When soil temperatures rise above 30°C cool-season grasses such as bentgrass and perennial ryegrass become stressed. As a result, there is a subsequent loss of root functionality and turf struggles. The use of turf fans provides much-needed air movement in areas with poor circulation and stops stress conditions from developing.
In certain situations these stresses such as high humidity can lead to the development of turf diseases like pythium. We can supply two alternatives, the sportsground unit (P1) and a golf courses (P2) option.
In the USA some golf courses have as many as 40 permanent fans while others have only one or two for problem greens. In stadiums, these are generally set up in banks of 8 to ensure optimal airflow.
Research into turf fans shows:
- They reduce the soil temperature and increase root length density on creeping bentgrass putting greens. Turf fans lower the surface temperature of a green by up to 3°C, and lower the soil temperature by 1° to 2° C.
- Reductions in disease pressure due to increases in wind velocity.
- Fans dry the soil and reduce turf leaf wetness and
- They improve the quality of shaded greens.
The P1 Fan for sportsgrounds.
As stadiums are designed to enhance the viewing experience they are being constructed with poor natural air circulation. The P1 TurfFan is designed to create airflow to give turf grass the best conditions to grow.
The P2 Fan for golf courses.
Limited air movement is one of the major factors contributing to summer bentgrass decline and more than 20 years of research have demonstrated that fans improve air circulation and sustain the quality of creeping bentgrass putting greens in the summer months. The P2 TurfFan is designed to cool golf greens and is highly mobile with both a mains and auxiliary power option with usually one being adequate per green.
The video below shows how fans can lower the surface temperature of a golf green and how to use them when the turf needs it.
