Raymond Bial

A Handful of Dirt, by Raymond Bial. 32 pages. Publisher: Walker Books for Young Readers (May 15, 2000) Reading level: Ages 9-12. Soil may not be alive, but amazingly, multitudes of microscopic creatures live there, battling it out in an eat-or-be-eaten world. These tiny creatures, invisible to our eyes, provide food for the insects that in turn feed the reptiles and mammals that live in and above the soil. You'll never look at the ground you walk on in the same way after Raymond Bial, an award-winning photo essayist, takes you on this eye-opening, down-and-dirty tour of one of the earth's most precious resources.

Teaming with Microbes: The Organic Gardener's Guide to the Soil Food Web
Teaming with Microbes

Teaming with Microbes: The Organic Gardener's Guide to the Soil Food Web, by Jeff Lowenfels and Wayne Lewis. 220 pages. Publisher: Timber Press; Revised edition (February 24, 2010) Smart gardeners know that soil is anything but an inert substance. Healthy soil is teeming with life — not just earthworms and insects, but a staggering multitude of bacteria, fungi, and other microorganisms. When we use chemical fertilizers, we injure the microbial life that sustains healthy plants and become increasingly dependent on an arsenal of artificial, often toxic, substances. But there is an alternative to this vicious cycle. We can garden in a way that strengthens the soil food web — the complex world of soil-dwelling organisms whose interactions create a nurturing environment for plants.

Life in the Soil: A Guide for Naturalists and Gardeners
Life in the Soil
James B. Nardi

Life in the Soil: A Guide for Naturalists and Gardeners, by James B. Nardi. 336 pages. Publisher: University Of Chicago Press (October 15, 2007) Leonardo da Vinci once mused that “we know more about the movement of celestial bodies than about the soil underfoot,” an observation that is as apt today as it was five hundred years ago. The biological world under our toes is often unexplored and unappreciated, yet it teems with life. In one square meter of earth, there lives trillions of bacteria, millions of nematodes, hundreds of thousands of mites, thousands of insects and worms, and hundreds of snails and slugs. But because of their location and size, many of these creatures are as unfamiliar and bizarre to us as anything found at the bottom of the ocean.

Lavishly illustrated with nearly three hundred color illustrations and masterfully-rendered black and white drawings throughout, Life in the Soil invites naturalists and gardeners alike to dig in and discover the diverse community of creatures living in the dirt below us.
