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.
