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.
This book describes many important principles of fertilizer management and the environmental pollution problems due to the indiscriminate soil fertilization rate. The long-term impacts of organic or mineral fertilizer use have implications on soil fertility, crop yields, water quality, climatic change, greenhouse gas emissions, etc. Twelve chapters provide the state of the art of some important topics on subsistence agriculture, modern agronomy, and technological improvements which have sharply increased yields from cultivation, with a special emphasis on the sustainable management and environmental impact of commercial and nontraditional fertilizers. Without a doubt, this book is a valuable contribution to the agricultural sciences and it would not have been possible without the invaluable contributions, immeasurable acknowledgements, and recognized expertise from the authors.

"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.
Due to the rapid increase in world population and improving living standards, the global agriculture sector is confronting with challenges for the sustainability of agricultural production and of the environment. Intensive high-yield agriculture is typically dependent on addition of fertilizers (synthetic chemicals, animal manure, etc.). However, non-point nutrient losses from agricultural fields due to fertilization could adversely impact the environment. Increased knowledge on plant nutrient chemistry is required for improving utilization efficiency and minimizing loses from both inorganic and organic nutrient sources. For this purpose, the book is composed of 19 chapters that highlight recent research activities in applied nutrient chemistry geared toward sustainable agriculture and environment. Topics of interest include, but are not limited, to speciation, quantification, and interactions of various plant nutrients and relevant contributories in manure, soil, and plants. This book outlooks emerging researchable issues on alternative utilization and environmental monitoring of manure and other agricultural by products that may stimulate new research ideas and direction in the relevant fields.
About 5% of all U.S. cropland is currently fertilized with livestock manure. Expanded environmental regulation through nutrient management plans will likely lead to wider use of manure on cropland, at higher production costs, but with only modest impacts on commodity demand, or farm structure. While current use is limited, expanded gov¿t. support could lead to a substantial increase in manure use as a feedstock. However, current energy processes are unlikely to compete with fertilizer uses of manure, because they leave fertilizer nutrients as residues, in more marketable form, and because manure-to-energy projects will be most profitable in regions where raw manure is in excess supply, with the least value as fertilizer.

With contributions from over 70 international experts, this reference provides comprehensive coverage of plant physiological stages and processes under both normal and stressful conditions. It emphasizes environmental factors, climatic changes, developmental stages, and growth regulators as well as linking plant and crop physiology to the production of food, feed, and medicinal compounds. Offering over 300 useful tables, equations, drawings, photographs, and micrographs, the book covers cellular and molecular aspects of plant and crop physiology, plant and crop physiological responses to heavy metal concentration and agrichemicals, computer modeling in plant physiology, and more.
