“…However, most previous studies report that topdressing helps reduce thatch layers in established turf. Eggens (1980) observed that topdressing alone was an effective thatch control treatment on Penncross creeping bentgrass. Carrow et al (1987) found that topdressing ‘Tifway’ bermudagrass reduced thatch by 44 and 62% for one and two annual applications, respectively.…”

“…Frequent sand topdressing, aggressive vertical mowing, and core cultivation, are often used to alleviate the negative effects of excessive SOM (4,13,18,21). Topdressing alone has been shown to reduce thatch layers in ‘Penncross’ creeping bentgrass (12), ‘Tifway’ bermudagrass (9), and three different dwarf bermudagrass cultivars (28). Topdressing with sand serves to dilute the thatch and improves conditions for thatch decomposition (20,27).…”

Thatch accumulation can negatively impact ultradwarf bermudagrass putting greens. Frequent sand topdressing is often used to manage thatch accumulation; however, the high shoot density and aggressive growth of ultradwarf bermudgrass often inhibits the successful incorporation of sand topdressing into the turf canopy. Research was conducted to evaluate brushing, vibratory rolling, and brushing + vibratory rolling as methods of incorporating topdressing sand into the canopy of a ‘TifEagle’ ultradwarf bermudagrass putting green. Sand topdressing was applied biweekly during the summer with brushing, vibratory rolling alone, and brushing + vibratory rolling used as incorporation methods. Brushing + vibratory rolling resulted in less sand removed from the turf surface by mowing after topdressing than other treatments and produced higher surface hardness values than rolling alone or the control. However, neither thatch depth nor soil organic matter content were affected by topdressing incorporation method. This study shows that the combination of brushing + vibratory rolling can be a successful method of incorporating sand topdressing into dense ultradwarf bermudagrass putting greens.

“…Murray and Juska (1977) observed that coring reduced total organic matter in the thatch of Kentucky bluegrass (Poa pratensis L.), but the eff ect was short-lived. Eggens (1980) reported that monthly coring was more eff ective than monthly vertical cutting in controlling the thatch depth of creeping bentgrass; however, this study focused on thatch and did not include the mat layer when measuring depth. White and Dickens (1984) found no diff erences in thatch-mat depth between monthly hollow-tine coring and twice-yearly hollow-tine coring in bermudagrasses [Cynodon dactylon (L.) Pers.…”

Coring is a common cultural practice used on golf courses. The reported effects of coring alone on thatch–mat accumulation have been mixed. The objectives of this field study were to examine the effects of spring and summer coring on thatch–mat thickness and organic matter accumulation in creeping bentgrass (Agrostis stolonifera L.). Turfgrass color and quality and chlorophyll content were also monitored. The study site was ‘Providence’ creeping bentgrass grown on a sand‐based rootzone maintained as a putting green. Three coring regimes were assessed as follows: spring‐only coring (1.27‐cm‐diam. tines), spring plus three summer corings (0.64‐cm‐diam. tines), and a noncored control. At the end of the second year, spring‐only and spring‐plus‐summer cored plots had developed a 66 and 89%, respectively, thicker thatch–mat layer compared with noncored bentgrass. The total organic matter content (weight loss‐on‐ignition) in thatch–mat layers, however, generally was similar among all three regimes in both years. This indicated that the organic matter was diluted by inclusion of sand from topdressing or reincorporation of cores. Thus, organic matter concentration (i.e., gravimetric organic: dry weight of the cores) in the thatch–mat layer was much lower in plots of both coring regimes vs. noncored plots. Both spring‐only and especially spring‐plus‐summer coring caused substantial reductions in turf quality for a 2‐wk period. Spring‐plus‐summer coring resulted in increased chlorophyll levels as well as improved turf color and quality in late summer.
