This book presents a novel and systematic social theory of soil, and is representative of the rising interest in 'the material' in social sciences. Bringing together new modes of 'critical description' with speculative practices and methods of inquiry, it contributes to the exploration of current transformations in socioecologies, as well as in political and artistic practices, in order to address global ecological change. The chapters in this edited volume challenge scholars to attend more carefully to the ways in which they think about soil, both materially and theoretically. Contributors address a range of topics, including new ways of thinking about the politics of caring for soils; the ecological and symbiotic relations between soils; how the productive capacities and contested governance of soils are deployed as matters of political concern; and indigenous ways of knowing and being with soil.

The papers assembled here cover topics such as technological advances in soil salinity mapping and monitoring, management and reclamation of salt-affected soils, use of marginal quality water for crop production, salt-tolerance mechanisms in plants, biosaline agriculture and agroforestry, microbiological interventions for marginal soils, opportunities and challenges in using marginal waters, and soil and water management in irrigated agriculture.

Soil! We walk on it, play in it, build with it, grow our food in it, and get antibiotics from it. But what exactly is soil? What makes it so important? Can we survive without it? In Explore Soil! With 25 Great Projects, young readers learn how vital soil is to our lives. It filters the water we drink and the air we breathe, and most of the food we eat either grows in soil or subsists on plants that grow there. Soil is a very important part of our daily diet! Activities such as exploring soil runoff, composting, and analyzing soil composition offer kids the chance to get their hands dirty while coming face to face with the study of soil. Kids learn concepts within the fields of life science and chemistry while discovering the dangers soil faces. Explore Soil offers fun, practical information about something kids already love: soil!

Dirt, soil, call it what you want—it's everywhere we go. It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.

Thousands of years of poor farming and ranching practices—and, especially, modern industrial agriculture—have led to the loss of up to 80 percent of carbon from the world’s soils. That carbon is now floating in the atmosphere, and even if we stopped using fossil fuels today, it would continue warming the planet. In The Soil Will Save Us, journalist and bestselling author Kristin Ohlson makes an elegantly argued, passionate case for "our great green hope"—a way in which we can not only heal the land but also turn atmospheric carbon into beneficial soil carbon—and potentially reverse global warming. As the granddaughter of farmers and the daughter of avid gardeners, Ohlson has long had an appreciation for the soil. A chance conversation with a local chef led her to the crossroads of science, farming, food, and environmentalism and the discovery of the only significant way to remove carbon dioxide from the air—an ecological approach that tends not only to plants and animals but also to the vast population of underground microorganisms that fix carbon in the soil. Ohlson introduces the visionaries—scientists, farmers, ranchers, and landscapers—who are figuring out in the lab and on the ground how to build healthy soil, which solves myriad problems: drought, erosion, air and water pollution, and food quality, as well as climate change. Her discoveries and vivid storytelling will revolutionize the way we think about our food, our landscapes, our plants, and our relationship to Earth.

Emphasizing pioneering achievements, this work offers a clear and systematic description of various soil-water phenomena and their applications to soil problems such as water retention and the flux of water in soils and clays. This second edition contains material on the physical properties of adsorbed water, the application of fractal theory to solute and water flows in field soils, fingering research, and more.

In Colombia, decades of social and armed conflict and the US-led war on drugs have created a seemingly untenable situation for scientists and rural communities as they attempt to care for forests and grow non-illicit crops. In Vital Decomposition Kristina M. Lyons presents an ethnography of human-soil relations. She follows state soil scientists and peasants across labs, greenhouses, forests, and farms and attends to the struggles and collaborations between farmers, agrarian movements, state officials, and scientists over the meanings of peace, productivity, rural development, and sustainability in Colombia. In particular, Lyons examines the practices and philosophies of rural farmers who value the decomposing layers of leaves, which make the soils that sustain life in the Amazon, and shows how the study and stewardship of the soil point to alternative frameworks for living and dying. In outlining the life-making processes that compose and decompose into soil, Lyons theorizes how life can thrive in the face of the violence, criminalization, and poisoning produced by militarized, growth-oriented development.

Recounts the author's experiences founding a faith-based community garden in rural North Carolina, and emphasizes how growing one's own food can help readers reconnect with the land and divine faith.
