpartisan source of information on this hot agronomic topic available today, this book brings together a diverse group of papers and data to resolve the debate between sedimentologists and soil scientists and agronomists over whether the effects of soil erosion on carbon and atmospheric CO2 is beneficial or destructive. Divided into four sections, it offers data on how soil erosion affects soil, water, and air quality. Topics include mineralization rate, inundation, sediment deposition, and global warming potential, as well as carbon dioxide, methane, and nitrous oxide emissions, and the implications of soil erosion on the global carbon cycle and carbon budget.
Book Synopsis Restoration and Development of the Degraded Loess Plateau, China by : Atsushi Tsunekawa
Download or read book Restoration and Development of the Degraded Loess Plateau, China written by Atsushi Tsunekawa and published by Springer Science & Business Media. This book was released on 2013-08-23 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents state-of-the-art scientific evidence and technological innovations to restore lands on the Loess Plateau of China, known worldwide for its serious land degradation and desertification problems. Supported by a rapidly developing Chinese economy and the dissemination of effective technology, the Grain-for-Green Project and Western Development Action launched by the Chinese government have resulted in successful ecological restoration and protection over the past 30 years. These programs have contributed not only to conservation of soil and water, but also to economic development. At the same time, however, these developmental interventions have brought new challenges that have not yet been fully addressed. The book describes (1) case studies of success and failure in practice, including rare success stories of combating desertification; (2) technical issues such as erosion control and breeding of stress-tolerant plant species, and socioeconomic measures taken by the Chinese government and lending policies with support from the World Bank; and (3) comprehensive measures against desertification, such as water and wind erosion, salinization, and deforestation. This volume is recommended for researchers and students above the undergraduate level in diverse fields including soil science, rural engineering, social technology and civil engineering, biology, ecology, climatology, physical and human geography, and developmental economics, among others. It also serves as a valuable resource for engineers, government officials, and NPOs and NGOs involved in afforestation, ecological restoration, combating desertification, disaster prevention, and sustainable rural development.
Book Synopsis Theory and Practice of Soil Loss Control in Eastern China by : Yu Zhang
Download or read book Theory and Practice of Soil Loss Control in Eastern China written by Yu Zhang and published by Springer. This book was released on 2011-06-09 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the 1998 flood of the Yangtze River, one of the world’s most important rivers, environmental experts realized that, to control flooding, much more attention must be paid to vegetation cover on bare lands, thin forest land, and shrub-covered land in mountain areas. In 1999, an environmental monitoring project of the forests in 11 provinces of the Yangtze River basin was undertaken. This book reports on soil loss prediction and the successful practices of soil loss control in eastern China in recent years.
Book Synopsis Agriculture and the Nitrogen Cycle by : Arvin Mosier
Download or read book Agriculture and the Nitrogen Cycle written by Arvin Mosier and published by Island Press. This book was released on 2013-04-10 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is an essential element for plant growth and development and a key agricultural input-but in excess it can lead to a host of problems for human and ecological health. Across the globe, distribution of fertilizer nitrogen is very uneven, with some areas subject to nitrogen pollution and others suffering from reduced soil fertility, diminished crop production, and other consequences of inadequate supply. Agriculture and the Nitrogen Cycle provides a global assessment of the role of nitrogen fertilizer in the nitrogen cycle. The focus of the book is regional, emphasizing the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) in Kampala, Uganda, that brought together the world's leading scientists to examine and discuss the nitrogen cycle and related problems. It contains an overview chapter that summarizes the group's findings, four chapters on cross-cutting issues, and thirteen background chapters. The book offers a unique synthesis and provides an up-to-date, broad perspective on the issues of nitrogen fertilizer in food production and the interaction of nitrogen and the environment.
