| USGA Summary Points: | Finer sands lowered field saturated hydraulic conductivity (Kfs)compared to the medium-coarse sand. Pooled across both cultivation levels, Kfs dropped 1.8 in h-1 in plotstopdressed with medium-fine sand and 2.5 in h-1 in plots topdressed with fine-medium sand. On average, plots that were cored cultivated twice per year increased Kfs 3.7 in h-1. Under relatively dry conditions on 28 September 2022, surface hardness responded to sand size on non-cultivated plots where finer sands reduced surface hardness; there were no differences among sand size on plots that were cored twice per year. Similarly, surface hardness was greater for plots receiving a 100-lb of topdressing sand compared to 50-lb when there was no cultivation; however, there no effect of topdressing rate was observed when plots were cored twice per year. The strong drying effect of coring twice per year appeared to override any effect of topdressing sand size and rate. The effect of sand size and topdressing rate on surface water content frequently depended on the level of cultivation (interaction); finer topdressing sand increased surface water content when plots were not cored; however, this response was often not observed (no difference) on plots that were core-cultivated twice per year. Similarly, plots topdressed at the 50-lb rate often retained more surface water than plots topdressed at 100-lb; however, this response was often not evident on plots that were core-cultivated twice per year. Under non-cultivated conditions, the number of hand-watering events decreased as the topdressing sand size became finer. There were nearly 44 fewer hand-watering events on the plots topdressed with fine-medium sand compared to plots topdressed with medium-coarse sand. The impact of sand size on the number of hand-watering events was much smaller under core-cultivated conditions; there were only 12 fewer hand-watering events on the plots topdressed with fine-medium sand compared to plots topdressed with medium-coarse sand. Undisturbed core (3-inch diam.) samples of the mat layers will be removed from plots in late winter or early spring 2023 using the methods performed during the USGA ID#: 2019-01-671 grant. These cores will be used to evaluate the surface bulk density, pore size distribution, organic matter content, and sand size distribution of the mat layers. This data will conclude the grant activities of USGA ID#: 2020-03-708 |
