Water use by turfgrasses is important because it impacts land use decisions and the potential use of natural turfgrasses in enclosed stadia. To determine turfgrass water use the evapotranspiration (ET) and photosynthesis rates were measured for different turfgrasses under different soil water conditions in a controlled environment with artificial lights. Application of abscisic acid reduced Kentucky bluegrass (KBG) ET, photosynthesis rates and it also reduced turfgrass growth and turfgrass greenness. Amongst tall fescue, Kentucky bluegrass and perennial ryegrass, tall fescue had the highest ET and photosynthesis rates. Five KBG cultivar blends varied in ET and photosynthesis rates when maintained at bin capacity, analogous to field capacity, and below bin capacity conditions. The KBG cultivar blend with the lowest ET in both conditions was the 'Turfgrass Water Conservation Alliance (TWCA)' blend. The KBG cultivar blend with the highest ET at bin capacity was Lowmow, while at below bin capacity was 4-Way. Turfgrasses in bins maintained at bin capacity used less water during daytime than turfgrasses in bins below bin capacity and had higher relative night time ET rates: 44.8% of daytime compared to 34.7 % for below bin capacity. The KBG cultivar blend bred for staying green in drought conditions, TWCA, had lower ET and photosynthesis rates than standard KBG cultivar blends.

Water is an increasingly valuable and limited resource, often perceived as being wasted on turfgrass. This much-anticipated second edition brings clear, current, science-based information on turfgrass management and water conservation to turf managers and researchers alike. Inside you’ll find a look at the current understanding of water use as well as new technologies being researched to reduce water use by turfgrass. Attention is paid to water quality and turfgrass as a key part of the urban environment, how integrating turfgrass with other landscape uses of water can be part of a conservation plan, and how various water qualities, including reclaimed water, can be part of a management plan. Chapters also cover •advances in drought, heat, and salinity stress tolerance •the role of water in modified root zone media and native soils •water management technologies •considerations for construction and management of urban green spaces including parks and golf courses •water depletion, pesticide and nutrient runoff A chapter summarizing the practical application of the science in each chapter rounds out the text, presenting the information in an immediately useable format. Includes 10 tables and figures, 20 color photos, a U.S. customary to metric conversion table, and an 8-page glossary.

With the increased use of alternative irrigation water sources on turfgrass and landscape sites, their management is becoming more complex and whole ecosystems-oriented. Yet few turfgrass managers have received formal training in the intricacies of irrigation water. Turfgrass and Landscape Irrigation Water Quality: Assessment and Management provide

Turfgrasses are used for many purposes such as golf courses, sports fields, and a variety of commercial and homeowner settings. Many other uses include other recreational activities, functional uses such as roadsides and airports, and for a variety of erosion control activities. Successful turfgrass management does not occur by chance. This book provides the in-depth knowledge and understanding of the science needed to accomplish this. Units (chapters) are arranged so as to build upon previous ones to help improve the reader’s understanding of the science and art of successful turfgrass management.

FUNDAMENTALS OF TURFGRASS MANAGEMENT THE PREMIER TURFGRASS MANAGEMENT HANDBOOK—UPDATED AND EXPANDED Fundamentals of Turfgrass Management is the longstanding authority on all aspects of the science and practices behind world-class turfgrass care. This fully revised Fifth Edition comes enriched by two new authors who share their cutting-edge research and real-world expertise on such topics as growth, soil testing, nutrition, herbicides, insecticides, and fungicides. Coverage throughout is refreshed with new illustrations and charts, as well as: Expanded coverage on professional lawn care programs, including cool-season and warm-season turfgrasses, establishing methods and costs, cultivation, sand topdressing, and more Enhanced material on the most up-to-date thinking and practices in weed management Brand-new chapters on the environmental, economic, and quality-of-life benefits of well-maintained turf, as well as the influence of light on turf health Whether you’re earning a degree or a paycheck, Fundamentals of Turfgrass Management, Fifth Edition remains the most complete, respected guidebook of solutions for developing and maintaining the finest-standards of turfgrass.

In order to face new challenges and unique situations in turfgrass management, students need to understand why specific management practices work and how to adjust them based on plants' requirements. Explaining the physiological needs of turfgrass plants, this advanced textbook outlines the management techniques that help supply those needs. Chapters discuss a range of practices and methods to cope with stress under both normal and less than optimum conditions, providing the decision making tools for improvement based on changing environmental conditions. This book presents a unique perspective of both science and practical management principles that will be applicable to all turfgrass sectors.

Turfgrass Soil Fertility and Chemical Problems is the best single-source, practical management tool that will help you overcome every fertility management challenge you face! Turfgrass Soil Fertility and Chemical problems will: * Help you pinpoint the effectiveness of fertilizer programs to ensure turfgrass quality, water quality, and environmental integrity * Help you understand a multitude of turfgrass species and cultivars and their complex nutrient responses or requirements * Explains site-specific fertilization, covering issues such as establishment on poor quality soils and the use of low-quality irrigation water * Show you how fertilization is important for environmental, traffic, and stress tolerance, as well as recovery * Show you how to apply the interpretation of soil, tissue, and water-quality test information in the development of fertilization regimes

Sustainability is a key framework for analyzing biological systems—and turfgrass is no exception. It is part of a complex that encompasses turfgrass interactions with different environments and the suitability of different turfgrasses for specific environments. In addition to its biological role, turfgrass—in the form of lawns, green spaces, and playing surfaces—brings beneficial sociological effects to an increasingly urbanized society. This book presents a comprehensive overview of current knowledge and issues in the field of turfgrass research and management, including the genetics and breeding, the diseases and pests, and the ecology of turfgrasses, and will appeal to a broad spectrum of readers.

Based on the successful seminar offered through the Golf Course Superintendents Association of America, Applied Turfgrass Science and Physiology cuts right to the authoritative information and know-how that will keep any turf area in optimal condition. Readers get an overview of turfgrasses, the characteristics of different varieties of turfgrasses; a look at plant responses to drought, temperature extremes, and shade stresses; and a comprehensive review of the latest information on how irrigation, mowing, fertilization, cultivation, and plant growth regulators and bio-stimulants affect turfgrass response to stresses and pests. Case studies and more than 165 illustrations reinforce text.
