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.

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.

Download or read book China's Soil Pollution and Degradation Problems written by Claudio O. Delang and published by Taylor & Francis. This book was released on 2017-05-18 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: China’s air pollution is infamous. The haze can make it impossible to see buildings across the street, and the pollution forces schools to close and creates health and morbidity problems, in addition to tremendous environmental degradation. However, China also faces another important environmental problem, which is less well-known to the public: that of soil degradation and pollution. This book provides an overview of the problems related to soil degradation and pollution throughout China, examining how and why current policy has fallen short of expectation. It also examines the challenges faced by policy makers as they attempt to adopt sustainable practices alongside a booming and ever-expanding economy. China's Soil Pollution and Degradation Problems utilizes grey literature such as newspaper articles, NGO reports and Chinese government information alongside academic studies in order to provide an extensive review of the challenges faced by grassroots organizations as they tackle environmental policy failings throughout China. This book will be of great interest to students of environmental pollution and contemporary Chinese studies looking for an introduction to the topics of soil pollution and soil degradation, and for researchers looking for an extensive list of sources and analysis of China's environmental problems more broadly.

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.

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.

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.

Download or read book Principles of Sustainable Soil Management in Agroecosystems written by Rattan Lal and published by CRC Press. This book was released on 2013-06-10 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the use of high-level soil management technology, Africa could feed several billion people, yet food production has generally stagnated since the 1960s. No matter how powerful the seed technology, the seedling emerging from it can flourish only in a healthy soil. Accordingly, crop yields in Africa, South Asia, and the Caribbean could be doubled or tripled through adoption of technologies based on laws of sustainable soil management. Principles of Sustainable Soil Management in Agroecosystems describes the application of these laws to enhance ecosystem services while restoring degraded soils and promoting sustainable use. With chapters contributed by world-class soil scientists, ecologists, and social scientists, this book outlines critical changes in management of agricultural soils necessary to achieve food security and meet the food demands of the present and projected future population. These changes include conversion to no-till and conservation agriculture; adoption of strategies of integrated nutrient management, water harvesting, and use of drip sub-irrigation; complex cropping/farming systems such as cover cropping and agroforestry; and use of nano-enhanced fertilizers. The book is based on the premise that it is not possible to extract more from a soil than what is put into it without degrading its quality. The strategy is to replace what is removed, respond wisely to what is changed, and be pro-active to what may happen because of natural and anthropogenic perturbations. The chapters, which exemplify these ideas, cover a range of topics including organic farming, soil fertility, crop-symbiotic soil microbiota, human-driven soil degradation, soil degradation and restoration, carbon sink capacity of soils, soil renewal and sustainability, and the marginality principle.
