Book Description
PH. BOURDEAU Directorate-General Science. Research and Development. Commission of the European Communities. Brussels. Belgium We are living on a unique planet, the only one in the solar system where life exists. The very existence of life has modified the physical and chemical environment of the earth, its atmosphere and oceans, in a way that makes life sustainable. This system with its complex cybernetic mechanisms has been named GAIA by Lovelock. Man has always interfered with it on a more or less limited scale. This interference is now reaching global proportions such as climate modifications resulting from CO and trace gas 2 accumulation in the atmosphere or the destruction of stratospheric ozone, not to speak of global radioactive contamination. GAIA will probably prevail as a living system but it probably does not give much importance to man's survival as such, and it is man that has to take care of his own survival. In the ecosystem of Planet Earth, soils are the thin interface between lithosphere and atmosphere which constitutes the essential substrate for the terrestrial biosphere, the productivity of which far exceeds that of the oceans, even though the latter cover a much larger area than the continents. Soils themselves are complex systems. They develop through weathering of minerals, are colonised by living organisms which in turn modify their substrate making it suitable for other organisms. This induces a primary ecological succession which eventually reaches a climax, in equilibrium between climate, soil and the biological communities.

Book Description
Disposal of organic sludge and liquid agricultural wastes is a universal problem. Their production cannot be halted and as steps are taken to maintain or improve the quality of rivers and lakes it grows in quanti ty. The Commission's early awareness of the need for action to prepare for substantial growth in the Community's' sludge disposal problem led to the setting up of the COST 68 project to coordinate and guide European research and development work with particular emphasis on recycling sludge to agricultural land. Two years ago the field of research activi ties was extended to liquid agricultural wastes. This Symposium is the latest opportunity to provide a comprehensive review of the results of the project, to define current trends in practice and to establish by discussion the priorities for research over the next few years. The development of instrumentation and of analytical techniques during the period has extended our knowledge of the organic and inorganic constituents of sewage sludge and agricultural wastes and enabled us more readily to identify and measure the risks to which our general environment may be exposed when disposing of it. This evolution of understanding is a continuing process and an essential guide to the modification of disposal practices to achieve safer and more efficient operations. However, it is important to take a broad view of the application of research findings in the light of the considerable contrast in conditions in different parts of the world.

Book Description
Biogeochemistry of Trace Metals is a compendium of the most recent information available on the effects of trace metals in soil quality and its potential threat on the transfer of these contaminants to consumers. Most of the chapters in the book were presented as papers during the First International Conference on the Biogeochemistry of Trace Elements (formerly Metals in Soils, Plants, Waters, and Animals) held in Orlando, Florida in May, 1990. Topics discussed include background levels of metals in soils and/or plants (covering western Europe; temperate, humid Europe; and the People's Republic of China); metal cycling and transfer in the food chain in agroecosystems; uptake and accumulation of metals by bacteria, fungi, and invertebrates; mechanistic aspects of metals; the microbial aspects of soil selenium losses; and manganese sorption on soil constituents.

Book Description
Food and Natural Resources provides an understanding of the interdependency of food and natural resources that affect society. It is hoped that through these discussions a more complete understanding of these timely issues will emerge. This base of knowledge will help individuals and government leaders develop and implement the types of programs that will result in the effective use and management of land, water, energy, and biological resources for improved food production and a higher standard of living for everyone. The book begins by examining the intrinsic dynamics of natural ecosystems—especially the land, water, atmosphere, energy, and biological components. This is followed by chapters on the availability and interrelationships between population size, arable land, water, energy, and other biological resources; the loss of wild species of plants and animals; the availability of agricultural land for crops and livestock; and the impact of land degradation on food and other resources. Subsequent chapters discuss water use in agriculture; the mechanization of agriculture and food production; the principles and practices that can make agriculture environmentally and economically sound and sustainable; and the impact of population growth on the environment and food supply.

Book Description
Agrochemicals and agricultural practices have a tremendous impact on environmental quality, particularly their role in water quality degradation. Soil Processes and Water Quality examines principles and practices that minimize the risks of water pollution while enhancing agricultural intensification and productivity. It focuses on how agricultural practices-such as tillage methods, use of fertilizers and manures, cropping systems, and the use of agrochemicals and pest control measures-impact soil processes and affect water quality. Extensive coverage of such topics as water contamination by runoff, leaching, macropore flow, and sediments is also included. Rapid increases in the use of agrochemicals make Soil Processes and Water Quality an indispensable reference for soil scientists, water quality professionals, researchers, environmental chemists, agrochemicals professionals, government agency employees, academic instructors, agronomists, and students.
