A third objective - to aid in developing the potential of Tennessee Valley agriculture - is regional in scope.
Nitrogen is an essential element for plant growth and development and a key agricultural input-but in excess it can lead to a host of problems for human and ecological health. Across the globe, distribution of fertilizer nitrogen is very uneven, with some areas subject to nitrogen pollution and others suffering from reduced soil fertility, diminished crop production, and other consequences of inadequate supply. Agriculture and the Nitrogen Cycle provides a global assessment of the role of nitrogen fertilizer in the nitrogen cycle. The focus of the book is regional, emphasizing the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) in Kampala, Uganda, that brought together the world's leading scientists to examine and discuss the nitrogen cycle and related problems. It contains an overview chapter that summarizes the group's findings, four chapters on cross-cutting issues, and thirteen background chapters. The book offers a unique synthesis and provides an up-to-date, broad perspective on the issues of nitrogen fertilizer in food production and the interaction of nitrogen and the environment.
New York Times Book Review Editors' Choice An unsettling journey into the disaster-bound American food system, and an exploration of possible solutions, from leading food politics commentator and former farmer Tom Philpott. More than a decade after Michael Pollan's game-changing The Omnivore's Dilemma transformed the conversation about what we eat, a combination of global diet trends and corporate interests have put American agriculture into a state of "quiet emergency," from dangerous drought in California--which grows more than 50 percent of the fruits and vegetables we eat--to catastrophic topsoil loss in the "breadbasket" heartland of the United States. Whether or not we take heed, these urgent crises of industrial agriculture will define our future. In Perilous Bounty, veteran journalist and former farmer Tom Philpott explores and exposes the small handful of seed and pesticide corporations, investment funds, and magnates who benefit from the trends that imperil us, with on-the-ground dispatches featuring the scientists documenting the damage and the farmers and activists who are valiantly and inventively pushing back. Resource scarcity looms on the horizon, but rather than pointing us toward an inevitable doomsday, Philpott shows how the entire wayward ship of American agriculture could be routed away from its path to disaster. He profiles the farmers and communities in the nation's two key growing regions developing resilient, soil-building, water-smart farming practices, and readying for the climate shocks that are already upon us; and he explains how we can help move these methods from the margins to the mainstream.
Six Chemicals That Changed Agriculture is a scientific look at how the chemicals used in today's food production were developed, evaluated, and came to be in wide-spread use. From fertilizers to pest management, antibiotics to DNA, chemicals have transformed the way our food is grown, protected, and processed. Agriculture is the world's most important environment interaction, the essential human activity, and an increasingly controversial activity because of its use and presumed misuse of chemistry. The major characteristics of US agriculture for at least the last six decades have been rising productivity, declining number of mid-size farms, increasing farm size, an increasing percentage of farm production on fewer, large farms, increasing dependence of chemical technology and more developmental research being done by the agricultural chemical industry rather than by independent land-grant universities. Another equally important feature of modern agriculture is wide-spread suspicion of its technology by the public. The book will recount examples of this suspicion related to specific chemicals and present the essence of the suspicion and its results. - Offers an historical analysis of the discovery and development some aspects of the chemistry of modern agriculture - Addresses the advantages, disadvantages, desirable and undesirable results of the use of each of the chosen chemicals and compares and contrasts the real and frequently assumed problems of their use - Provides valuable insights into the history and application of these focused chemicals, enabling readers to apply the lessons to new agricultural chemical developments
