Download or read book Nitrogen Management and Ground Water Protection written by Ronald F Follett and published by Elsevier. This book was released on 2012-12-02 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supplying crops with adequate nitrogen is vital to ensuring food supplies. Once nitrogen is added to the soil, it is subject to chemical transformations of the nitrogen-cycle including transformation to nitrate. Excessive amounts of accumulated nitrate may then leach out of the soil and could potentially enter and contaminate drinking water supplies. The purpose of this book is to examine the subject of nitrogen management and ground water protection.The issue of maintaining ground water quality is addressed primarily from an agronomic point of view. Topics covered include: health and economic aspects of nitrate in drinking water; nitrate sources; ground water nitrate in the USA and other developed countries; transport, leaching and accounting for nitrogen; soil, nitrogen, crop and water management; and nitrate in aquifer systems. The book contains a keyword index and is organized into thirteen chapters, each with appropriate references, tables and figures. Chapter authors are among the leading experts on the subject of nitrate and ground water quality.Readers to whom the book is directed include soil scientists and agronomists, agricultural engineers (irrigation and drainage), environmental scientists, agricultural policy makers, and hydrologists.

Available in PDF, EPUB and Kindle. Book excerpt: This timely work reviews the best current thinking on practicing sustainable agriculture, with contributions from agricultural, biological, environmental and social scientists. The emphasis is on temperate zones, with many of the contributions addressing U.S. agriculture. However, the principles explored here have application in any climatic or geographical region. The book discusses stewardship, biodiversity, reliance on mixed food systems and other approaches, always with a view toward reducing environmental degradation, maintaining economic viability and stabilizing rural communities.

Available in PDF, EPUB and Kindle. Book excerpt: The study of soils has taken on increased importance because a rapidly expanding population is placing demands on the soil never before experi enced. This has led to an increase in land degradation. Land degradation is one of the most severe problems facing mankind. Volume 11 of Advances in Soil Science was devoted entirely to this critical area of soil science. The editors of that volume, R. Lal and B.A. Stewart, defined soil degradation as the decline in soil quality caused by its misuse by humans. They further stated that soil degradation is a major concern for at least two reasons. First, it undermines the productive capacity of an ecosystem. Second, it affects global climate through alterations in water and energy balances and disruptions in cycles of carbon, nitrogen, sulfur, and other elements. Through its impact on agricultural productivity and environment, soil deg radation leads to political and social instability, enhanced rate of deforesta tion, intensive use of marginal and fragile lands, accelerated runoff and soil erosion, pollution of natural waters, and emission of greenhouse gases into the atmosphere. In fact, soil degradation affects the very fabric of mankind.

Download or read book The Role of Legumes in the Farming Systems of the Mediterranean Areas written by A.E. Osman and published by Springer Science & Business Media. This book was released on 1990-01-31 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legumes are an important source of protein for humans and animals. They provide nutritionally rich crop residues for animal feed, and playa key role in maintaining the productivity of soils particularly through biological nitro gen fixation. They are, therefore, of immense value in rainfed farming systems. The International Center for Agricultural Research in the Dry Areas (ICARDA) has a responsibility for research on food, pasture, and forage legumes. The Center also has the broad objective of improving livestock production in rainfed farming systems. Although food legumes have be~n known and grown by farmers in the WANA region for a long time, their productivity has remained low and variable. Forage legumes, on the other hand, are not so well known by farmers of the region, and their role in the farming systems is not so well understood. Thus, we need to develop the concept of using forage legumes as crops and to fit them into cropping systems. In its efforts to increase the productivity of food legumes and develop the legume-based crop/livestock systems, ICARDA has established a network of scientists in the different National Agricultural Research Systems in the region. To further strengthen this network, ICARDA convened a workshop on 'The Role of Legumes in the Farming Systems of Mediterranean Areas' in Tunis, Tunisia, 20-24 June 1988. This workshop was co-sponsored by UNDP, who also contributed funds for this publication.
