Root Zone Water Quality Model
Author: Lajpat AhujaPublisher: Water Resources Publication
ISBN: 9781887201087
Category : Technology & Engineering
Languages : en
Pages : 388
Book Description
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.

Principles and Practices for Petroleum Contaminated Soils
Author: Edward J. CalabresePublisher: Routledge
ISBN: 1351422030
Category : Technology & Engineering
Languages : en
Pages : 671
Book Description
Principles and Practices for Petroleum Contaminated Soils includes some of the best research and practical work done by top researchers in the field-both in industry and academia. It covers fundamental and advanced topics, such as analysis and site assessment, techniques (e.g., vacuum extraction, asphalt incorporation), and case studies. The book will interest anyone working with contaminated soils, ground water, and underground storage tanks. It will also be a valuable reference for regulatory personnel and environmental consultants at all levels.

Nitrogen Cycling in Ecosystems of Latin America and the Caribbean
Author: G. Philip RobertsonPublisher: Springer Science & Business Media
ISBN: 9400976399
Category : Science
Languages : en
Pages : 414
Book Description
The large and rapidly expanding body ofliterature related to nitrogen cycling in both managed and native terrestrial ecosystems reflects the importance accorded to the behaviour of this vital and often limiting nutrient. Research at the organism, ecosystem and landscape levels commonly addresses questions concerning nitrogen acquisition, internal cycling and retention. Goals for this research include increased agricultural productivity and a better understanding of human impact on local, regional and global nitrogen cycles. Nitrogen cycle research in tropical regions has a long and distinguished history. Research on different aspects of nitrogen cycling in ecosystems of the tropics has been carried out in many regions. In relatively few instances has there, however, been a focus on the biogeochemical cycles at the ecosystem level. The meeting resulting in this volume was an attempt to bring together existing information on nitrogen cycling in ecosystems of Latin America and the Caribbean and discuss this in an ecosystem context.
Impact of Pesticides on Farmer Health and the Rice Environment
Author: Prabhu L. PingaliPublisher: Int. Rice Res. Inst.
ISBN: 0792395212
Category : Business & Economics
Languages : en
Pages : 678
Book Description
The book covers the various aspects of the use of pesticides, their behavior, degradation, and impacts in wetland ricefields, and presents the results of surveys conducted in the Philippines and Thailand. It includes both bibliographic reviews and selected aspects of the experimental results of a research project on pesticide impacts in wetland ricefields. The first phase of the `Pesticide Impact' project was developed in the Philippines from 1989 to 1991. It was a multidisciplinary/collaborative approach involving scientists from IRRI, NRI (England), ORSTOM (France), UPLB (Philippines) who studied the effects of pesticides on the environment and on farmers' health, and the economical aspects of their use.
