Abstract/Contents:"Although there are a number of management practices that vary between creeping bentgrass (Agrostis stolinfera) and ultradwarf bermudagrass (Cynodon dactylon x C. transvaalensis) greens, one significant cost associated with ultradwarf bermudagrass management is the need to cover greens periodically throughout winter months to prevent winterkill of the turf. Anecdotal evidence has shown patterns of winterkill that suggest that cover thickness or the presence of an air-filled gap under the covers improves winter survival, suggesting the ability of an air gap to maintain increased soil temperatures during extreme cold events. Many golf superintendents have used various ways to create an air gap beneath protective covers including the use of pine straw placed on the putting green prior to covering (Jared Nimitz, Peninsula Club, North Carolina, personal communication). Although the use of materials such as pine straw, in conjunction with covers, has been practiced by superintendents, the logistics and cost of applying and removing straw from greens is only feasible in cases where the greens are not required to be open for long periods in the winter months. An alternative to pine straw use may be the use of batting material placed underneath protective covers. The objective of this study was to investigate the effect of various weights of batting material on the soil temperature of an ultradwarf bermudagrass putting green at the University of Arkansas Research and Extension Center in Fayetteville, AR. Cover treatments were deployed when predicted low temperature minimums were forecast to reach -6 ┬░C and remained in place until the daily temperature was forecast to reach 10┬░C. Throughout the winter of 2018-2019, soil temperature at a depth of 2.5 cm did not differ between different weights of batting material, but all batting materials increased the 2.5 cm soil temperature compared to a cover alone."
