Book Review: TEAMING WITH MICROBES—The Organic Gardener’s Guide to the Soil Food Web
By Jeff Lowenfels and Wayne Lewis

If you look closely at the title of this book, you will think there is a misspelling. But it is not by mistake that the authors use the word “teaming” rather
than “teeming.” The purpose of the book is to help gardeners understand the inhabitants and activities of the teeming microbes in the soil food web and to learn to team with these organisms to create the healthiest possible soil and plants in their gardens.

The soil is indeed teeming with microbes. The sheer number of each type is mind-blowing. “A mere teaspoon of good garden soil, as measured by microbial geneticists, contains a billion invisible bacteria, several yards of equally invisible fungal hyphae, several thousand protozoa, and a few dozen nematodes.” (p. 19) Bacteria are so small that a few hundred thousand can fit in a space the size of the period at the end of this sentence. The importance of these tiny soil microbes in supporting the health of plants cannot be underestimated. Yet many people (even some gardeners) have little understanding of the role and importance of these organisms and how to support their functioning.

The authors divide the book into two parts. The first part has a summary of soil science and a chapter devoted to each of the major participants in the soil food web: bacteria, archaea, fungi, algae and slime molds, protozoa, nematodes, arthropods, earthworms, gastropods, and larger animals. The role and functions of each group of organisms are described as well as their connection to gardening.

The second half of the book is devoted to explaining how to assess the health of the soil food web in your own soils and how to employ three major tools to build the health of that web: mulching, composting and making compost teas. The application of these tools for annuals and perennials is explained.

At the end of the book there is a gardening calendar and a summary of the authors’ 19 soil food web gardening rules. The information in this book is dense and concise and, as such, it is not an “easy” read. It resembles a textbook more than a gardening handbook. But it is worth wading all the way through to gain a better understanding of what should live in our soils, how these tiny organisms partner with and support our plants, and how not to interfere with their work and maybe even learn to support it.

Over time we are learning not to disrupt the soils in our gardens, yards and fields and instead help the food web to live and thrive in incredible balance, resulting in healthier plants and better crop yields. Teaming with Microbes is an important addition to the literature of no-till, restoration gardening and agriculture.
