| Abstract/Contents: | "Topdressing sand typically is applied at very low rates (dusting) to avoid interference with play and dulling of cutting edges. The objective of this study was to determine the effects of (1) eliminating coarse particles from topdressing sand (subsequently increasing proportions of medium, fine and very fine particles) and (2) core cultivation on the physical properties of the mat layer of a creeping bentgrass (Agrostis stolonifera) turf. This trial used a 3 x 2 x 2 factorially arranged randomized complete block design with four replications. Treatments were initiated in May 2016 on a 20-month-old 'Shark' creeping bentgrass turf mowed at 2.8-mm. The factors included sand size (medium-coarse, medium-fine, fine-medium), rate of topdressing during mid-season (2,441 or 4,882 kg ha-1 every 2 weeks), and cultivation (cored plus backfilled with medium-coarse sand or non-cored). Non-topdressed controls at both levels of cultivation were included for orthogonal contrasts. Volumetric water content (VWC) of the surface 0- to 76-mm depth zone was routinely measured during growing season. Infiltration rate using double-ring infiltration was measured in August of 2018 and 2019. Undisturbed, 76-mm diam. core samples were collected in May 2019 to characterize mat-layer depth, organic matter (OM) concentration, pore size distribution and sand size distribution. Core cultivated plots had substantially greater infiltration rates and reduced VWC compared to non-core plots. Mid-season topdressing at 4,882 kg ha-1 produced a drier surface than topdressing at 2,441 kg ha-1 but did not affect infiltration rate. Topdressing with medium-coarse and medium-fine sand were both effective at drying the surface; whereas, topdressing with the fine-medium sand resulted in a much wetter surface with a lower infiltration rate. Core cultivation and backfilling with medium-coarse sand offset these negative effects caused by topdressing with fine-medium sand. Results of the undisturbed core samples will be discussed." |
