Book Description
Farmers in industrialized countries are met with the simultaneous demands of managing plant nutrients in order to maintain high crop productivity, while minimizing environmental impact and maintaining soil quality. This book identifies the key issues associated with managing soil quality. It discusses solutions to these challenges, by addressing key soil attributes and management, and how these affect, or can be used to improve, soil quality. Topics covered include retaining soil organic matter, supporting soil biodiversity, reducing subsoil compaction and combating erosion.

Book Description
Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.

Book Description
In Soil Fertility Management in Agroecosystems, Editors Amitava Chatterjee and David Clay provide a thoughtful survey of important concepts in soil fertility management. For the requirements of our future workforce, it is imperative that we evolve our understanding of soil fertility. Agronomists and soil scientists are increasingly challenged by extreme climatic conditions. Farmers are experimenting with integrating cover crops into rotations and reducing the use of chemical fertilizers. In other words, there is no such a thing as a simple fertilizer recommendation in today's agriculture. Topics covered include crop-specific nutrient management, program assessment, crop models for decision making, optimization of fertilizer use, cover crops, reducing nitrous oxide emissions, natural abundance techniques, tile-drained conditions, and soil biological fertility.

Book Description
How can the United States meet demands for agricultural production while solving the broader range of environmental problems attributed to farming practices? National policymakers who try to answer this question confront difficult trade-offs. This book offers four specific strategies that can serve as the basis for a national policy to protect soil and water quality while maintaining U.S. agricultural productivity and competitiveness. Timely and comprehensive, the volume has important implications for the Clean Air Act and the 1995 farm bill. Advocating a systems approach, the committee recommends specific farm practices and new approaches to prevention of soil degradation and water pollution for environmental agencies. The volume details methods of evaluating soil management systems and offers a wealth of information on improved management of nitrogen, phosphorus, manure, pesticides, sediments, salt, and trace elements. Landscape analysis of nonpoint source pollution is also detailed. Drawing together research findings, survey results, and case examples, the volume will be of interest to federal, state, and local policymakers; state and local environmental and agricultural officials and other environmental and agricultural specialists; scientists involved in soil and water issues; researchers; and agricultural producers.

Book Description
The experiments and experiences discussed in Soil Management carefully document crop production systems with well-defined boundaries. These long-term agronomic trials provide a valuable data resource that has, until now, been largely ignored by both the research community and the sustainability experts. With a rigorous definition of sustainability and this data, the sustainability of various cropping systems will be more clearly illustrated than any previous effort. Particular emphasis is given to research involving the tropics and sub-tropics. This book is unique in providing an experimental basis for sustainable management of soil resources. It describes technological options for sustainable management of soil resources and identifies priorities for additional long-term experimentation needed in key ecoregions. Topics discussed include changes in soil processes and properties, environmental quality, soil management, soil dynamics, soil organic matter, and nutrient cycling. Soil Management is for those who ask whether agriculture is sustainable, want to analyze or review sustainability experiments and experiences, or wish to initiate new long-term trials. It is a valuable reference on soil processes and an excellent text for courses in soil management.

Book Description
Natural ecosystems provide the basic conditions without which humanity could not survive. Goods and services provided by ecosystems include, for example, provision of food, fibre and fuel, purification of water and air, cultural and aesthetic benefits, stabilization and moderation of the Earth's climate, generation and renewal of soil fertility, including nutrient cycling or maintenance of genetic resources as key inputs to crop varieties and livestock breeds, medicines, and other products. However, the ability of natural ecosystems to continue performing these services is seriously threatened because plant species diversity or soil are being seriously deteriorated, and in some cases destroyed. While loss of species has always occurred as a natural phenomenon, the pace of extinction has accelerated dramatically as a result of human activity. Ecosystems are being fragmented or eliminated, and innumerable species are in decline or already extinct. At the same time, various studies worldwide have shown that soils do not support intensive annual plant cultivation without fertilizer applications and even these may not maintain sustainability. Inappropriate silvicultural operations or the use of land for intensive agricultural purposes is one of the main causes of soil degradation, and there is therefore worldwide interest in quantifying the loss of soil quality generated by incorrect agricultural operations or forest management practises. This can only happen if people have the right information, skills, and organizations for understanding and dealing with soil and plant diversity issues. This books deals with soil management and restoration strategies in order to maintain soil quality avoiding soil deterioration. Throughout the book, different authors present very interesting works related to the nitrogen status of containerized Australian blackwood (Acacia Melanoxylon) seedings, soil carbon stocks in different vegetation types, biological soil crusts distribution in China sandy soils, ash soil fertilizers, the watershed management of badland areas, effects of pipeline construction-related disturbances on soil properties, soil quality indicators and soil hydrology in dry areas and aggregate characteristics within the soil active layer.
