| Abstract/Contents: | "Application regimes of surfactants to turfgrass soils were investigated. Applications of Primer soil surfactant were made at 4, 6, and 8 week intervals to a creeping bentgrass stand grown on a sand-based soil. Two other surfactant products, applied at 2.6x the rate of Primer applications, were applied at the onset of the trial. Soil water repellency was monitored on a monthly basis. Differences in soil water repellency, measured by the water droplet penetration test (WDPT) were seen primarily in the top 2 cm of the soil profile. Comparison of treatments revealed that the two surfactants applied on a one-time basis were highly effective at lowering the water repellency at the 0 cm soil depth during the first two months of the trial. Soil water repellency data for these treatments after this date revealed WDPT values statistically equal to the control. The treatment most consistently reducing the WDPT compared to the control treatment, in the upper regions of the soil profile was the primer treatment applied at a 4 week interval. Applications of Primer on a less frequent basis were inconsistent with regards to lowering the WDPT compared to the control. This is an indication that the surfactant is breaking down in the soil, and that monthly applications are the most effective way to maintain reduced water repellency in the upper portions of the soil profile." |
