Recognition of the importance of soil organic matter (SOM) in soil health and quality is a major part of fostering a holistic, preventive approach to agricultural management. Students in agronomy, horticulture, and soil science need a textbook that emphasizes strategies for using SOM management in the prevention of chemical, biological, and physical problems. Soil Organic Matter in Sustainable Agriculture gathers key scientific reviews concerning issues that are critical for successful SOM management. This textbook contains evaluations of the types of organic soil constituents—organisms, fresh residues, and well-decomposed substances. It explores the beneficial effects of organic matter on soil and the various practices that enhance SOM. Chapters include an examination of the results of crop management practices on soil organisms, organic matter gains and losses, the significance of various SOM fractions, and the contributions of fungi and earthworms to soil quality and crop growth. Emphasizing the prevention of imbalances that lead to soil and crop problems, the text also explores the development of soils suppressive to plant diseases and pests, and relates SOM management to the supply of nutrients to crops. This book provides the essential scientific background and poses the challenging questions that students need to better understand SOM and develop improved soil and crop management systems.

By better understanding the complex codependent relationships between soils, soil organisms, and crops, scientists can better predict how an agricultural system will behave when the use of tillage, pesticides, and fertilizers is reduced. Soil Ecology in Sustainable Agricultural Systems demonstrates the considerable potential for the application of soil biological knowledge to the sound management of agroecosystems. Chapters 1-6 cover basic studies, with some focusing on the dual nature of roots and soil organic matter as sinks and sources of carbon and nutrients. Other studies focus on the effects of structure-following and structure-forming soil organisms on biochemical and biophysical processes. Chapter 7 takes a more holistic approach and ties basic knowledge together at the agroecosystem level and discusses developing biological management practices that optimize soil properties for sustained agricultural use. In Soil Ecology in Sustainable Agricultural Systems, agronomists will find new research and applications for using the tools of ecology to understand the workings of an agricultural system, and environmentalists and ecologists will gain a better understanding of ecosystems that are created by both man and nature.

Providing the theoretical and conceptual framework for this continually evolving field, Agroecology: The Ecology of Sustainable Food Systems, Second Edition explores environmental factors and complexities affecting agricultural crops and animals. Completely revised, updated, and reworked, the second edition contains new data, new readings, new issues and case studies, and new options. It includes two completely new chapters, one on the role of livestock animals in agroecosystems and one on the cultural and community aspects of sustainable food systems. The author clearly delineates the importance of using an ecosystem framework for determining if a particular agricultural practice, input, or management decision contributes or detracts from sustainability. He explains how the framework provides the ecological basis for the functioning of the chosen management strategy over the long-term. He also examines system level interactions, stressing the need for understanding the emergent qualities of populations, communities, and ecosystems and their roles in sustainable agriculture. Using examples of farming systems in a broad array of ecological conditions, the book demonstrates how to use an ecosystem approach to design and manage agroecosystems for sustainability.

Sustainable agriculture is a key concept for scientists, researchers, and agricultural engineers alike. This book focuses on the FAM- project (FAM Munich Research Network on Agroecosystems) of the 1990s as a means to assessing, forecasting, and evaluating changes in the agroecosystems that are necessary for agricultural sustainability. The management of two separate management systems: an organic and an integrated farming system are described to provide an interdisciplinary approach Changes of matter fluxes in soils, changes of trace gas fluxes from soils, precision farming in a small scale heterogen landscape, influence of management changes on flora and fauna, as well as the development of agroecosystem models, the assessment of soil variability and the changes in nutrient status are important aspects of this book. * Contains detailed results and insight of a long-time project on agricultural sustainability * Provides an interdisciplinary approach for comprehensive understanding by scientists and researchers of soil, plants, agriculture, and environment * Includes an international perspective

We hear a lot about how agriculture affects climate change and other environmental issues, but we hear little about how these issues affect agriculture. When we look at both sides of the issues, we can develop better solutions for sustainable agriculture without adversely affecting the environment. Agroecology, Ecosystems, and Sustainability explores a modern vision of ecology and agricultural systems, so that crop production can be sustainably developed without further environmental degradation. With contributions from experts from more than 20 countries, the book describes how to make the transition to modern agroecology to help the environment. It examines the global availability of natural resources and how agroecology could allow the world population to reach the goal of global sustainable ecological, agricultural, and food production systems. The book discusses important principles that regulate agroecological systems, including crop production, soil management, and environment preservation. Making the link between theory and practices, the book includes examples of agroecology such as an interdisciplinary framework for the management of integrated production and conservation landscapes and the use of mechanized rain-fed farming and its ecological impact on drylands. An examination of how ecology and agriculture can be allied to ensure food production and security without threatening our environment, the text shows you how natural resources can be used in a manner to create a "symbiosis" to preserve ecological systems and develop agriculture.

While organic soils have the potential to contribute greatly to agricultural production, the irreversible processes that occur from draining organic soils need to be managed with caution. The wise use of peatlands must include the avoidance of unacceptable ecological effects on the contiguous and global environment. Organic Soils and Peat Materials for Sustainable Agriculture provides detailed information from a worldwide perspective on the degradation process of fragile peat resources used for agriculture. It documents the best management practices and defines and quantifies soil quality indicators and pedo-transfer functions for organic soils and peat materials. Co-published with the International Peat Society, this reference is the first to integrate the physical, chemical, and biological aspects of organic soils and peat materials for sustainable agriculture and horticulture. It details the principles and indicators behind positive action in sustainable management. The book presents a complete analysis of how peat works chemically, physically, and ecologically. It quantifies the moorsh-forming, or peat degradation, process in tables and figures, provides conversion equations among pH determination methods, and supplies a novel diagnosis of N and P release. In addition, the book revisits water, pesticides, phosphorus, and copper sorption characteristics of organic soils. The authors provide up-to-date information in order to define quality indicators for the optimum use of organic soils. With detailed information and a global perspective, Organic Soils and Peat Materials for Sustainable Agriculture aims to promote a shift from the current paradigm of input-based unsustainable use to a new knowledge-based approach.

With all of the environmental and social problems confronting our food systems today, it is apparent that none of the strategies we have relied on in the past―higher-yielding varieties, increased irrigation, inorganic fertilizers, pest damage reduction―can be counted on to come to the rescue. In fact, these solutions are now part of the problem. It is becoming quite clear that the only way to keep the food crisis from escalating is to promote the conversion processes that will move agriculture to sustainability. Under the editorial guidance of agroecology experts Martha Rosemeyer and the internationally renowned Dr. Stephen R. Gliessman, The Conversion to Sustainable Agriculture: Principles, Processes, and Practices establishes a framework for how this conversion can be accomplished and presents case studies from around the world that illustrate how the process is already underway. The book provides a four-stage transition process for achieving sustainability and an in-depth analysis of the global efforts to make farms more energy-efficient and environmentally friendly. An international team of chapter contributors explores ways to lessen dependency on fossil fuels and pesticides, and examines each step in the conversion process. They also describe the process of monitoring change toward sustainable agriculture while integrating social and economic analysis within scientific practices. Serving as both a core textbook for students and a comprehensive reference for agricultural practitioners, this volume is a valuable resource for the change that is needed in our food system now and in the future.
