TLI Research Areas
• Cultural Impacts of Natural Grass - Research that includes, but is not limited to, societal health and well- being, fitness, athletic field safety, socioeconomics, consumer attitudes, etc.
• Environmental Awareness of Natural Grass - Research that includes, but is not limited to, carbon sequestration, heat abatement, pollution entrapment, soil remediation, run-off reductions, etc.
• Natural Grass Input Reductions - Research that includes, but is not limited to, drought tolerance, reduced water use, nutrient requirements, traffic tolerance, integrated pest management, etc.
• Extending Harvested Shelf-Life of Natural Grass • Reducing Production Costs of Natural Grass
• Natural Grass Research Communication & Education - Information that can be used to develop content on Te Lawn Institute website for educating policymakers, homeowners, and the general public on turfgrass science, management, impacts, etc. Tis can include literature reviews on environmental impacts, turfgrass benefits, region-specific turfgrass selection and management, weed/insect/disease control, and more.
Tis year, the committee received five research proposals focused on items such as artificial turf risks, integrated pest management practices, harvesting sod on plastic, wetting agents, and thermal sensors for monitoring drought stress. Te Lawn Institute Research Committee met on Tuesday, February 19, in Charlotte, NC, during the TPI 2019 International Education Conference to review, discuss, and vote on these research proposals. Te university research projects listed in Table 2 were funded for 2019. Tese projects represent a wide range of topics that can benefit TPI members both locally and globally. Projects continuing from 2018 include those such as turfgrass water use, urban heat islands, runoff, and cooling effects, while a new project on using wetting agents to improve sod establishment success can provide practical and immediate benefits to TPI members.
Documenting Water Use for Turfgrasses in The United States
($66,197, Final Report) Irrigation needs were measured for lawn grasses started from sod in six states: Riverside, CA; Logan, UT; Dallas, TX; St. Paul, MN; Knoxville, TN; and Storrs, CT. Grass species used were those acclimated to the region: CA = bermudagrass, seashore paspalum, and tall fescue; UT = Kentucky bluegrass, fine fescue, and tall fescue; TX
