| USGA Summary Points: | Water infiltration was slowed by topdressing with sand that contained a greater amount of fine sand; however, core cultivation was capable of offsetting this effect and increased water infiltration rate. Topdressing produced a firmer surface compared to the non-topdressed control at both levels of cultivation. Firmer surfaces were observed on plots that received the greatest rate of mid-season topdressing and were core cultivated. The Clegg Soil Impact Tester indicated that differences in surface hardness among sand sizes were only evident under non-cultivated conditions; surfaces were softest when topdressed with the fine-medium sand Sand topdressing increased the mass-content of organic matter (kg/m2 ) in the mat layer; however, the organic matter concentration (% by weight) was decreased (diluted) by topdressing sand. The 100 lbs. topdressing rate increased the mass-content and decreased the concentration of organic matter more than the 50 lbs. rate. Core cultivation reduced both the mass-content and concentration of organic matter in the mat layer. Medium-fine and fine-medium sands increased the fineness of sand within the mat layer. However, surface wetness (VWC) of the medium-fine plots was very similar to medium-coarse plots; whereas, the fine-medium plots frequently had much greater surface wetness than the other sands. Core cultivation was very effective at decreasing surface wetness of non-topdressed plots as well as plots topdressed with fine-medium sand. Core cultivation reduced the normalized difference vegetation index (NDVI) values compared to noncored plots throughout 2018. Similarly, plots topdressed at 100 lbs./1,000-ft2 had lower NDVI values than plots topdressed at 50 lbs./1,000 ft2 through 2018. Thus, more aggressive management of thatch accumulation lowered vegetative cover |
