Book Synopsis Nitrogen in Soils of China by : Zhu Zhao-liang
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 Synopsis The Red Soils of China by : Michael Wilson
Download or read book The Red Soils of China written by Michael Wilson and published by Springer Science & Business Media. This book was released on 2004-05-26 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The red soils of China are typical in their chemical, physical and mineralogical characteristics of red soils in other tropical and sub-tropical areas of the world, particularly in South America, Africa and south-east Asia. For the most part, these soils are highly weathered and inherently infertile. They are acidic, nutrient deficient, poor in organic matter and have a low water-holding and supplying capacity. They cannot sustain arable cropping systems without the most careful management and are highly susceptible to soil erosion, particularly on sloping land. It is the purpose of this book to present recent research showing how the problems associated with using the red soils in China for sustainable agricultural production can be overcome, using a variety of traditional and novel approaches. In principle, these approaches should be useful in other tropical and sub-tropical countries faced with the problem of making the best use of their fragile red soil resources. The term "in principle" is used deliberately because, of course, the different red soil countries invariably operate within dissimilar socio-economic frameworks. At the present time, China may be considered to be in the process of an "industrial revolution", rather like that that took place in Britain in the late eighteenth and early nineteenth centuries.

Book Synopsis Atmospheric Reactive Nitrogen in China by : Xuejun Liu
Download or read book Atmospheric Reactive Nitrogen in China written by Xuejun Liu and published by Springer Nature. This book was released on 2019-10-04 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric reactive nitrogen (N) emissions, as an important component of global N cycle, have been significantly altered by anthropogenic activities, and consequently have had a global impact on air pollution and ecosystem services. Due to rapid agricultural, industrial, and urban development, China has been experiencing an increase in reactive N emissions and deposition since the late 1970s. Based on a literature review, this book summarizes recent research on: 1) atmospheric reactive N in China from a global perspective (Chapter 1); 2) atmospheric reactive N emissions, deposition and budget in China (Chapters 2-5); 3) the contribution of atmospheric reactive N to air pollution (e.g., haze, surface O3, and acid deposition) (Chapters 6-8); 4) the impacts of N deposition on sensitive ecosystems (e.g., forests, grasslands, deserts and lakes) (Chapters 9-12); and 5) the regulatory strategies for mitigation of atmospheric reactive N pollution from agricultural and non-agricultural sectors in China (Chapters 13-14). As such it offers graduate students, researchers, educators in agricultural, ecological and environmental sciences, and policy makers a glimpse of the environmental issues related to reactive N in China .
Book Synopsis Shifting Ground by : Peter H. Lindert

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 Atmospheric Ammonia by : Mark Sutton
Download or read book Atmospheric Ammonia written by Mark Sutton and published by Springer Science & Business Media. This book was released on 2008-12-30 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic emissions of ammonia cause a host of environmental impacts, including loss of biodiversity, soil acidification and formation of particulate matter in the atmosphere. Under the auspices of the UNECE Convention on Long Range Transboundary Air Pollution, around 80 international experts met to review the state of scientific knowledge. This book reports their analysis. It concludes that threshold levels for ammonia effects have been underestimated and sets new values, it assesses the independent evidence to verify reported reductions in regional ammonia emissions, and it reviews the uncertainties in modelling ammonia, both in "hot spots" and at the regional scale.
Book Synopsis Soil Nitrogen Uses and Environmental Impacts by : Rattan Lal
Download or read book Soil Nitrogen Uses and Environmental Impacts written by Rattan Lal and published by CRC Press. This book was released on 2018-03-15 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen (N) is potentially one of the most complex elements on the Earth. It is necessary for all biological activity, but creates negative impacts on water and air quality. There is a balancing act between deficiency and surplus and the forms of N available further complicate our understanding of the dynamics. Biological fixation provides some plants with N supply while others are totally dependent upon N being available in the soil profile for the roots to extract. Nevertheless, the demand for N will increase because the human population with its increasing growth requires more protein and thus more N. Understanding the global N cycle is imperative to meeting current and future nitrogen demands while decreasing environmental impacts. This book discusses availability, production, and recycling of N in air, water, plants, and soils. It features information on N impacts to soil and water quality, management of N in agroecosystems, and techniques to maximize the use efficiency while minimizing the risks of leakage of reactive N into the environment. This volume in the Advances in Soil Science series is specifically devoted to availability, production, and recycling of N with impact on climate change and water quality, and management of N in agroecosystems in the context of maximizing the use efficiency and minimizing the risks of leakage of reactive N (NO-3, N¬2O) into the environment.
