This book was released on 2007 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient irrigation of sand-based golf course putting greens is critical for minimizing water waste and maintaining a quality putting surface. The objective of the following study was to determine the minimum irrigation required to produce acceptable turf quality through the use of wetting agent (WA) applications and irrigation controlled by soil moisture sensors (SMS). Four irrigation treatments were controlled by SMS based on critically low soil moisture thresholds (12, 10, 8, and 6%). In addition, WA treatments were applied monthly. Average irrigation applied for the 12% threshold was 2.9, 6.1, and 11.1 times greater than the 10, 8, and 6% thresholds, respectively. However, lower thresholds treated with WA had better turf quality, less localized dry spot formation, and greater soil moisture uniformity than the untreated plots. In conclusion, water use can be reduced significantly without sacrificing turf quality by utilizing wetting agents and controlling irrigation with SMS technology.

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 Turfgrass written by John C. Stier and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 1348 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 2015-08-12 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for optimum Agrostis stolonifera var. palustris (creeping bentgrass) putting greens requires golf courses' to manage inputs closely. Challenges include low mowing heights, heat stress, traffic, and viable irrigation sources to manage creeping bentgrass. A factorial field experiment was designed on a Crenshaw putting green during the summers of 2010-2012 in East Lansing, MI comparing irrigation and mowing frequencies with and without a wetting agent. Daily irrigation replenishment of 30, 60, and 90% evapotranspiration (ET) measurements were compared for irrigation use efficacy while maintaining quality playing conditions and turfgrass health. Daily single and double mowing frequencies were compared for long-term aesthetics, pest populations, and playability when mowed at 0.3175 cm (0.125 in). Monthly applications of a wetting agent (Revolution(r)) were compared to untreated plots. Playability and overall aesthetics were characterized by weekly measurements of ball roll distance, percent volumetric water content (%VWC), and visual quality ratings (1-9). Annual soil measurements included water drop penetration (WDP) test and total microbial biomass (TMB).

Download or read book Topramezone written by Canada. Pest Management Regulatory Agency and published by . This book was released on 2010 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under the authority of the Pest Control Products Act, Health Canada's Pest Management Regulatory Agency (PMRA) has concluded that the addition of new uses on sweet corn to the product label Impact Herbicide, containing technical grade topramezone, is acceptable. Before registering a pesticide for food use in Canada, the PMRA must determine the quantity of residues that are likely to remain in or on the food when the pesticide is used according to label directions and that such residues will not be a concern to human health. This quantity is then legally established as a maximum residue limit (MRL). This paper reviews the level of legally established maximum residual level (MRLs) of topramezone in or on food, to be added to those MRLs already legally established, as well as presenting a table on proposed maximum residue limits.--Includes text from document.

This book was released on 2006 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management practices as well as for a better understanding of the environment. The availability of reliable information on soil morphology and other characteristics obtained through examination and description of the soil in the field is essential, and the use of a common language is of prime importance. These guidelines, based on the latest internationally accepted systems and classifications, provide a complete procedure for soil description and for collecting field data. To help beginners, some explanatory notes are included as well as keys based on simple test and observations.--Publisher's description.

This book was released on 2020-02-20 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.
