Book Description
Despite the connections between soils and human health, there has not been a great amount of attention focused on this area when compared to many other fields of scientific and medical study. Soils and Human Health brings together authors from diverse fields with an interest in soils and human health, including soil science, geology, geography, biology, and anthropology to investigate this issue from a number of perspectives. The book includes a soil science primer chapter for readers from other fields, and discusses the ways the soil science community can contribute to improving our understanding of soils and human health. Features Discusses ways the soil science community can contribute to the improvement of soil health Approaches human health from a soils-focused perspective, covering the influence of soil conservation and contact with soil on human health Illustrates topics via case studies including arsenic in groundwater in Bangladesh; the use of Agent Orange in Vietnam; heavy metal contamination in Shipham, United Kingdom and Omaha, Nebraska, USA; and electronic waste recycling in China. In a scientific world where the trend has often been ever-increasing specialization and increasingly difficult communication between fields and subfields, the interdisciplinary nature of soils and human health studies presents a significant challenge going forward. Fields with an interest in soils and human health need to have increased cross-disciplinary communication and cooperation. This book is a step in the direction of accessibility and innovation, elucidating the state of knowledge in the meeting of soil and health sciences, and identifying places where more work is needed.

Book Description
Protists are by far the most diverse and abundant eukaryotes in soils. Nevertheless, very little is known about individual representatives, the diversity and community composition and ecological functioning of these important organisms. For instance, soil protists are commonly lumped into a single functional unit, i.e. bacterivores. This work tackles missing knowledge gaps on soil protists and common misconceptions using multi-methodological approaches including cultivation, microcosm experiments and environmental sequencing. In a first part, several new species and genera of amoeboid protists are described showing their immense unknown diversity. In the second part, the enormous complexity of soil protists communities is highlighted using cultivation- and sequence-based approaches. In the third part, the present of diverse mycophagous and nematophagous protists are shown in functional studies on cultivated taxa and their environmental importance supported by sequence-based approaches. This work is just a start for a promising future of soil Protistology that is likely to find other important roles of these diverse organisms.

Book Description
“A breakthrough book. No comprehensive horticultural library should be without it.” —American Gardener When we use chemical fertilizers, we injure the microbial life that sustains plants, and then become increasingly dependent on an arsenal of toxic substances. Teaming with Microbes offers an alternative to this vicious circle, and details how to garden in a way that strengthens, rather than destroys, the soil food web. You’ll discover that healthy soil is teeming with life—not just earthworms and insects, but a staggering multitude of bacteria, fungi, and other microorganisms. This must-have guide is for everyone, from those devoted to organic gardening techniques to weekend gardeners who simply want to grow healthy plants without resorting to chemicals.

Book Description
Principles and farm-tested practices for no-till market gardening--for healthier, more productive soil! From the host of the popular The No-Till Market Garden Podcast—heard around the world with nearly one million downloads! Discovering how to meet the soil’s needs is the key task for every market gardener. In this comprehensive guide, Farmer Jesse Frost shares all he has learned through experience and experimentation with no-till practices on his home farm in Kentucky and from interviews and visits with highly successful market gardeners in his role as host of The No-Till Market Garden Podcast. The Living Soil Handbook is centered around the three basic principles of no-till market gardening: Disturb the soil as little as possible Keep it covered as much as possible Keep it planted as much as possible. Farmer Jesse then guides readers in applying those principles to their own garden environment, with their own materials, to meet their own goals. Beginning with an exploration of the importance of photosynthesis to living soil, Jesse provides in-depth information on: Turning over beds Using compost and mulch Path management Incorporating biology, maintaining fertility Cover cropping Diversifying plantings through intercropping Production methods for seven major crops Throughout, the book emphasizes practical information on all the best tools and practices for growers who want to build their livelihood around maximizing the health of their soil. Farmer Jesse reminds growers that “as possible” is the mantra for protecting the living soil: disturb the soil as little as you possibly can in your context. He does not believe that growers should anguish over what does and does not qualify as “no-till.” If you are using a tool to promote soil life and biology, that’s the goal. Jesse’s goal with The Living Soil Handbook is to provide a comprehensive set of options, materials, and field-tested practices to inspire growers to design a soil-nurturing no-till system in their unique garden or farm ecosystem. "[A] practical, informative debut. . . .Gardeners interested in sustainable agriculture will find this a great place to start."—Publishers Weekly "Frost offers a comprehensive, science-based, sympathetic, wholly practical guide to soil building, that most critical factor in vegetable gardening for market growers and home gardeners alike. A gift to any vegetable plot that will keep on giving."—Booklist (starred review)

Book Description
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.
