| Abstract/Contents: | "Historically soil wetting agents have been applied using a calendar-based approach on sand push up greens. The calendar-based approach does not consider microbial degradation of the wetting agent that varies throughout the year. Quantifying the longevity of soil wetting agents based on a measure like air-temperature based growing degree days could help to ensure more consistent water uptake throughout the season. This study was performed on creeping bentgrass sand push-up greens at the Jim Ager Memorial Junior Golf course in Lincoln, NE from April 2023 to October 2023. Soil wetting agents were applied on a monthly interval and soil samples were collected every 30 to 50 GDD (base 0C) from 250 to 900 GDD on all nine greens. Soil samples were air-dried for two weeks and then water drop penetration tests were performed to quantify the variability of the water uptake in each of the greens. The data were subject to a plateau to simple linear piecewise regression model to quantify the longevity of the efficacy of the wetting agent. Initial results suggest that the soil wetting agent used in the study maintained a consistent efficacy and low variability up until around 560 - 630 GDD (base 0C). Future work will quantify the break points at different application rates and with different soil wetting agent chemistries." |
