The Encyclopedia of Soil Science provides a comprehensive, alphabetical treatment of basic soil science in a single volume. It constitutes a wide ranging and authorative collection of some 160 academic articles covering the salient aspects of soil physics, chemistry, biology, fertility, technology, genesis, morphology, classification and geomorphology. With increased usage of soil for world food production, building materials, and waste repositories, demand has grown for a better global understanding of soil and its processes. longer articles by leading authorities from around the world are supplemented by some 430 definitions of common terms in soil sciences.

"Set aside your Bella Tuscanys and Year in Provences for a different kind of travel book. Pilgrimage to Vallombrosa puts a walking stick in your hand and Marsh’s Man and Nature in your knapsack, exploring how Italians have managed their natural and cultural heritage in ways that sustain both. John Elder’s poetic meditations on land and life demonstrate that only by searching beyond our familiar boundaries can we discover better ways of living back at home."—Marcus Hall, author of Earth Repair: A Transatlantic History of Environmental Restoration "This collaboration—between George Perkins Marsh and John Elder, between Vermont and Italy, between maple and olive—is one of the smartest, soundest, deepest books about the relationship between people and nature that I’ve ever read. It will be a classic."—Bill McKibben, author of The End of Nature "Elder’s impassioned pilgrimage shows us how to delight in messy wilderness, to secure a curative habitation of the world, and, with Marsh, to lend ecological nous to our gravest task: knowing ourselves and respecting one another. Let the maple seeds and olive stones of Elder’s visionary harvest restore to us a reflective and redemptory future."—from the foreword by David Lowenthal The pivotal figure in Pilgrimage to Vallombrosa is the nineteenth-century diplomat and writer George Perkins Marsh, generally regarded as America’s first environmentalist. Like Elder, Marsh was a Vermonter, and his diplomatic career took him for some years to Italy, where, witnessing the ecological devastation wrought upon the landscape by runaway deforestation and the plundering of other natural resources, he was moved to produce his famous manifesto, Man and Nature. Marsh drew parallels between the despoiled Italian environment and his home landscape of Vermont, warning that the latter was vulnerable to ecological woes of a similar magnitude if not carefully maintained and protected. In short, his was a prescient voice for stewardship. Elder follows in Marsh’s footsteps along a trajectory running from Vermont to Italy, and at length fetches up at the managed forest of Vallombrosa. Punctuated throughout with learned and genial considerations of the poetry of Wordsworth, Basho, Dante, and Frost, Elder’s narrative takes up issues of sustainability as practiced locally, reports on family doings, and returns finally—as did Marsh’s—to Vermont, where he measures traditional stewardship values against more aggressive conservation-oriented measures such as the expansion of wilderness areas. John Elder, Professor of English and Environmental Studies at Middlebury College, is the author of Reading the Mountains of Home and The Frog Run.
