Beskrivning
This book provides scientifically based information on organic agriculture such as crop yields, food safety, nutrient use efficiency, leaching, long-term sustainability, greenhouse gas emissions and energy aspects.
From the reviews: "This book uses scientific literature to argue that organic agriculture as a model for sustainable farming is flawed. ... The authors make many valid points and present interesting arguments that definitely need to be addressed by organic proponents. ... The work as a whole would serve as a useful starting place for an in-depth, graduate-level discussion of the organic approach, research methods, and sustainability of agriculture in general. ... Summing Up: Recommended. ... Graduate students through professional audiences." (J. R. Reeve, Choice, Vol. 46 (11), July, 2009)
