Abstract

This experiment was designed to determine the efficacy of wetting agents against localized dry spot and hydrophobicity in creeping bentgrass putting green turf. Soil moisture readings, NDVI, and general environmental data were collected from June to September 2010. Water droplet penetration tests were conducted on 4 soil cores from each plot to determine the penetration test timings for each sample core. Due to high precipitation levels throughout the summer, localized dry spot development was limited. There was apparent results from the water drop penetration test later in the season, however, no strong pattern among the wetting agent treatments, and only some significant treatment effects on canopy reflectance. It was indicated that the PBS150 2x and 4x treatments had the best effect in reducing hydrophobicity.
