Nitrogen constitutes about 79 percent of the earth's atmosphere, yet, in an agricultural plant production system, it is still common for soils to be deficient of the nitrogen needed for maximum plant growth. But nitrogen fertilizers that are essential for the economically driven production of food and fiber are recognized as polluters of natural waters, and it has become increasingly apparent that manufactured and naturally occurring nitrogen resources must be better managed. This book addresses the problem by describing how the various factors such as types of soils and crops, irrigation methods, climate, and the nitrogen cycle itself affect levels of nitrogen in plant production systems. The book also provides a practical guide to the many advantages and disadvantages of using different fertilizers across such factors as environment, type of plant, and method of farming. This book will be part of the solution to nitrogen management and agricultural problems and will be of interest to workers in local, state, and federal agricultural extension services, consulting firms, environmental regulators, and students and researchers in soil chemistry.

"The authors present a very readable review of the factors involved in nitrogen management. In a final summary chapter, the authors reemphasize a point that runs throughout: all the factors presented are interrelated. They urge careful consideration of conditions in an individual agricultural system to achieve responsible nitrogen management." --Choice"Geochemists, especially those not well versed in farming practice, would be well advised to peruse this interesting book. Though focused on U.S. agriculture, the book deals with general agricultural chemical principles and practice, and thus helps the reader to understand the basis for traditional or scientific farming in any part of the world....I took the trouble to read this book carefully, have learned much from it, and like it....Urbanization is deprivingmany of us of a practical understanding of how crops are grown and how agriculture is changing as a result of new technologies and in response to newly recognized environmental constraints, Professors Rauschkolb and Hornsby...make it possible for geochemists and others to make up for this deficiencyin their education if they will take time to read this book, which I recommend they do." --Geochimica et Cosmochimica Acta"The book provides a useful general review . . . and should be of value to agricultural researchers and students."--The Quarterly Review of Biology
