Here is a book that gets right to the bottom of things. A rambling study of the function and physiology of root systems, their history and future, the book deals with the chemical, biological, and epicurean aspects of root lore. Unfortunately, it covers too much ground turning from the dimensions of root ecology to highlights in the lives of early grass-root excavators. Though the author is no word wizard, he does convince us that ""root power,"" if not quite miraculous, certainly is useful. And for Wilson, who has made a career of books on plant life (Bodacious Ozarks and Grass and People), roots definitely are no dead end.
