Soil and Fertilizers: Managing the Environmental Footprint presents strategies to improve soil health by reducing the rate of fertilizer input while maintaining high agronomic yields. It is estimated that fertilizer use supported nearly half of global births in 2008. In a context of potential food insecurity exacerbated by population growth and climate change, the importance of fertilizers in sustaining the agronomic production is clear. However, excessive use of chemical fertilizers poses serious risks both to the environment and to human health. Highlighting a tenfold increase in global fertilizer consumption between 2002 and 2016, the book explains the effects on the quality of soil, water, air and biota from overuse of chemical fertilizers. Written by an interdisciplinary author team, this book presents methods for enhancing the efficiency of fertilizer use and outlines agricultural practices that can reduce the environmental footprint. Features: Includes a thorough literature review on the agronomic and environmental impact of fertilizer, from degradation of ecosystems to the eutrophication of drinking water Devotes specific chapters to enhancing the use efficiency and effectiveness of the fertilizers through improved formulations, time and mode of application, and the use of precision farming technology Reveals geographic variation in fertilizer consumption volume by presenting case studies for specific countries and regions, including India and Africa Discusses the pros and cons of organic vs. chemical fertilizers, innovative technologies including nuclear energy, and the U.N.’s Sustainable Development Goals Part of the Advances in Soil Sciences series, this solutions-focused volume will appeal to soil scientists, environmental scientists and agricultural engineers.
The majority of meat, milk, and eggs consumed in the United States are produced in concentrated animal feeding operations (CAFO). With concentrated animal operations, in turn comes concentrated manure accumulation, which can pose a threat of contamination of air, soil, and water if improperly managed. Animal Manure: Production, Characteristics, Environmental Concerns, and Management navigates these important environmental concerns while detailing opportunities for environmentally and economically beneficial utilization.
Maximise your garden, whatever you grow in it, with some Swedish expertise. Plants need nutrients to grow, flower and bear fruit, nutrients that can be found in offal, the sea, fire, rocks, rubbish and, of course, dung heaps. Tina Råman digs into every aspect of nurturing your soil, from chemistry and biology to history and philosophy, giving you practical advice, generous tips and above all masses of inspiration. She lifts the lid on old and reliable fertilisation methods and opens the doors to new resource-efficient and environmentally-smart cultivation techniques. Good Soil doesn’t look like a typical gardening book but it’s a book that everyone interested in gardening needs.
Presents advice on how to improve growing soil, discussing some of the current misconceptions about soil and providing the best methods for adding enhancements that will produce nutrient-dense foods.
"Eliot is the reason I’m cooking. . . . I’ve followed that path because Eliot made it possible, and exciting, to farm in the four seasons."—Dan Barber, chef "There is hardly a more well-known or well-respected name among organic farmers than Eliot Coleman."—Civil Eats Learn season-extending techniques and eat the best food—garden fresh and chemical free—all year long, with little effort or expense. If you love the joys of eating home-garden vegetables but always thought those joys had to stop at the end of summer, this book is for you. Eliot Coleman introduces the surprising fact that most of the United States has more winter sunshine than the south of France. He shows how North American gardeners can successfully use that sun to raise a wide variety of traditional winter vegetables in backyard cold frames and plastic covered tunnel greenhouses without supplementary heat. Inside, you’ll also learn: Composting techniques Simple Mineral Amendments Planning and preparing your garden site Seeds for four seasons How to build cold frames, high tunnels, and mobile greenhouses How to cope with snow How to create a root cellar and other storage techniques And much, much more! Coleman expands upon his own experiences with new ideas learned on a winter-vegetable pilgrimage across the ocean to the acknowledged kingdom of vegetable cuisine, the southern part of France, which lies on the 44th parallel, the same latitude as his farm in Maine. This story of sunshine, weather patterns, old limitations and expectations, and new realities is delightfully innovative in the best gardening tradition. Four-Season Harvest will have you feasting on fresh produce from your garden all through the winter. "The man, the farmer, the legend, is Eliot Coleman."—The Atlantic To learn more about the possibility of a four-season farm, please visit Coleman's website www.fourseasonfarm.com.
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.
In terrestrial ecosystems, soil microorganisms and soil animals are essential for litter degradation, soil formation and the availability of nutrients and trace elements. The measurement of biological soil parameters allows a rapid evaluation of the effects of chemical and physical influences due to pollutants or soil management. This book introduces a number of well proved methods for the analysis of carbon, nitrogen, phosphorus and sulfur cycles. It focuses further on the determination of the number and biomass of microorganisms, algae and animals in the soil. Particular emphasis is placed on the comprehensible and complete description of the experimental procedures.
Long-awaited second edition of classic textbook, brought completely up to date, for courses on tropical soils, and reference for scientists and professionals.
