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.

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.

Taking a broad and innovative informational approach, Sustainable Agriculture and New Biotechnologies is the first book to apply omic technologies to address issues related to understanding and improving agricultural sustainability in the food production process. The transformation from industrial to sustainable agriculture is discussed within the frameworks of new biotechnologies and global environmental changes. While considering this transformation, the book covers: The use of new biotechnologies to help in the creation of more sustainable agricultural practices, including methods in molecular biology, genetic engineering, and the new emerging technologies, such as metabolomics, metagenomics, nutrigenomics, and ionomics The path to reach the goal of the global sustainable agricultural and food production systems in a world of limited natural resources and growing environmental degradation Principles that regulate the new agricultural and food production systems including breeding programs for more sustainable crops, soil management, and environment preservation It is clear that biotechnological approaches will become increasingly important in the future and that a shift from industrial to a sustainable agriculture will be necessary. While many books tend to make "a quick and easy link" between these two different worlds, Sustainable Agriculture and New Biotechnologies describes exactly how omics can contribute to greater food productivity and security, and agricultural sustainability in the future.

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.

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.

Emphasizes Centrality of the Ecosystem Perspective Sustainable management of agroecosystems in the 21st century faces unprecedented challenges. Protecting the environment while feeding a burgeoning population that could reach nine billion by mid-century, preserving the world’s biodiversity, and sustaining agriculture in an increasingly urban world is a massive undertaking. Avoiding simple prescriptions for the application of ecological principles to agriculture, Sustainable Agroecosystem Management: Integrating Ecology, Economics, and Society emphasizes the continued centrality of the ecosystem perspective, and the need to integrate ecological, economic, and social considerations in agroecosystem science and management. Truly Interdisciplinary in Scope With contributions from distinguished leaders in the field of sustainable agriculture, this authoritative book first delineates the present and future challenges agroecosystems face. It then reviews the important contributions made by Dr. Ben Stinner, a pioneer in the field of agroecosystem ecology. Providing historical background of attempts to connect the ecological and agricultural sciences, this standard-setting resource highlights recent efforts to integrate natural and social science perspectives. It also examines the challenges for developing integrated approaches to agroecosystem management. Through a variety of case studies with global applications, the text makes it abundantly clear that purely technological approaches are insufficient for solving the food systems problems of the future. It explores practical innovative strategies, policies, and research needs necessary to develop management approaches that emphasize whole system productivity, diversify agricultural operations, and sustain multiple functions, including ecological integrity.
