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.

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.

Symposium on the Physiology and Bio-Chemistry of Plant Productivity

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 steadily increasing cost of nitrogen fertilizer has resulted in more emphasis on basic and applied studies to improve nitrogen use efficiency in lowland rice.

Proceedings of the International Symposium on Frankia and Actinorhizal Plants, held in Montmorency Forest, Laval University, Quebec, Canada on August 5-9, 1984

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.

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.

ICARDA has the serious and urgent responsibility for increasing the quantity and availability of food in the extensive North Africa-West Asia region, and therefore must give high priority to optimising the use of soil water and nitrogen which are considered to be among the main limiting factors to production.

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.

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

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.
