Foreword

It is again our pleasure and professional opportunity to collaborate with the International Turfgrass Society (ITS) in the publication of these proceedings of the Third International Turfgrass Research Conference. Members of the American Society of Agronomy (ASA), the Crop Science Society of America (CSSA), and the Soil Science Society of America (SSSA) have actively participated in the Conference and thus all four collaborating societies share in presenting this written record in the conviction that it will provide useful documentation to the pursuit of turfgrass science in all parts of the world.

ITS is now more than a decade old. It was organized on the occasion of the First International Turfgrass Research Conference in Harrogate, England, in July 1969. The Second Conference, held in Blacksburg, Virginia, 19–21 June 1972, gave strong evidence of the truly international scope of turf grass science. Not only were there more scientists present from outside the United States than from within, but total attendance for that second conference was double the first.

And now the efforts of 91 scientists from 12 countries as reported during the July 1977 meetings in Munich, Germany, are recorded here. Thus, an expanding breadth and diversity of participants should provide the individual working as a turf grass researcher, extension specialist, classroom teacher, industry representative, or practicing turf grass professional manager with insights and perspectives that will strengthen each one's capacity to perform their chosen roles.

And again participation grows—in the 1977 conference there were 266 participants from 19 countries, an increase over the second conference of 74 participants.

We congratulate all those who shared in making this contribution possible, who labored to present this current summary of turfgrass science in a condensed source to assist all who pursue the field.

Preface

The future quality of life of man on this earth would be bleak without the aesthetic and functional contributions of turfs and ornamental plants. Man has chosen to cultivate turfgrasses for his benefit since the 13th century when turfs, as we know them today, started to evolve in England. The culture of turfs has increased steadily during the past four centuries in the industrialized countries of the world. The continuing effort to seek an improved quality of life is one that people will not readily abandon. In fact, the proper use of plants in environmental manipulation is an important aspect that is receiving greater attention than ever before. The willingness to invest time and money in maintaining turfs in order to provide a more favorable environment for human activities is evidence that turfs are an important aspect in a desirable quality of life.

In the future there will no doubt be changes in the types of turfs and the ways they will be maintained. These changes will be affected by higher energy costs for maintenance and more limited water supplies in many locations. We will need turf grasses and cultural practices that require less energy and water inputs, but at the same time continue to provide quality, functional turfs to meet the needs of a modern society. These projected changes present us with a challenge and justification for turfgrass research that is greater than it has ever been. As a science, turfgrass culture is just in its infancy compared to most areas of applied plant science.

The first concepts of an International Turfgrass Research Conference evolved during discussions between Bjarne Langvad and myself at East Lansing, Michigan, in the fall of 1966. The initial projection was that if 20 persons attended the first conference it would be judged successful. In fact, the First International Turf grass Research Conference held in 1969 at Harrogate, England, had 83 registrants representing 13 countries, with 99 papers presented. The second conference, held at the Virginia Polytechnic Institute and State University in the United States in 1973, had 247 registrants from 15 countries, with 80 research papers presented. Most recently, at the third International Turfgrass Research Conference in Munich, West Germany, 229 persons attended from 17 countries, with 95 papers presented. Participation at these conferences is strong evidence of the growing interest and activity in turfgrass research and education.

The Proceedings represents a permanent record of the concepts, research results, and descriptive information presented at the conference. It is particularly significant that this is the only publication which brings to gether a summary of the representative research activities currently being conducted throughout the world. The Proceedings facilitates communications among turfgrass researchers and educators.

As editor, I would like to express appreciation for the cooperation and very hard work of the Editorial Board members and Domenic Fuccillo in preparation of the Proceedings. The Associate Editors assumed responsibility for conducting the initial review for specific subject matter areas. Each paper was reviewed by a minimum of three turfgrass scientists, with at least one reviewer being from a European country. The cooperation of individual authors during the revision of manuscripts is also appreciated.

Two types of papers were approved for publication. The first portion of the Proceedings contains research papers which represent a new contribution to the scientific field and which test hypotheses through repli cated treatments that can be analyzed statistically to establish the validity of the investigation. The second group of papers are Observational Notes which make a contribution to the general knowledge in the field through descriptions of turf grass conditions or problems that are being reported for the first time. Finally, the meeting minutes and official actions of the International Turfgrass Society, a glossary of the turfgrass terms used in the Proceedings, and a subject index, are included in the back of the book.

As with its two predecessors, this Third International Turfgrass Research Conference Proceedings will serve as a valuable reference for turfgrass researchers, teachers, adult education instructors, research and de velopment specialists with private companies, and students of Turf grass Science. The ultimate goal is that through the information contained in the Proceedings the public will benefit from lower cost, simplified turfgrasses and cultural systems which still retain their important functional and aesthetic benefits and thus enhance the physical, mental, and environmental quality of life for the peoples of this earth.
