'The new edition of Crop Ecology, by Connor, Loomis, and Cassman, retains the strengths of the earlier edition, namely, insightful analysis of the key principles that explain crop resource use and growth, based on extensive use of peer-reviewed data, averaging more than one graph or table per page. Any practitioner or student of 'evidence-based agriculture' needs a copy of this book.' R. Ford Denison, University of Minnesota, and author of Darwinian Agriculture
