Available in PDF, EPUB and Kindle. Book excerpt: Rapid population growth in arid regions of the western US is placing increased demand on water resources. Variability in precipitation and common occurrence of drought have promoted scrutiny of water use in urban lawns and gardens. However, few reliable measurements of water use of these landscapes exist. Quantifying the amount of water used vs. required by landscapes such as turfgrass would allow significant water conservation. Evapotranspiration (ET) is affected by biophysical factors such as: available energy, turbulent mixing, saturation deficit, soil water, and stomatal conductance. In order to simulate the water use by turfgrass, the relative importance of these processes must be determined for this environment. This study measures ET rates for Kentucky bluegrass using eddy covariance techniques, to quantify water use under various conditions. The results are combined with a coupled form of the Penman- Monteith Equation to determine which biophysical factors affect the ET rate under various atmospheric conditions, especially the advection of heat and saturation deficit from the regional atmosphere. In addition, changes in ET and other properties of the vegetation were monitored during a period of reduced irrigation or dry-down. These results will help determine the amount of water such landscapes actually need.
Download or read book Turfgrass Water Conservation written by Stephen T. Cockerham and published by UCANR Publications. This book was released on 2011-01-01 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Deficit Irrigation of Kentucky Bluegrass for Intermountain West Urban Landscapes written by Hang T. T. Duong and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to end users irrigating with excess water, water conservation of turfgrass can make a large impact in urban water conservation by reducing water applied while still maintaining visual appearance. This study was conducted to determine if Kentucky bluegrass (Poapratensis L.) can be deficit irrigated to maintain minimum acceptable appearance while conserving water. The study investigated water stress in terms of stomatal conductance, chlorophyll index, leaf temperature and predawn leaf water potential at the point of water stress, or where visual quality no longer meets expectations during dry down conditions. Water use was measured over well established Kentucky bluegrass with an eddy covariance system that was validated with soil water measurements. Turfgrass was irrigated at 80% of reference evapotranspiration based on allowable depletion of 12 mm of soil water during growing season that was considered to be well-watered. Two dry downs were conducted over a two-year period (early and late summer). Turfgrass was allowed to dry down without irrigation until visual quality reached the minimum acceptable points (score 9́Þ 6). During drying periods, visual rating, chlorophyll index, predawn leaf water potential, and leaf temperature with stomatal conductance rapidly decreased once stomatal conductance fell to approximately half of well-watered levels. Both soil water content and evapotranspiration had weak correlation with stomatal conductance; however, stomatal conductance tended to have higher correlation with the change in soil moisture than with the change in crop evapotranspiration. Soil water use and eddy covariance data in terms of crop evapotranspiration had high correlation. The plant water use factor ranged from around 0.8 to 1.1 under well-watered condition corresponding to visual rating from 7 to 9. At the minimum acceptable point of visual rating, which is 5.5 to 6, the plant factor ranged from 0.65 to 0.87. This value of plant factor is quite high at this point. Even when Kentucky bluegrass went below acceptable visual quality, the grass still used significant amounts of water with the plant factor value ranging from 0.6 to 0.8. The data suggested that deficit irrigation cannot be applied with Kentucky bluegrass in the Intermountain West area.

Book excerpt: 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.
Download or read book Constructed Climates written by William G. Wilson and published by University of Chicago Press. This book was released on 2011-02-15 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: As our world becomes increasingly urbanized, an understanding of the context, mechanisms, and consequences of city and suburban environments becomes more critical. Without a sense of what open spaces such as parks and gardens contribute, it’s difficult to argue for their creation and maintenance: in the face of schools needing resources, roads and sewers needing maintenance, and people suffering at the hands of others, why should cities and counties spend scarce dollars planting trees and preserving parks? In Constructed Climates, ecologist William G. Wilson demonstrates the value of urban green. Focusing specifically on the role of vegetation and trees, Wilson shows the costs and benefits reaped from urban open spaces, from cooler temperatures to better quality ground water—and why it all matters. While Constructed Climates is a work of science, it does not ignore the social component. Wilson looks at low-income areas that have poor vegetation, and shows how enhancing these areas through the planting of community gardens and trees can alleviate social ills. This book will be essential reading for environmentalists and anyone making decisions for the nature and well-being of our cities and citizens.
