Soil is the basis not only for all gardening, but for all terrestrial life. No aspect of agriculture is more fundamental and important, yet we have been losing vast quantities of our finite soil resources to erosion, pollution, and development.

Now back in print, this eminently sensible and wonderfully well-focused book provides essential information about one of the most significant challenges for those attempting to grow delicious organic vegetables: the creation and maintenance of healthy soil.

Chapter 2, “Understanding the Soil System,” is alone worth the price of admission. Gershuny and Smillie give lay readers and experts a clear explanation of subjects–soil life and nutrient cycles–that have confounded most authors. Nowhere will the reader find simpler and more coherent descriptions of key concepts including cation exchange capacity and chelation.

There are other books about soil available, including Grace Gershuny’s comprehensive Start with the Soil, and there are books that feature chapters on soil building. What distinguishes The Soil of Soilis the authors’ concise presentation; they give readers important information, including technical essentials, without getting bogged down in scientific or quasiscientific mumbo-jumbo. In addition, useful tables list specific compost materials, green manures, and other resources that allow growers to translate into action the more general information provided by the book.

The soil-building techniques featured include:

• Organic matter management
• Building and maintaining humus
• On-site composting
• Green manures and rotations
• Cultivation and weed control
• Nutrient balances and soil testing
• Using mineral fertilizers
• Planning for organic certification
