| USGA Summary Points: | Topdressing with medium-fine and fine-medium sands increased the fineness of sand within the mat layer, which explains the slower water infiltration of plots topdressed with sands containing a greater amount of fine sand. The much greater fine sand content in the mat layer of plots topdressed with fine-medium sand explains the greater capillary porosity measured in the mat layer of those plots as well as the wetter plots surfaces (VWC) observed during 2019. Core cultivation was capable of offsetting the effects of topdressing with finer sands. Water infiltration rate was increased by core cultivation and backfilling with a medium-coarse sand. Additionally, the surface wetness of plots was significantly drier on plots that were core cultivated. The organic matter concentration (% by weight) was decreased (diluted) by topdressing; however, mass-content of organic matter (kg/m2) in the mat layer was either increased or unchanged by topdressing. Core cultivation reduced both the concentration and mass-content of organic matter in the mat layer. Vegetative cover of plots (normalized difference vegetation index [NDVI]) was lower on core cultivated plots compared to non-cultivate during 2019. Similarly, plots topdressed at 100 lb/1,000-ft2 had lower NDVI values than plots topdressed at 50 lb/1,000 ft2 during 2019. Thus, vegetative cover was lower under more aggressive management of thatch accumulation with core cultivation and topdressing. |
