| Abstract/Contents: | "The particle size of sand can impact the ability to incorporate topdressing into the turf canopy, and unincorporated sand can interfere with mowing and play on putting greens. Two field trials were initiated to determine the effect of sand size on incorporation, turf quality, and root zone hydraulic properties. The first trial was initiated in 2010 on 'Greenwich' velvet bentgrass (Agrostis canina L.) turf maintained at 2.8mm.Treatments included topdressing biweekly at 0.15 and 0.3 L m-2 with medium-coarse and medium-fine sands and included an untreated control arranged in a RCBD with three replications. A second trial was initiated in 2011 on annual bluegrass [ABG; Poa annua L. f. reptans (Hausskn) T. Koyama] turf maintained at 2.8mm and evaluated the effect of sand size on anthracnose disease (caused by Colletotrichum cereal Manns). Treatments were arranged in a RCBD with four replications and included medium-coarse, medium and medium-fine sands applied at 0.15 L m-2 biweekly and a control. Digital image analysis was used to document the putting surface disruption due to unincorporated sand following topdressing events. Medium-coarse sand required more time for sand to dissipate from the turf surface after topdressing compared to the finer sands in the velvet bentgrass trial. Increasing topdressing rate (0.15 to 0.3 L m-2) dramatically increased the quantity of unincorporated sand remaining on the turf surface with medium-coarse sand; in contrast, no increase or only a slight increase in unincorporated sand occurred with medium-fine sand. Substantially more medium-coarse sand was removed by mowing than finer sands, which was supported by digital image analysis. Once sufficient sand accumulated within the turf canopy and thatch, all topdressing sands improved overall performance of velvet bentgrass and annual bluegrass turf. Additionally, topdressing with finer sand produced equivalent or better turf quality than plots topdressed with medium-coarse sand. Medium or medium-fine sand has not been observed to negatively affect soil hydraulic properties. The lack of negative effects of medium and medium-fine sand on measured parameters suggests that further research is warranted. Less disruption to putting surface at even higher topdressing rate may encourage golf course superintendents to apply adequate topdressing during summer when they normally would not." |
