Abstract/Contents:"Sand topdressing is a routine maintenance practice on golf course putting greens. It is recommended that topdressing sands contain particles of similar diameter classes to those within the rootzone; however, use of high density turfgrass cultivars can make this challenging. Research was conducted in 2023 to compare the physical composition of topdressing sands to those within rootzones of creeping bentgrass (CBG; Agrostis stolonifera L.) and ultradwarf bermudagrass (UDBG; C. dactylon L. x C. transvaalensis Burtt-Davey) putting greens. Rootzone and topdressing sand samples were collected from 23 putting greens across Tennessee. Ten samples (10 cm x 1.9 cm) were extracted from rootzones using a soil probe and 250 g of topdressing sand was collected from stockpiles. Particle size distributions of rootzone and topdressing sands were analyzed via the ASTM F-1632-03 method. Particle size diameter data were used to calculate coefficients of uniformity (CU) for each sand sample. Both rootzone and topdressing sands from UDBG greens contained more fine (0.15 - 0.25 mm) and very-fine (< 0.15 mm) sand particles than those from CBG greens. Rootzone sand from CBG greens contained more coarse (0.5 - 1 mm) and medium (0.25 - 0.5 mm) particles than those from UDBG greens. However, topdressing sands for both species did not contain significantly different amounts of coarse (0.5 - 1mm) and medium (0.25 - 0.5 mm) particles. For CBG greens, CUs of rootzone and topdressing sand were not statistically different. Conversely, for UDBG greens, CU of rootzone sand was significantly greater than that of topdressing sand. Results are concerning given that continued use of uniform, fine textured, sands on UDBG greens may negatively affect edaphic conditions over time."
