Turf Research at UWA

  Our vision is to be the leading turf research group in Australia, and also recognised internationally

Background

 
Turf managers and society are seeking more efficient systems for delivering consistent and high-quality turf surfaces that enhance, rather than impact on, the environment.  The UWA Turf Research Program works in collaboration with the Australian Turf Industry to provide the quantitative information required to develop best management practices for water and nutrient use in turf culture.  Turf is a major component of the urban landscape in Australian cities; metropolitan Perth contained 13,500 ha of grassed areas in 1990.  The general community, as well as the Turf Industry, will benefit from best management practices that maximise turf quality, while minimising environmental impacts such as water consumption and nutrient leaching.
 
The research program has been developed, and managed, in consultation with industry groups.  A ‘Turf Industries Research Steering Committee’ was established in 1995, and this brought together stakeholders in the WA Turf Industry, Government, and Research arenas (Table 1) to set well defined goals.  In 1997, the UWA Turf Research Facility was established at Shenton Park, approximately 8 km west of Perth’s CBD.  The facility includes: (i) an innovative variable-speed lateral boom irrigator, (ii) soil-water monitoring equipment, (iii) a weather station, (iv) a series of lysimeters, (v) mini-rhizotron access tubes and image capture equipment, (vi) thermal camera, (vii) chromometer colour sensor, (viii) turf maintenance equipment, and (v) access to analytical laboratories at the Field Station and on the UWA Crawley Campus. 
 
The ‘Turf Industries Research Steering Committee’ has, for almost 20 years, successfully initiated, developed, co-funded, and managed research and extension activities in the priority areas as determined in collaboration with the Industry (Table 2).  The close involvement of industry groups has enhanced our research capacity and facilitated communication (flow in both directions) between research providers and stakeholder groups.
 
The program has been very successful, with new and relevant information now available to the Industry (Table 2).  A web-site http://www.plants.uwa.edu.au/research/turf provides details on the UWA Turf Research Team, current membership of the Committee, information on past and present projects, lists publications arising from our research, gives a ‘Fact Sheet’ on Minimising Nitrogen Leaching, and has the most recent volume of our newsletter available to down-load.
 
In order to meet the future demands of our stakeholders, and to promote continued development of the turf research program at UWA, the ‘Turf Industries Research Steering Committee’ periodically undertakes a strategic planning process.  This document summaries our vision for turf research at the University of Western Australia.
 

Key Stakeholders

  • Australian Turf Industry – it produces, distributes, installs, maintains, and provides products and advice to the end users of turf.  The Industry includes many businesses andindustry associations and bodies (e.g. Horticulture Australia Ltd, Turf Producers Australia, Turf Growers Association of WA, Golf Course Superintendents Association of WA, Parks & Leisure Australia, Landscape Industries Association, Irrigation Australia Ltd, Sports Turf Association of Australia (WA), WA Bowling Association, etc.)
  • Businesses providing products and services to turf growers and managers (e.g. water, fertilisers, irrigation equipment, agri-chemicals, compost, soil amendments, consultant advice, etc.), and industry associations (e.g. Fertiliser Association, WA Compost Association, Irrigation Australia Ltd).
  • Businesses with potential synergies (e.g. use of by-products, such as waste- or recycled-waters, organic and inorganic substances suitable for use as a soil amendment).
  • Bulk end users (e.g. local government, golf courses, ovals, sports grounds, parks, other grassed public open spaces, racing & gaming industry, etc.) and their relevant associations (see above and WA Local Government Association (WALGA)).
  • Individual end users (e.g. Homeowners).
  • Government departments and agencies – influence over users (e.g. Departments of Agriculture/Natural Resource Management, Department of Water, Department of Sports & Recreation, Department of Parks & Wildlife, Department of Environmental Regulation, Department of Education).
  • Relevant research investors (e.g. Horticulture Australia Ltd., Australian Research Council, Industry and Government).
  • Suppliers (e.g. Water Corporation) and regulators (e.g. Department of Water) of water resources.
  • Research, research training and education providers (e.g. TAFE, Universities, CSIRO, professional associations, public and private sector providers, etc.).
 
Diversity of representation by stakeholder groups is an important strength of the ‘Turf Industries Research Steering Committee’.

 Statement of Purpose

To work in partnership with the Australian Turf Industry to develop science-based best management practices for turf culture, with knowledge transfer to industry, government and scientific audiences.  Contribute to the development of the Australian Turf Industry and a sustainable environment for the citizens of Australia.
 

Function

 
  • To assess, and where appropriate initiate, and then conduct turf research projects to ensure that the results will be of maximum benefit to the stakeholders. 
  • To provide stakeholders with relevant information that will enable them to make informed decisions regarding establishment and maintenance of turf.
 
Committee members represent sectors within the range of stakeholders (and/or in some cases provide specific expertise).  Communication by committee members with their various sectors is essential to ensure that the decisions continue to address the needs of end users.
 
Objectives
 
  • To select projects that have relevant and achievable goals, will be completed within budget and on time, and which produce and disseminate new knowledge.
  • Secure adequate and on-going funding in collaboration with stakeholders in order to address Australia’s turf research needs.
  • Effective communication with industry to facilitate practice changes for economic and/or environmental benefits.
  • Provision of research student training opportunities.
  • To raise the profile of the research group, and ultimately to be recognised by practitioners and scientists, nationally and internationally, for excellence in turf research.
 
Achievement of the objectives listed above will be the hallmark of a successful program.  These objectives contribute to ensuring good returns to investors/stakeholders, and in establishing and maintaining credibility with stakeholder groups.  The objectives deal with the need to secure adequate resources to ensure an on-going program of excellence in turf research, of value to the industry and other stakeholders.
 
 

Desired Outcomes

 
  • A vibrant, multi-disciplinary, collaborative turf research group recognised for excellence in research and collaboration with the Australian Turf Industry.
  • Deliver new knowledge on turf sciences and management to Industry and Scientific audiences in WA, Australia, and world-wide.
  • Improved communication and sharing of knowledge amongst stakeholder groups.
  • Increased awareness amongst stakeholders of: (i) environmental and social benefits of turf, and (ii) responsible use of turf, in urban environments.
  • Maintaining an acceptable quality of turf with the minimal input of resources, through a better understanding of processes in turf and soils.
  • Australian Turf Industry recognised as leaders in best management practices for water and nutrients in turf.
  • Science graduates with knowledge in turf and related sciences, with an appreciation of industry needs – a future resource for industry, government and/or research providers.
  • Satisfied and motivated research staff, academic staff, committee members, and contributing partners. 
 
These outcomes will assist the further development of turf as an important sector within the Australian Horticulture and Landscape Industries, and enhance the quality of knowledge available to stakeholder groups in Australia.  Flow-on benefits to end-users include improved quality of turf surfaces and the environment. The outcomes contribute to the economic and social well-being of Australians. The sharing of knowledge in public forums (seminars and publications), will contribute to society at the local, national and international scales.

Practical outputs for industry include: 1. Data on turf water use against which turf managers can benchmark their irrigation scheduling.  2. Recommendations on rates of fly ash to use as a soil amendment, and understanding of the beneficial effects and environmental considerations.  3. Data on nutrient budgets for several fertiliser types and rates against which industry can benchmark fertiliser management to optimise turf quality, and minimise environmental impacts.  4. Information on potential water savings from use of soil-water sensor controlled irrigation scheduling.  5. Data on the benefits of soil wetting agents for water management and turf quality.  6. Data on the influence of mowing heights for turf water use.  7. Demonstration of responses of various soft-leaf buffalo genotypes to declining irrigation, alkaline soil, and contrasting renovation techniques.  8. The committee provides a ‘reference group’, our web site provides an easily accessible source of information for stakeholders, and the UWA research group provides a point of contact for the development of national and international collaborations and exchange of information.  9. Research results have been incorporated into various guidelines (e.g. Water Corporation brochures for homeowners, WA Turf Growers Association Code of Practice) and manuals (e.g. TurfSustain).  10. Our quarterly newsletter, web-site, field days, seminars and publications, are designed to ensure good communication with stakeholders and other groups.
