Agrochemicals in Soil and Environment


Book Description

This volume ‘Agrochemicals in Soil and Environment: Impacts and Remediation’ is a comprehensive collection of important literature on agrochemical contamination. The main focus of this book is to point out undesirable changes in biological, physical and chemical characteristics of agricultural soils and its impacts on global agricultural crop productivity. Soil is one of the important resources of basic needs for our sustenance but due to various anthropogenic activities like urbanization and industrialization, the soil is losing its basic quality characteristics. Soil microorganisms, water holding capacity, minerals, salts and nutrients are under the direct threat due to agrochemicals therefore, agricultural sector is facing a serious challenge. Lack of proper knowledge and luxurious applications of agrochemicals resulting into degradation and deterioration of soil quality, loss of soil and crop productivity and threatening the food security. Therefore, it is imperative to develop indices, indicators and soil parameters for the monitoring and impact assessment of agricultural contaminants. Further, biotic and abiotic stresses and their tolerance mechanisms in plants in relation to the soil contaminants such as toxic pollutants, heavy metals, inorganic and organic matters, variety of pesticides, insecticides, herbicides, agricultural runoffs and solid wastes, and chemical fertilizers are also highlighted in this volume. This book also discusses causes of reduced agriculture productivity and suggests sustainable measures such as plant-based technologies, bioremediation and nanotechnology, that can be used to overcome the crop losses. The book is interest to research students, teachers, agricultural scientists, agronomists, environmentalists as well as policy makers.

Agriculture and the Environment


Book Description

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.
