Product Description
There is widespread public concern about the effects of nitrate derived from farming on water quality and public health. But research on nitrate during the past decade has revealed wide discrepancies between public perceptions and reality. The main problems from nitrate are ecological changes in coastal and estuarine waters and nitrous oxide in the atmosphere. This gas, largely derived from nitrate, is a threat to the ozone layer in the stratosphere and is also a greenhouse gas. This book builds on Farming, Fertilizers and the Nitrate Problem (CABI, 1991) by Addiscott, Whitmore and Powlson but has been restructured to take account of new developments and to bring out more clearly the role of politicians and economists in the 'nitrate problem'. ...

Comprehensive overview that's well written
This book caught my attention because of its title and my interest in nitrogen and the soil environment.It provided a well written overview of environmental aspects of soil nitrogen that revolves around good science.

Must read for anyone involved with basic issues surrounding soil nitrates and water quality or concerns about NOx gas emissions. ... Read more

Product Description
In recent years a number of long-term global food supply-demand projections have been made. Though there is considerable disagreement, all are unanimous about one point - that demand will double by the year 2025. This increase is due to the combined effects of population and income growth. As the purchasing power of millions of people in third world countries rise, the first thing they do is alter their diet to consume more fresh fruit and vegetables and more animal protein. Whether this planet has to grow three times as much food or "only" twice as much, growing it in a manner that protects the quality of the environment is the problem examined by this book. To attain the goal will require a high technology, science-based agriculture around the globe and this book explores the use of agro-chemicals and their effects. ... Read more

Product Description
This volume comprises the proceedings of the First International Rehovot Conference on Modern Agriculture and the Environment. It is a unique book, covering the broad spectrum of environmental problems related to agriculture, from chemical pesticides, means to reduce their utilization and some of the main alternatives to their overuse and misuse, through pollution caused by chemical fertilizers, aquaculture and heavy metals, treatment of wastewater, recycling of municipal and agricultural wastes, to modelling and bioremediation of agricultural pollution, as well as economic and policy aspects of natural resources. Illustrated with numerous international case studies, it is intended for agriculturists, researchers, students, policy-makers and environmentalists. ... Read more

Product Description
Modeling Chemical Transport in Soils: Natural and Applied Contaminants provides a comprehensive discussion of mathematical models used to anticipate and predict the consequences and fate of natural and applied chemicals.The book evaluates the strengths, weaknesses, and possibilities for application of numerous models used throughout the world. It examines the theoretical support and need for experimental calibration for each model. The book also reviews world literature to discuss such topics as the movement of sorbed chemicals by soil erosion, the movement of reactive and nonreactive chemicals in the subsurface and groundwater, and salt transport in the landscape. Modeling Chemical Transport in Soils: Natural and Applied Contaminants is an important volume for environmental scientists, agricultural engineers, regulatory personnel, farm managers, consultants, and the chemical industry. ...

Product Description
In order to quantitatively predict the chemical reactions that hazardous materials may undergo in the environment, it is necessary to know the relative stabilities of the compounds and complexes that may be found under certain conditions.This type of calculations may be done using consistent chemical thermodynamic data, such as those contained in this book for inorganic compounds and complexes of nickel.

*Fully detailed authoritative critical review of literature.
*Integrated into a comprehensive and consistent database for waste management applications.
*CD ROM version. ... Read more

Product Description
Worldwide concern for more environmentally friendly agriculture has provoked interest, particularly in developing countries, in agricultural biotechnology.While many developing countries have embarked on biotechnology research, few biotechnology applications have yet to reach the farmer's field.This study, based principally on country experiences, calls for an integrated approach to biotechnology, in which national priorities for research are firmly linked to the objectives set for, and problems confronting agriculture.It also argues in favor of public/rivate partnerships and, on the part of the donor community, for long-term funding. ...
