ADDITIONAL READING

LECTURE 1:  Building Soils for Better Crops is a one-of-a-kind, practical guide to ecological soil management, now expanded and in full color. It provides step-by-step information on soil-improving practices as well as in-depth background—from what soil is to the importance of organic matter. Case studies of farmers from across the country provide inspiring examples of how soil—and whole farms—have been renewed through these techniques. A must-read for farmers, educators and students alike.

Written by University of Vermont plant and soil science professor emeritus Fred Magdoff and Cornell University soil science professor Harold van Es. Produced by Sustainable Agriculture Research and Education (SARE).

LECTURE 2:  The Alchemy of Air focuses on the importance of ammonium nitrate from wartime uses to feeding the World.  The book provides is a biography of the lives of Fritz Harber and Carl Bosch.  Details about how each was involved with the discovery of fixing atmospheric nitrogen to make synthetic nitrogen fertilizer will capture readers and make it difficult to book the book down.   See if you library has a copy to check out.

Those that enjoy listening to books and subscribe to www.audible.com can listen to the contents, the way I enjoyed the book.   (Note:  A paperback copy of this book has been donated each participating school.)

LECTURE 3:  Loss of nitrogen (N) as ammonia gas (NH3) is known as volatilization. While volatilization directly from soil can occur, such loss is generally relatively small compared to the amount that can be lost from fertilizers. Volatilization losses can be significant with granular urea and urea-ammonium nitrate (UAN) sources, but the amount of loss varies greatly depending on placement of the fertilizer, soil pH, soil texture, and climatic conditions after application.

This publication will discuss a number of factors that influence the occurrence and/or rate of ammonia volatilization.
