Bøger i Developments in Plant and Soil Sciences serien

Report of an FAO/IAEA Technical Expert Meeting held in Rome, 13-15 March 2001

Suitable for scientists working on biological nitrogen fixation, soil microbial ecology and legume production, this volume reports the results of an FAO/IAEA Co-ordinated Research Programme (1992-1996), whose main objective was to develop molecular biological methods to study rhizobial ecology.

Symposium on the Physiology and Bio-Chemistry of Plant Productivity

The large and rapidly expanding body ofliterature related to nitrogen cycling in both managed and native terrestrial ecosystems reflects the importance accorded to the behaviour of this vital and often limiting nutrient.

Proceedings of a Meeting of the IUFRO, Working Party on Root Physiology and Symbiosis

The idea of addressing the problem of the genetic specificity of mineral nutrition at an international level arose four years ago in a proposal for this topic to be included in the program of the II Congress of the Federation of European Societies for Plant Physiology (FESPP) as a separate section.

Meeting of Commissions III and IV of the International Society of Soil Science jointly with the British Society of Soil Science

Proceedings of a Workshop on the Role of Legumes in the Farming Systems of the Mediterranean Areas, UNDP/ICARDA, Tunis, June 20-24, 1988

Proceedings of the International Symposium Plant and Soil: Interfaces and Interactions, Wageningen, The Netherlands, August 6-8, 1986

Proceedings of the International Symposium on Manganese in Soils and Plants held at the Waite Agricultural Research Institute, The University of Adelaide, Glen Osmond, South Australia, August 22-26, 1988, as an Australian Bicentennial Event

Proceedings of the International Conference on Effects of Crop Rotation on Potato Production in the Temperate Zones, held August 14-19, 1988 Wageningen, the Netherlands

The discovery of the reduction of acetylene to ethylene by nitrogenase provided the ideal answer to the problem by provid ing a rapid, specific, nondestructive, and inexpensive assay for nitrogenase activity.

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.

The use of organic residues as a means of maintaining and increasing soil fertility is of long-standing. The trend to conserve energy has led scientists to study the minimal tillage system, to find ways of replacing conventional inorganic fertilizers with natural organic prod ucts or microbial preparations, and to develop new composting methods.

The Third International Symposium on Nitrogen Fixation with Non-Legumes, Helsinki, September 2-8, 1984

Proceedings of the Second International Symposium organized by the University of Wisconsin, June 16-20, 1985

Proceedings of an International Symposium, June 9-12, 1987, Swedish University of Agricultural Sciences, Uppsala, Sweden

Third International Symposium on `Structure and Function of Roots', NITRA, Czechoslovakia, August 3-7, 1987

Proceedings of the 4th International Symposium on Nitrogen Fixation with Non-Legumes, Rio de Janeiro, Brazil, August 23-28, 1987

This symposium on 'Boron in Soils and Plants' completes a quartet of reviews of the behaviour in soils and plants of four trace elements, copper, manganese, zinc and boron, selected for their importance in agriculture.

Proceedings of an International Conference, Rehovot, Israel, October 2-6, 1994

Report of an FAO/IAEA/SIDA Coordinated Research Programme on Isotopic Studies of Nitrogen Fixation and Nitrogen Cycling by Blue-Green Algae and Azolla

Proceedings of the Third International Symposium on Plant-Interactions at Low pH, Brisbane, Queensland, Australia, 12--16 September 1993

This volume contains a selection of papers presented at the Rothamsted Millennium Conference "Interactions in the Root Environment - an Integrated Approach".

Countless other processes affecting the activity of soil micro flora and the inter actions between microorganisms and plants may pose an equal danger to soil equilibrium, but their potential hazards are often overlooked because of an insufficient understanding of soil microbiology on the part of scientists.

Proceedings of an International Workshop, Mayaguez, Puerto Rico, November 17-19, 1982

Broader in scope than classic references, this volume looks at the rhizosphere as a holistic entity by incorporating concepts from molecular biology. The text also identifies concepts that could lead to new management methods in ecological engineering.

It has long been recognized that soil organic matter is the key to soil fertility. But it has another property, the nature and extent of which have been the subject of argu ment and controversy ever since scientists began to study the soil, and that is its ability to affect growth directly, other than by providing nutrient elements.

The formation of roots is in some respects one of the least fundamentally understood of all plant functions. Pandanus trees tend to have stout aerial roots issuing from the bases of the long branches, while the tangle of roots around the trunk of many of the Ficus species is characteristic.
