Abstract: This experiment was designed to determine the efficacy of wetting agents against localized dry spot, effects on soil moisture content, and on root system growth and health in creeping bentgrass putting green turf. Soil moisture readings, NDVI, and general environmental data were collected from May 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. Initially there was some discrepancy between the 2009 and 2010 applications. By the end of the season, however, there were clear patterns among the canopy reflectance data, which were in agreement with the results from the 2009 application. While overall hydrophobicity levels remained high, there was a slight decline in hydrophobicity at all depths. Treatment effects on LDS were limited to the end of the season largely because of the wet summer. However, treatments did cause significant relief from LDS stress during this time of induced stress in comparison to the control group.
