Abstract/Contents:"Shortage of fresh water for turfgrass irrigation and frequent drought stress are major limiting factors for golf course management in Virginia. Biostimulants have been widely used as a tool to improve turf quality, especially under environmental stress such as drought. Humic acid (HA) is a major component in many biostimulant products mainly because it possesses auxin-like activity and enhances root growth and plant stress tolerance. This study characterized two sources of humic acid (HA)-based biostimulants and evaluated their effects on root growth, viability, and drought tolerance of creeping bentgrass putting green turf. The two HA-based biostimulants, applied biweekly at two rates (0.2% and 0.3% HA), improved root viability of creeping bentgrass. The biostimulant treatments increased photochemical efficiency and leaf hormones (auxin and cytokinin), responses associated with the improvement of root viability and turf quality during drought stress. The results of this study suggest that appropriate rates and properly timed applications of HA-based biostimulants may improve creeping bentgrass performance as putting green turf, especially during summer stress."
