USGA Summary Points:Control, topdressing, and cultivation treatments were continued for a 6th growing season. The May cultivation treatment was re-scheduled for 6 April to avoid severe work restrictions in 2020; this April timing was continued in 2021. Topdressing with all sand sizes produced acceptable turf quality; however, turf quality was often better on plots topdressed with finer sands and non-cultivated plots. Better turf quality was attributed to greater water availability in plots topdressed with finer sands and the greater turf cover (NDVI) throughout the growing season on non-cultivated plots. Greater water retention in plots topdressed with finer sands was associated with reduced surface hardness. However, this effect for finer sands was often not observed under cultivated conditions. Plots treated with core cultivation were typically the hardest surfaces. The procedure developed in 2020 to document the frequency and quantity of hand-watering was used in 2021. The method was further refined to distinguish between plots that require full plot watering versus spot watering. Preliminary analysis of these data indicated that plots with lower water retention require more irrigation to correct droughtstress of the entire plot or localized dry spots within plots.
