Here’s a review on a new book on soil.

Soils had not excited many ecologists until, two decades ago, soil ecologists started emphasizing that many aboveground phenomena are under belowground control. Richard Bardgett is one of the most eloquent and knowledgeable of the soil scientists who have contributed to the current enthusiasm about soils. In his recent book Earth Matters: How Soil Underlies Civilization he explains how much human societies depend on soil. He writes about how soils are formed, how they influence biodiversity and food quality, and what role they play in cities and in war, and introduces us to the interplay of soils and climate change.
