Discussing the science, technology, and philosophy of organic agriculture, this book addresses relevant issues and concepts along with practical applications. Chapters cover soil fertility and plant nutrition; individual plant requirements; liming; farm manures, green manures, and composts; mulching and tillage; and weed, insect, and disease control, as well as companion planting and storage. Accessible to undergraduate students in organic farming and gardening, and sustainable agriculture, the text includes a glossary with common technical and scientific terms used in conventional and organic agriculture and provides an accompanying CD-ROM with full-colour illustrations and additional ancillary material for students.

This impressive book untangles the complicated and sometimes confusing subject of organic farming. Barker deftly and succinctly not only addresses practical tasks in the field, but also explains both the historical and philosophical theory that has built modern organic practices. ! Chapters devoted to individual soil nutrients are not a repetition of those in other soil science books; instead, the author relates nutrient availability to organic practices. Perhaps the most valuable chapters present informed practices of composting, green manure management, companion planting, proper liming, and the correct use of mulches! . The chapters on pest control, with specific tools for managing particular pests including insects and diseases, exhibit the author's extensive knowledge of organic practices. ! Barker uses scientific thought to support his methods, rare in many of today's trendy treatises, and debunks the nonscientific methods associated with organic practices that diminish the science's logic and legitimacy. Summing Up: Highly recommended. --CHOICE, January 2011 ! Professor Barker draws upon his more than 45 years of experience and expertise to first identify the history and define the practices that comprise organic farming. ! an essential, core addition to personal, professional, academic, and community library reference collections. Also very highly recommended from CRC Press for anyone seeking to convert from industrial agriculture to organic farming is Stephen R. Gliessman and Martha Rosemeyer's The Conversion to Sustainable Agriculture: Principles, Processes, and Practices. --James A. Cox, Editor-in-Chief, Midwest Book Review, August 2010 Plant nutrition covers 'organic' fertilizers, defined as those derived from biological or mineral materials. This section is a comprehensive summary of the functions of 14 essential elements, including crop requirements and deficiency symptoms. ... the book presents a basic introduction to crop science that is clearly relevant and provides some useful specific insights into crop nutrition. --Susanne Padel, The Journal of Experimental Agriculture, 47(1), 2011
