Author: Agriculture and the Nitrogen Cycle
Author: Arvin MosierPublisher: Island Press
ISBN: 1597267430
Category : Science
Languages : en
Pages : 320
Book Description
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.
Organic Fertilizers

Languages : en
Pages : 386
Book Description
This book, Organic Fertilizers - From Basic Concepts to Applied Outcomes, is intended to provide an overview of emerging researchable issues related to the use of organic fertilizers that highlight recent research activities in applied organic fertilizers toward a sustainable agriculture and environment. We aimed to compile information from a diversity of sources into a single volume to give some real examples extending the concepts in organic fertilizers that may stimulate new research ideas and trends in the relevant fields.
Sweetness and Power

Category : History
Languages : en
Pages : 322
Book Description
A fascinating persuasive history of how sugar has shaped the world, from European colonies to our modern diets In this eye-opening study, Sidney Mintz shows how Europeans and Americans transformed sugar from a rare foreign luxury to a commonplace necessity of modern life, and how it changed the history of capitalism and industry. He discusses the production and consumption of sugar, and reveals how closely interwoven are sugar's origins as a "slave" crop grown in Europe's tropical colonies with is use first as an extravagant luxury for the aristocracy, then as a staple of the diet of the new industrial proletariat. Finally, he considers how sugar has altered work patterns, eating habits, and our diet in modern times. "Like sugar, Mintz is persuasive, and his detailed history is a real treat." -San Francisco Chronicle
Sorghum and Millets in Human Nutrition
Author: Food and Agriculture Organization of the United NationsPublisher: Food & Agriculture Org.
ISBN: 9789251033814
Category : Business & Economics
Languages : en
Pages : 196
Book Description
The publication is broad in scope and coverage, starting with the history and nature of sorghum and millets and dealing with production, utilization and consumption. It provides extensive information on the nutritional value, chemical composition, storage and processing of these foods. In addition, the anti-nutritional factors present in these foods and ways of reducing their health hazards are discussed. The authors have described formulations of various popular foods prepared from sorghum and millets and their nutritional composition and quality, and they have compiled many recipes for the preparation of foods from regions where sorghum and millets are important dietary staples.
Nutrient Use Efficiency: from Basics to Advances
Author: Amitava RakshitPublisher: Springer
ISBN: 8132221699
Category : Technology & Engineering
Languages : en
Pages : 417
Book Description
This book addresses in detail multifaceted approaches to boosting nutrient use efficiency (NUE) that are modified by plant interactions with environmental variables and combine physiological, microbial, biotechnological and agronomic aspects. Conveying an in-depth understanding of the topic will spark the development of new cultivars and strains to induce NUE, coupled with best management practices that will immensely benefit agricultural systems, safeguarding their soil, water, and air quality. Written by recognized experts in the field, the book is intended to provide students, scientists and policymakers with essential insights into holistic approaches to NUE, as well as an overview of some successful case studies. In the present understanding of agriculture, NUE represents a question of process optimization in response to the increasing fragility of our natural resources base and threats to food grain security across the globe. Further improving nutrient use efficiency is a prerequisite to reducing production costs, expanding crop acreage into non-competitive marginal lands with low nutrient resources, and preventing environmental contamination. The nutrients most commonly limiting plant growth are N, P, K, S and micronutrients like Fe, Zn, B and Mo. NUE depends on the ability to efficiently take up the nutrient from the soil, but also on transport, storage, mobilization, usage within the plant and the environment. A number of approaches can help us to understand NUE as a whole. One involves adopting best crop management practices that take into account root-induced rhizosphere processes, which play a pivotal role in controlling nutrient dynamics in the soil-plant-atmosphere continuum. New technologies, from basic tools like leaf color charts to sophisticated sensor-based systems and laser land leveling, can reduce the dependency on laboratory assistance and manual labor. Another approach concerns the development of crop plants through genetic manipulations that allow them to take up and assimilate nutrients more efficiently, as well as identifying processes of plant responses to nutrient deficiency stress and exploring natural genetic variation. Though only recently introduced, the ability of microbial inoculants to induce NUE is gaining in importance, as the loss, immobilization, release and availability of nutrients are mediated by soil microbial processes.
