| Abstract/Contents: | "The application and re-application timing of a surfactant has often been debated. Current practices have the surfactant application based on time intervals. Surfactant concentrations in the soil can vary based on the degradation of the surfactant by soil biota and leaching by rainfall; therefore, a time base interval is not ideal to base a surfactant application on. In order to determine the soil concentration of a surfactant, a field study and a greenhouse study were implemented. The field study examined the surfactant horizontal performance of several surfactants during dry down periods of no rain or irrigation. The greenhouse study tested the surfactant vertical distribution using lysimeters. The lysimeters were built based on the USGA recommendation for putting greens and had 4 TDR probes installed at different depths. The vertical distribution of watering was compared to the concentration of the surfactant that was extracted and measured. Samples of the leachate and extracted surfactant from the soil samples were measured by using a mobile Infrared, Near Infrared and Raman Spectroscopy. Results are showing that the watering amount will affect the concentration of the surfactant of the soil.The vertical distribution showed how the surfactant remained in the soil throughout the entire soil profile and not just at the top of the putting green. The vertical distributions are varying due to the amount of water. Results from the field study showed that different products effect the horizontal distribution differently. The amount of heat and water have an impact on the concentration as well. Therefore, the models are developed based upon the impact of the leaching and surfactant breakdown." |
