Plenary Lecture of the XIV International Plant Nutrition Colloquium: Food Security and Sustainability of Agro-Ecosystems through Basic and Applied Research

Proceedings of the 3rd International Conference on Mycorrhizas (ICOM3), 8-13th July 2001, Adelaide, Australia

In 2002, sixty international specialists met to discuss problems of high P-unavailability as a soil nutrient for crops, and the hazards of increased phosphate input to aquatic habitats from industrial and mining activities, sewage disposal, detergents, and other sources.

This volume is a compilation of extended abstracts of all papers presented at the 14th International Plant Nutrition Colloquium. Over 500 oral and poster presentations illustrate current knowledge and research emphasis in this subject, providing a comprehensive view of the state of plant nutrition research.

This publication comprises the proceedings of the first International Conference devoted to the structural roots of trees and woody plants. The structure and function of woody roots was also considered at different levels, from coarse to fine roots, with several papers discussing the interaction between roots and the rhizosphere.

During the next 30 years, farmers must produce 70% more rice than the 550 millions tons produced today to feed the increasing population. Rice suffers from a mismatch of its N demand and N supplied as fertilizer, resulting in a 50-70% loss of applied N fertilizer.

Proceedings of the Second Working Group Meeting of the Frontier Project on Nitrogen Fixation in Rice held in Faisalabad, Pakistan, 13-15 October 1996

Proceedings of a Workshop held at the Institute for Soil Fertility Research, Haren, the Netherlands, June 5-6, 1990

This Fertilizer Manual was prepared by the International Fertilizer Development Center (IFDC) as a joint project with the United Nations Industrial Development Organi zation (UNIDO).

Proceedings of a workshop organized by the Center for Development Research at the University of Bonn (ZEF Bonn), Germany, 7-10 June 1999

Proceedings of the International Symposium on Nitrogen Economy in Tropical Soils held January 9-14, 1994 in Trinidad, W.I.

This predicament is mainly caused by low inherent soil fertility, limited and unpredictable rainfall, frequent droughts, and wind erosion that accelerates soil degradation and desertification, compounded by To assure food production in the future, means rapidly growing populations.

Proceedings of the International Symposium `Fertilizers and Environment', held in Salamanca, Spain, 26-29 September 1994

Proceedings of the Second Working Group Meeting of the Frontier Project on Nitrogen Fixation in Rice held in Faisalabad, Pakistan, 13-15 October 1996

Proceedings of the 15th North American Symbiotic Nitrogen Fixation Conference held at North Carolina, USA, from August 13-17, 1995

This publication comprises the proceedings of the first International Conference devoted to the structural roots of trees and woody plants. The structure and function of woody roots was also considered at different levels, from coarse to fine roots, with several papers discussing the interaction between roots and the rhizosphere.

Selected Papers from an International Symposium held at East Lansing, Michigan, USA, May 1993

Ultimate success in exploiting the genetic capabilities of plants to grow in nutrient-stressed environments of the semi-arid tropics (SAT) requires a holistic view of food systems to ensure that genetic selections for improved yields on nutrient-poor soils will actually be adopted by farmers.

Proceedings of the International Symposium on Biological Nitrogen Fixation Associated with Rice, held in Dhaka, Bangladesh, November 28-December 2, 1994

Proceedings of a Workshop held at the University of Michigan Biological Station, Pellston, Michigan, U.S.A, May 29--June 2, 1993

Proceedings of the 14th Long Ashton International Symposium: Plant Roots - From Cells to Systems held in Bristol, UK, 13-15 September 1995

With the rapid increase in the use of fertilizer nitrogen, more attention has been paid to the rela tionship between nitrogen management and environmental quality and human of soil nitrogen has become more comprehensive with health.

Proceedings of the International Symposium on Boron in Soils and Plants, held at Chiang Mai, Thailand, 7-11 September 1997

Proceedings of the 8th Nitrogen Workshop, University of Ghent, Belgium, 5-8 September 1994

Proceedings of the 5th Symposium of the International Society of Root Research, held July 14-18, 1996, Clemson University, South Carolina, USA

Proceedings of the 7th International Symposium on Nitrogen Fixation with Non-Legumes, held 16-21 October 1996 in Faisalabad, Pakistan

Rice is the major staple food in Asia, and food security means rice security for most Asians.

The increasing global demand for food and other agricultural products calls for urgent measures to increase water use efficiency which is, with plant nutrient availability, one of the two main limiting factors in crop production.

Over forty years ago, concern was first focussed on cadmium contamination of soils, fertilisers and the food chain. Since then, substantial research data have accumulated for cadmium on chemistry in soils, additions to soils, uptake by plants, adverse effects on the soil biota and transfer through the food chain.
