The present investigation was carried out in the period 1977-1981 at the Department of Soil Science and Plant Nutrition of the Agricultural University Wageningen, Netherlands.
The Symposium was organized by the Hungarian Ministry of Agriculture and the Central Research Institute for Chemistry of the Hungarian Academy of Sciences.
It is an established fact that we must continually increase and improve agricultural production if we are to meet even the minimum requirements of a growing popu- lation for food, shelter, and fuel.
The success of shifting cultivation systems developed by subsistence farmers testifies to the resilience of the "e;natural"e; soil-plant ecosystems to recover from the offtake of nutrients in crops and loss of soil struc- ture.
The fifth meeting of scientists working with Frankia and actinorhizal plants was held at Montmorency Forest of Laval University in Quebec from August 6-8, 1984.
The mission of the International Fertilizer Development Center is to increase food production through the improvement of fertilizers and fertilizer practices for the developing countries with special emphasis on tropical and subtropical agriculture.
This volume presents the proceedings of the Second International Sym- posium on Genetic Aspects ofPlant Minerai Nutrition, held in Madison, Wisconsin in 1985.
The steadily increasing cost of nitrogen fertilizer has resulted in more emphasis on basic and applied studies to improve nitrogen use efficiency in lowland rice.
On the occasion of its twenty-fifth anniversary, in 1985, the Netherlands Society for Grassland and Fodder Crops (NVWV) agreed to organize an International Symposium on a topic related to intensive grass and fodder production systems.
This volume certainly is a Conference Proceedings, the Proceedings of the NATO Advanced Research Workshop (ARW) on "e;Unsaturated Flow in Hydrologic Modeling"e; held at "e;Les Villages du Soleil"e; near ArIes, France from June 13 to 17, 1988.
This book provides an excellent illustration of the interrelationship between progress in scientific methodology and conceptual advances, and its publica- tion should contribute to further advances.
The NATO Advanced Research Workshop from which this book derives was conceived during Biotec-88, the Second Spanish Conference on Biotechnology, held at Barcelona in June 1988.
The main purpose of this book is to provide the theoretical background to engineers and scientists engaged in modeling transport phenomena in porous media, in connection with various engineering projects, and to serve as a text for senior and graduate courses on transport phenomena in porous media.
Nitrogen Economy in Tropical Soils presents an authoritative and comprehensive state-of-the-art review on soil/plant nitrogen inter-relationships, with special reference to tropical soils and crops in aerobic and anaerobic environments.
Over the last century the discharge of crude or partially treated sewage has probably been the most widespread, most documented and certainly the best understood form of pollution entering the aquatic environment.
Biotechnology for Waste Management and Site Restoration covers: waste management - solid, gaseous, liquid; site restoration - radioactivity, organics, toxic metals; educational, economic, social and business aspects; and international collaboration.
These Proceedings contain both oral and poster contributions to the first interna- tional conference"e; Field Screening Europe - Strategies and Techniques for On-Site Investigation and Monitoring of Contaminated Soil, Water and Air"e;, held in Karls- ruhe September 29 - October 1, 1997.
Food production remains the highest agricultural priority, subject to the constraint that it be done in harmony with nature, or at least with minimum environmental pollution.
Regional Approaches to Water Pollution in the Environment integrates knowledge and experience on pollution problems related to industrial, agricultural and municipal activities and former military sites, with special emphasis on the Black Triangle: the region situated at the borders between North Bohemia, Polish Lower Silesia and South Saxony.
It is the task of the engineer, as of any other professional person, to do everything that is reasonably possible to analyse the difficulties with which his or her client is confronted, and on this basis to design solutions and implement these in practice.
This book provides a state-of-the-art overview of the development of concepts and methodology of hydrological sys- tems analysis and its wide range of practical applications.
