Green Research



The research projects funded by the USGA break down into five categories:
Integrated Turfgrass Management

The golf course superintendent and staff work diligently to provide the best playing conditions possible; however, proper course management today also requires conserving natural resources and protecting the environment. Twenty-two studies funded at $1,406,065 over five years are underway to evaluate reduced pesticide use, increase our understanding of plant disease and insect pests, provide better plant resistance to both pest and climatic stresses, and improve overall management techniques for new and improved turf cultivars.




Physiology, Genetics and Breeding

The Nobel Prize-winning chemist Robert F. Curl of Rice University spoke for many of his colleagues in science when he proclaimed that the 20th century was "the century of physics and chemistry. But it is clear that the next century will be the century of biology." Thirty investigations funded at $1,892,323 over five years are ushering biotechnology into turfgrass species used for golf. This initial effort, along with conventional plant breeding improvements in bentgrass and bermudagrass, will enable scientists to reduce pesticide use in the long term. The USGA continues to collect and evaluate other promising grass species, such as seashore paspalum and inland saltgrass, which will allow poor quality water to be used in coastal and desert climates.




Golf Course Construction

For putting green turf to provide a fast surface and remain healthy, it must have adequate aeration, fertility, and moisture, while resisting compaction from foot and vehicular traffic. Over the last eight years, the USGA has funded research to better understand the physical, chemical, and biological nature of sand-based rootzones, as well as factors that affect the behavior of sands and sand mixes. Two studies are currently funded at $180,000 to evaluate the use of geotextiles and subsurface drainage systems, as well as subsurface irrigation technology to reduce construction costs and conserve water.




Environmental Impact

This area of research includes three distinct groups of studies. First, Fate and Transport research helps us understand what happens to pesticides and fertilizers applied to golf course turf. Today, the Green Section is sought after by government organizations to help provide guidance on policies concerning the registration and regulation of pesticides. Research efforts continue to evaluate entire golf course watersheds for their effects on water quality. Five studies funded at $662,031 over the five years address important environmental fate issues. The second area includes the Wildlife Links Program which is conducted in cooperation with the National Fish and Wildlife Foundation. These studies focus on the effect of golf course maintenance activities on birds, fish, amphibians and insect pollinators that are common to the wildlife habitat golf courses provide. The USGA contributes $100,000 per year to help co-fund seven studies National Fish and Wildlife Foundation. Third, the USGA funds the Audubon Cooperative Sanctuary Program (www.auduboninternational.org) at $100,000 per year.




Outreach

The USGA is involved in a wide range of activities that will affect the management of golf courses in the future. The Green Section funds small studies at the suggestion of its agronomists to solve regional turfgrass problems on golf courses. The Green Section worked closely with the Council for the Agricultural Science and Technology (CAST) panel that conducted the conference on "Water Quality and Quantity Issues for Turfgrasses in Urban Agriculture." The USGA assisted in the development of the Turfgrass Research Initiative, a long-term funding request to the US Congress for increasing the efforts of the USDA Agricultural Research Services in turfgrass research. To date, the US Congress has appropriated more than $3 million for research on important turfgrass problems. The USGA also works closely with the Golf Course Superintendents Association of America, Turfgrass Producers International, and the National Turfgrass Evaluation Program on two to three studies each year.

Every year golf course superintendents are introduced to new products in the marketplace. Without results from properly designed, objective research, superintendents are asked to make buying decisions based on word-of-mouth, previous experience from colleagues, or the representative of the product. Several surveys indicate that golf course superintendents desire side-by-side product evaluations to assist them in making product purchases. The result of this desire for this type of information is the Product Testing Program section of USGA's Turfgrass and Environmental Research Program. Currently, USGA is funding three projects that fall into this category of USGA-supported research.

The USGA and Chevron have committed to using the game of golf to encourage students in science, technology, engineering and math (STEM) disciplines. This commitment has led to the creation of extensive golf-focused STEM teaching tools, and has resulted in charitable contributions to support golf-related programs through Eagles for Education™

At U.S. Open Championships the Chevron STEM ZONE™ is an interactive experience highlighting the science and math behind the game of golf through a variety of hands-on exhibits and experiments.

The partnership has also produced educational materials such as the Science of Golf video series and a nationally-distributed newspaper insert which are provided to teachers as tools to enhance existing curriculum in schools. These lessons teach the science behind the USGA’s equipment testing, handicapping, and agronomy efforts.
