Book Description
Elements move through Earth's critical zone along interconnected pathways that are strongly influenced by fluctuations in water and energy. The biogeochemical cycling of elements is inextricably linked to changes in climate and ecological disturbances, both natural and man-made. Biogeochemical Cycles: Ecological Drivers and Environmental Impact examines the influences and effects of biogeochemical elemental cycles in different ecosystems in the critical zone. Volume highlights include: Impact of global change on the biogeochemical functioning of diverse ecosystems Biological drivers of soil, rock, and mineral weathering Natural elemental sources for improving sustainability of ecosystems Links between natural ecosystems and managed agricultural systems Non-carbon elemental cycles affected by climate change Subsystems particularly vulnerable to global change The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Find out more about this book from this Q&A with the Author.

Book Description
Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.

Book Description
Crisscrossing Pleistocene terrace tops and overlooking the Gila River in southeastern Arizona are acres and acres of rock alignments that have perplexed archaeologists for a century. Well known but poorly understood, these features have long been considered agricultural, but exactly what was cultivated, how, and why remained a mystery. Now we know. Drawing on the talents of a team of scholars representing various disciplines, including geology, soil science, remote sensing, geographical information sciences (GISc), hydrology, botany, palynology, and archaeology, the editors of this volume explain when and why the grids were built. Between A.D. 750 and 1385, people gathered rocks from the tops of the terraces and rearranged them in grids of varying size and shape, averaging about 4 meters to 5 meters square. The grids captured rainfall and water accumulated under the rocks forming the grids. Agave was planted among the rocks, providing a dietary supplement to the maize and beans that were irrigated on the nearby bottom land, a survival crop when the staple crops failed, and possibly a trade commodity when yields were high. Stunning photographs by Adriel Heisey convey the vastness of the grids across the landscape.

Book Description
At Clay Bottom Farm, author Ben Hartman and staff practice kaizen, or continuous improvement, cutting out more waste--of time, labor, space, money, and more--every year and aligning their organic production more tightly with customer demand. Applied alongside other lean principles originally developed by the Japanese auto industry, the end result has been increased profits and less work. In this field-guide companion to his award-winning first book, The Lean Farm, Hartman shows market vegetable growers in even more detail how Clay Bottom Farm implements lean thinking in every area of their work, including using kanbans, or replacement signals, to maximize land use; germination chambers to reduce defect waste; and right-sized machinery to save money and labor and increase efficiency. From finding land and assessing infrastructure needs to selling perfect produce at the farmers market, The Lean Farm Guide to Growing Vegetables digs deeper into specific, tested methods for waste-free farming that not only help farmers become more successful but make the work more enjoyable. These methods include: Using Japanese paper pot transplanters Building your own germinating chambers Leaning up your greenhouse Making and applying simple composts Using lean techniques for pest and weed control Creating Heijunka, or load-leveling calendars for efficient planning Farming is not static, and improvement requires constant change. The Lean Farm Guide to Growing Vegetables offers strategies for farmers to stay flexible and profitable even in the face of changing weather and markets. Much more than a simple exercise in cost-cutting, lean farming is about growing better, not cheaper, food--the food your customers want.

Book Description
A celebrated biologist's manifesto addressing a soil loss crisis accelerated by poor conservation practices and climate change "Jo Handelsman is a national treasure, and her clarion call warning of a looming soil-loss catastrophe must be heard. Add her clearly written alarm to other future-shocks: climate change, pandemics, and mass extinctions."--Laurie Garrett, Pulitzer Prize winner and author of The Coming Plague: Newly Emerging Diseases in a World out of Balance "The ground beneath our feet is slipping away as we lose the precious soil that sustains us. Jo Handelsman's writing--as rich and life supporting as the soil itself--is a riveting warning."--Alan Alda, actor, writer, and host of the podcast Clear+Vivid with Alan Alda This book by celebrated biologist Jo Handelsman lays bare the complex connections among climate change, soil erosion, food and water security, and drug discovery. Humans depend on soil for 95 percent of global food production, yet let it erode at unsustainable rates. In the United States, China, and India, vast tracts of farmland will be barren of topsoil within this century. The combination of intensifying erosion caused by climate change and the increasing food needs of a growing world population is creating a desperate need for solutions to this crisis. Writing for a nonspecialist audience, Jo Handelsman celebrates the capacities of soil and explores the soil-related challenges of the near future. She begins by telling soil's origin story, explains how it erodes and the subsequent repercussions worldwide, and offers solutions. She considers lessons learned from indigenous people who have sustainably farmed the same land for thousands of years, practices developed for large-scale agriculture, and proposals using technology and policy initiatives.
