Download or read book Contaminants in Agriculture written by M. Naeem and published by Springer Nature. This book was released on 2020-04-25 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive volume covers recent studies into agricultural problems caused by soil and water contamination. Considering the importance of agricultural crops to human health, the editors have focused on chapters detailing the negative impact of heavy metals, excessive chemical fertilizer use, nutrients, pesticides, herbicides, insecticides, agricultural wastes and toxic pollutants, among others, on agricultural soil and crops. In addition, the chapters offer solutions to these negative impacts through various scientific approaches, including using biotechnology, nanotechnology, nutrient management strategies, biofertilizers, as well as potent PGRs and elicitors. This book serves as a key source of information on scientific and engineered approaches and challenges for the bioremediation of agricultural contamination worldwide. This book should be helpful for research students, teachers, agriculturalists, agronomists, botanists, and plant growers, as well as in the fields of agriculture, agronomy, plant science, plant biology, and biotechnology, among others. It serves as an excellent reference on the current research and future directions of contaminants in agriculture from laboratory research to field application.
Download or read book Soil and Water Quality written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can the United States meet demands for agricultural production while solving the broader range of environmental problems attributed to farming practices? National policymakers who try to answer this question confront difficult trade-offs. This book offers four specific strategies that can serve as the basis for a national policy to protect soil and water quality while maintaining U.S. agricultural productivity and competitiveness. Timely and comprehensive, the volume has important implications for the Clean Air Act and the 1995 farm bill. Advocating a systems approach, the committee recommends specific farm practices and new approaches to prevention of soil degradation and water pollution for environmental agencies. The volume details methods of evaluating soil management systems and offers a wealth of information on improved management of nitrogen, phosphorus, manure, pesticides, sediments, salt, and trace elements. Landscape analysis of nonpoint source pollution is also detailed. Drawing together research findings, survey results, and case examples, the volume will be of interest to federal, state, and local policymakers; state and local environmental and agricultural officials and other environmental and agricultural specialists; scientists involved in soil and water issues; researchers; and agricultural producers.

Download or read book Chemical Fate and Transport in the Environment written by Harold F. Hemond and published by Elsevier. This book was released on 2013-10-22 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical Fate and Transport in the Environment is a textbook for upper division undergraduate and graduate students studying environmental sciences in engineering, hydrology, chemistry, and other related disciplines. It covers the fundamental principles of mass transport and chemical partitioning, and the transformation of substances in surface water, in groundwater or subsurface environments, and in the atmosphere. Three major areas-surface water, ground water, and air-are covered, with descriptive overviews for each area. Each major section begins by describing environment: its controlling physical, chemical, and biological processes. The book also contains examples of common environmental problems and includes problem sets at the end of each chapter.Text that has been developed from a course taught at MITBroad-based coverage of the environmental sciencesA more rigorous treatment of transport than found in other textsExercise sets at the end of each chapterExamples of current environmental problems fully integrated into the textAmple references for access to the primary literatureNumerous illustrations throughout

Download or read book Root Zone Water Quality Model written by Lajpat Ahuja and published by Water Resources Publication. This book was released on 2000 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication comes with computer software and presents a comprehensive simulation model designed to predict the hydrologic response, including potential for surface and groundwater contamination, of alternative crop-management systems. It simulates crop development and the movement of water, nutrients and pesticides over and through the root zone for a representative unit area of an agricultural field over multiple years. The model allows simulation of a wide spectrum of management practices and scenarios with special features such as the rapid transport of surface-applied chemicals through macropores to deeper depths and the preferential transport of chemicals within the soil matrix via mobile-immobile zones. The transfer of surface-applied chemicals (pesticides in particular) to runoff water is also an important component.
Download or read book Soil Hydrology Land Use and Agriculture written by Manoj Shukla and published by CABI. This book was released on 2011 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is strongly affected by changes in soil hydrology as well as changes in land use and management practices and the complex interactions between them. This book aims to develop an understanding of these interactions on a watershed scale, using soil hydrology models and addresses the consequences of land use and management changes on agriculture from a research perspective. It includes case studies that illustrate the impact of land use and management on various soil hydrological parameters under different climates and ecosystems. It is suitable for researchers and students in soil sc
