Dirt: The Ecstatic Skin of the Earth
Dirt: The Ecstatic Skin of the Earth by William Bryant Logan (W. W. Norton, 2007, $14.95) is a lovely way to get a good, easily digested dose of soil science surrounded by beautiful writing and musings. It is basically a natural history of the soil and the human connection with it. While not a new book, it's one worth re-reading again and again in order to remember where we came from, and to reinforce how good the earth is.
