| Abstract/Contents: | "Products that contain humic acid are frequently applied to creeping bentgrass (Agrostis stolonifera) on putting greens to improve turf health and are marketed to enhance nutrient uptake and possibly aid in retaining water in drought-prone environments. However, information on the role of humic acid in increasing soil water retention is limited. Pure organic acids - humic acid, tannic acid, and citric acid - were added to simulated creeping bentgrass putting greens at normalized carbon rates (250 mg C L-1) as solutions through an automated irrigation system. Volumetric water content, irrigation frequency, shoot and root growth, and tissue nutrient concentration of the turf were measured. None of the organic acid treatments improved water retention in the simulated greens. The humic acid treated greens required more frequent irrigation than the untreated greens indicating that they were drying out more quickly. Addition of humic acid did not result in higher tissue concentrations of nutrients nor increases in top-growth, dry root mass or the root:shoot ratio compared to the other treatments. Creeping bentgrass root length was greater in the greens treated with humic acid compared to the untreated control, but may be related to the lower soil water content." |
