Abstract/Contents:Ultradwarf bermudagrass (Cynodon dactylonr x C. transvaalensis) putting greens continue to become more popular in colder regions, leading to an increased risk of sustaining injury from exposure to low temperatures. Management strategies, including proper fertility, moisture management, and the use of protective covers, decrease the likelihood of sustaining winter injury on putting greens, but winter injury has still been observed during harsh winters, even when all of the current best management practices were employed. The use of air gaps could be a potential tool to supplement protective covers. Insulating the putting surface with an air gap has the potential to provide warmer soil-temperatures than protective covers alone. The objective of this experiment was to examine the effects of various materials used to create air gaps under protective covers on soil temperature and winter protection of ultradwarf bermudagrass putting greens. The air gap treatments consisted of straw, synthetic batting, and drainage pipe placed under the protective cover and were compared to a cover only treatment and an uncovered treatment. The straw treatment (4 cm thick) provided significantly warmer soil temperatures than the cover only treatment for the duration of the coldest week of the year (1/20/20-1/26/20). The batting treatment (2.5 cm thick, 396 g/ m-2) showed promise at increasing soil temperature compared to the cover alone as well, but because of the mild winter experienced in 2019-2020, no air gap treatment had an effect on spring recovery.
