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.

Ranging from ancient times to modern-day environmental threats, a natural and cultural history of soil explains how an elimination of protective vegetation and an exposure to wind and rain causes severe erosion of cultivated soils, how the use and abuse of soil has shaped human history, and the how the rise of organic and no-till farming holds hope for the future.

A MacArthur Fellow’s impassioned call to make agriculture sustainable by ditching the plow, covering the soil, and diversifying crop rotations. The problem of agriculture is as old as civilization. Throughout history, great societies that abused their land withered into poverty or disappeared entirely. Now we risk repeating this ancient story on a global scale due to ongoing soil degradation, a changing climate, and a rising population. But there is reason for hope. David R. Montgomery introduces us to farmers around the world at the heart of a brewing soil health revolution that could bring humanity’s ailing soil back to life remarkably fast. Growing a Revolution draws on visits to farms in the industrialized world and developing world to show that a new combination of farming practices can deliver innovative, cost-effective solutions to problems farmers face today. Cutting through standard debates about conventional and organic farming, Montgomery explores why practices based on the principles of conservation agriculture help restore soil health and fertility. Farmers he visited found it both possible and profitable to stop plowing up the soil and blanketing fields with chemicals. Montgomery finds that the combination of no-till planting, cover crops, and diverse crop rotations provides the essential recipe to rebuild soil organic matter. Farmers using these unconventional practices cultivate beneficial soil life, smother weeds, and suppress pests while relying on far less, if any, fertilizer and pesticides. These practices are good for farmers and the environment. Using less fossil fuel and agrochemicals while maintaining crop yields helps farmers with their bottom line. Regenerative practices also translate into farms that use less water, generate less pollution, lower carbon emissions—and stash an impressive amount of carbon underground. Combining ancient wisdom with modern science, Growing a Revolution lays out a solid case for an inspiring vision where agriculture becomes the solution to environmental problems, helping feed us all, cool the planet, and restore life to the land.

A riveting exploration of how microbes are transforming the way we see nature and ourselves—and could revolutionize agriculture and medicine. Prepare to set aside what you think you know about yourself and microbes. Good health—for people and for plants—depends on Earth’s smallest creatures. The Hidden Half of Nature tells the story of our tangled relationship with microbes and their potential to revolutionize agriculture and medicine, from garden to gut. When David R. Montgomery and Anne Biklé decide to restore life into their barren yard by creating a garden, dead dirt threatens their dream. As a cure, they feed their soil a steady diet of organic matter. The results impress them. In short order, the much-maligned microbes transform their bleak yard into a flourishing Eden. Beneath their feet, beneficial microbes and plant roots continuously exchange a vast array of essential compounds. The authors soon learn that this miniaturized commerce is central to botanical life’s master strategy for defense and health. They are abruptly plunged further into investigating microbes when Biklé is diagnosed with cancer. Here, they discover an unsettling truth. An armada of bacteria (our microbiome) sails the seas of our gut, enabling our immune system to sort microbial friends from foes. But when our gut microbiome goes awry, our health can go with it. The authors also discover startling insights into the similarities between plant roots and the human gut. We are not what we eat. We are all—for better or worse—the product of what our microbes eat. This leads to a radical reconceptualization of our relationship to the natural world: by cultivating beneficial microbes, we can rebuild soil fertility and help turn back the modern plague of chronic diseases. The Hidden Half of Nature reveals how to transform agriculture and medicine—by merging the mind of an ecologist with the care of a gardener and the skill of a doctor.

Gabe Brown didn't set out to change the world when he first started working alongside his father-in-law on the family farm in North Dakota. But as a series of weather-related crop disasters put Brown and his wife, Shelly, in desperate financial straits, they started making bold changes to their farm. Brown--in an effort to simply survive--began experimenting with new practices he'd learned about from reading and talking with innovative researchers and ranchers. As he and his family struggled to keep the farm viable, they found themselves on an amazing journey into a new type of farming: regenerative agriculture. Brown dropped the use of most of the herbicides, insecticides, and synthetic fertilizers that are a standard part of conventional agriculture. He switched to no-till planting, started planting diverse cover crops mixes, and changed his grazing practices. In so doing Brown transformed a degraded farm ecosystem into one full of life--starting with the soil and working his way up, one plant and one animal at a time. In Dirt to Soil Gabe Brown tells the story of that amazing journey and offers a wealth of innovative solutions to our most pressing and complex contemporary agricultural challenge--restoring the soil. The Brown's Ranch model, developed over twenty years of experimentation and refinement, focuses on regenerating resources by continuously enhancing the living biology in the soil. Using regenerative agricultural principles, Brown's Ranch has grown several inches of new topsoil in only twenty years! The 5,000-acre ranch profitably produces a wide variety of cash crops and cover crops as well as grass-finished beef and lamb, pastured laying hens, broilers, and pastured pork, all marketed directly to consumers. The key is how we think, Brown says. In the industrial agricultural model, all thoughts are focused on killing things. But that mindset was also killing diversity, soil, and profit, Brown realized. Now he channels his creative thinking toward how he can get more life on the land--more plants, animals, and beneficial insects. "The greatest roadblock to solving a problem," Brown says, "is the human mind."
