Enormous increases in agricultural productivity can properly be associated with the use of chemicals. This statement applies equally to crop production through the use of fertilizers, herbicides and pesticides, as to livestock production and the associated use of drugs, steroids and other growth accelerators. There is, however, a dark side to this picture and it is important to balance the benefits which flow from the use of agricultural chemicals against their environmental impacts which sometimes are seriously disadvantageous. Agricultural Chemicals and the Environment explores a variety of issues which currently are subject to wide-ranging debate and are of concern not only to the scientific establishment and to students, but also to farmers, landowners, managers, legislators, and to the general public.

Agriculture in the United States is in the midst of a major transition motivated by economic and environmental factors. These include water quality and quantity, soil erosion, and the compatibility of agricultural production practices and the quality of the environment. Within the context of this change, US agricultural policy seeks to balance several objectives including an abundance of food and fibre at reasonable prices, economic security for agricultural producers, and conservation of natural resources. Agricultural chemical use and soil and water quality degradation associated with agricultural production are significant among the environmental problems confronting the United States. In fact, these are now perceived as environmental problems comparable to other environmental problems such as air quality deterioration and the release of toxic pollutants from industrial sources. While the growth of agricultural chemical use is an integral part of the technological revolution in agriculture that has generated major changes in production techniques, uncertainties about the health effects of agricultural chemicals are very important concerns. Severe soil degradation from erosion, compaction, or salinisation can destroy the productive capacity of the soil. It can also impair water quality from sediment and agricultural chemicals. This important new book looks at both of these significant issues - the relationship between agricultural chemical use and the environment and the relationship between soil and water quality degradation associated with agricultural production and the environment.

Due to the rapid increase in world population and improving living standards, the global agriculture sector is confronting with challenges for the sustainability of agricultural production and of the environment. Intensive high-yield agriculture is typically dependent on addition of fertilizers (synthetic chemicals, animal manure, etc.). However, non-point nutrient losses from agricultural fields due to fertilization could adversely impact the environment. Increased knowledge on plant nutrient chemistry is required for improving utilization efficiency and minimizing loses from both inorganic and organic nutrient sources. For this purpose, the book is composed of 19 chapters that highlight recent research activities in applied nutrient chemistry geared toward sustainable agriculture and environment. Topics of interest include, but are not limited, to speciation, quantification, and interactions of various plant nutrients and relevant contributories in manure, soil, and plants. This book outlooks emerging researchable issues on alternative utilization and environmental monitoring of manure and other agricultural by products that may stimulate new research ideas and direction in the relevant fields.

The increased use of chemical fertilizers and pesticides in crop production has adversely affected both the environment and the agricultural economy. Not only has it led to environmental pollution, but also the increasing costs of chemical inputs and the low prices received for agricultural products have contributed to economic unprofitability and instability. The International Symposium on Agricultural Ecology and Environment was organised in order to discuss ways of achieving the goals of economically and environmentally sustainable agriculture. It is apparent that a truly multidisciplinary effort is required and for this reason the meeting was attended by authors from many different disciplines and geographical locations. Although their papers reflect a wide diversity of agroecosystem types and examples, several common themes emerge: the increased importance of biotic control of ecosystem processes in lower input systems; the key role of soil organic matter in stabilizing nutrient cycling; the importance of agricultural landscape diversity and complexity; the importance of studying ecological processes in natural and agricultural ecosystems; the critical need to integrate socio-economic and ecological approaches.

Agriculture in developing countries has been remarkably productive during the last few decades; however, the production levels were achieved at the cost of placing more stress on natural resources and the environment. This volume brings together state-of-the-art applied, practical research related to agriculture, development, and the environment in the developing world. It attempts to distill current knowledge and to summarize it in readable form for development practitioners. Where possible, authors use specific examples to indicate which approaches have worked and which have not, under which conditions, and why.

Pollutants, Human Health and the Environment is a comprehensive, up-to-date overview of environmental pollutants that are of current concern to human health. Clearly structured throughout, the main body of the book is divided by pollutant type with a chapter devoted to each group of pollutants. Each chapter follows a similar format to facilitate comparison and discussion. For each pollutant, the authors describe the sources, pathways, environmental fate and sinks as well as known toxicological effects. Importantly, the second chapter on heavy metals and other inorganic substances deals with trace element deficiencies which can have serious problems for human health. Some rocks and soils are naturally low in some trace elements and intensive agriculture over the past half century has effectively mined many trace elements reducing their levels in soils and crops. The final chapter is a discussion about the various risk assessment frameworks and regulations covering the main pollutants. Comprehensive, up-to-date coverage of environmental pollutants of concern to human health Clearly divided into pollutant type with each chapter devoted to a different pollutant group Clearly structured throughout with the same format for each chapter to help facilitate comparison and discussion and enable readers to prioritise chemicals of concern Description of the sources, pathways, environmental fate and known toxicological effect Includes contributions from leading researchers and edited by a team of experts in the field

Pesticides have contributed impressively to our present-day agricultural productivity, but at the same time they are at the center of serious concerns about safety, health, and the environment. Increasingly, the public wonders whether the benefits of pesticides - `the perfect red apple' - outweigh the costs of environmental pollution, human illness, and the destruction of animals and our habitat. Scientists and government officials are suspected of promoting commercial interests rather than protecting human welfare.

The irrigated area in the Aral Sea basin totals about 7. 5 million hectare. Part of the water supplied to this area is consumed by the irrigated crop; the remainder of the supplied water drains to the groundwater basin, to downstream depressions, or back to the rivers. During its use, however, this drained part of the water accumulates salts and chemicals. The disposal of this polluted water causes a variety of (environmental) problems. If the percentage consumed water of the total water supply to an irrigated area (the so-called overall consumed ratio) can be increased, less water needs to be drained. This alleviates part of the related (environmental) problems. Further, if the overall consumed ratio for the above 7. 5 million hectare is improved, less water needs to be diverted from the rivers. Hence, more water can flow towards the Aral Sea. As mentioned above, part of the non-consumed irrigation water drains to the groundwater basin. Commonly, the natural discharge capacity of this basin is insufficient to handle this imported water. As a result, the groundwater table rises towards the land surface causing waterlogging. In (semi-)arid zones this waterlogging triggers a soil salinity problem resulting to a significant reduction in crop yields. The artificial increase of the discharge capacity, and lowering of the groundwater table, solves the soil salinity problem.

Many environmental problems resulting from atmospheric, land and water pollution are now widely understood. The combination of both improved technology and legislative pressure has led to a reduction in pollution from industrial practices in the West in recent years. However, sustainable development is dependent upon a new approach to environmental protection - clean technology. This book is in two parts. The first explores the ecological principles governing the function of ecosystems, sustain ability and biodiversity (Chapter 1) and the problems resulting from atmospheric pollution (Chapter 2), water pollution (Chapter 3) and land pollution (Chapter 4). For example, there is increasing international concern that the combustion of fossil fuels is leading to an increase in the levels of carbon, sulphur and nitrogen gases which pollute the atmosphere of our planet. The enhanced levels of carbon gases such as carbon dioxide may cause change in our global climate and, in tum, lead to flooding and loss of low-lying coastal regions. In addition, the deposition of sulphur and nitrogen oxides is believed to be the cause of 'acid rain' which has led to loss of fish stocks from upland lochs and damage to forestry plantations.
