| Abstract/Contents: | Describes the signs of bentgrass decline, including thinning of turf canopy, yellowing of leaves, and death of roots. States that "the cause of summer bentgrass decline has been attributed to numerous factors, including high temperature, excessive or deficit soil moisture, poor soil aeration, and high relative humidity. High temperature is found to be the primary factor leading to SBD." States that "reducing soil temperature during the night may be easier and more economically feasible than during the day." Presents a study "to examine whether bentgrass growth could be improved by lowering soil temperature for 12 hours a day and whether nighttime temperature is more effective in improving bentgrass growth and quality than reducing daytime temperature." Results include that "plants exposed to reduced nighttime temperatures had a higher turf quality, shoot growth rate, leaf chlorophyll content, and a more extensive root system than those with reduced daytime temperatures at 70°F and 77°F...Generally, lowering soil temperature on shoot and root growth was more effective at the lower temperature (70°F) than higher temperature (77°F) and during nighttime than daytime. Therefore, soil temperature should be reduced to as low a level as possible and should be practiced at night, if possible, to achieve better plant growth and turf quality in the summer." Discusses methods for reducing soil temperature including fans, syringing, and subsurface cooling systems. |
