The 13th International Plant Nutrition Colloquium is the latest in a series which commenced in 1954. This volume of the Proceedings begins with two keynote papers which review achievements in the field of plant nutrition and crop production in this century and discuss future developments in the science and in our society. Recent advances in plant nutrition are reviewed by three other invited papers from the aspects of innovative research technology, molecular biology and rice physiology. Nearly 300 shorter papers report and discuss findings in plant nutrition: mineral function, ion transport, molecular biology, deficiency and toxicity tolerance, diagnostic techniques, root function, N fixation, microorganisms, rhizosphere, fertilizer, environmental pollution, organic wastes, rice physiology, N and S metabolism, dry matter production and crop quality. Readers should gain an appreciation of current knowledge in all the aspects of plant nutrition relating to sustainable food production and the environment.

In the history of the International Plant Nutrition Colloquium from its first meeting in 1954, this meeting, the 13th Colloquium, is the first to be held in Asia and will be the last in the 20th century. The 20th century has seen huge changes in the number and activities of mankind. Our population has increased from around 1. 7 billion to more than 5. 8 billion and technological innovations have completely altered our way of living. As a consequence of such rapid change, we are facing many problems including changes in our environment of a global scale. But, while food shortage has been a serious concern to mankind throughout our history, serious food shortages in the 20th century have been confined to limited times and areas. As Lester Brown discusses in this volume, farmers have increased food production heroically on demand. We, the plant nutritionists should be proud of our support to the world''s farmers which has helped them make their achievement possible. During the 20th century, the science of plant nutrition also has achieved great progress as described by Jack Loneragan; it became established as a discipline firmly based in science, defined the chemical elements supporting plant growth, and has contributed to improvements in plant production and environmental quality, as readers will find in many contributions in this volume.
