N2  - "The extensive developments in crop research, improvement, and production methods in recent years justify a revised edition. More space is devoted to scientific principles and to the impact of cropping practices on the environment. Crop hybrids, cultivars, and pesticides are so numerous, so frequently changed, and so often merely of local interest that they are generally omitted. Many new books including symposium monographs that cover specific crops and cropping practices are now available. These are listed among the literature citations at the end of each chapter.
Much of the numerical data is expressed in metric figures, in accordance with the policy of the American Society of Agronomy. This will assist many foreign readers. The metric system may eventually be adopted in the United States."
