Novel Method for Improved Quality of Turfgrass in Low-Light Environments

CTCN Keyword Matches:

Background: High intensity broad spectrum lighting equipment is currently in use to increase light intensity and extend photoperiods for turfgrass grown in low-light environments. The broad spectrum light generates tremendous heat and has high associated energy costs. The current invention uses light-emitting diodes (LEDs) as a viable lighting source for turfgrass. Technology Description: Researchers at the University of Tennessee have developed a novel method that utilizes energy efficient LEDs under optimized conditions to maximize turfgrass physiological parameters and quality in low-light environments. Preliminary data indicates the ability to dramatically enhance turfgrass physiology through increases in pigmentation (up to 70%) tissue mineral nutrient concentrations (up to 50%) and structural cellular components (up to 65%) by adjusting the quality of the light environment. Previously it was thought that LEDs would not be effective at lighting turf. The vertical angle of the turf blades and the limited diffusion of light from the diodes contributed to the assumption that LEDs could not adequately support turfgrass growth and development. Our invention shows a significant increase in turfgrass pigmentation mineral nutrients and structural components compared to conventional lighting systems. Patent Status: Patent pending
