Independent FAIR WATER II Trial Highlights Fairway Drought Performance

Independent research carried out at the NIBIO Turfgrass Research Center in Norway has highlighted ICL’s H2Pro TriSmart and Syngenta’s Qualibra among seven commercially available soil surfactant technologies evaluated under prolonged drought conditions.

The work forms part of the STERF-funded FAIR WATER II project, supported by The R&A Golf Course 2030 initiative and the German Greenkeepers Association (GVD), investigating practical drought management and water-use strategies for golf course fairways across Northern Europe.

During the severe 2024 drought period, untreated plots required 116 mm of irrigation water to maintain the intervention threshold, compared with 90 mm for plots treated with H2Pro TriSmart. This represented a statistically significant 22% reduction in irrigation water use versus untreated turf.

Alongside lower water use, H2Pro TriSmart maintained strong turf quality, green grass cover, and soil moisture performance throughout the drought period, with the trial paper describing it as delivering the “best all-round performance” under the conditions tested.

Within the same controlled rainout shelter trials at the NIBIO Turfgrass Research Center Landvik in Norway, Syngenta’s Qualibra was recognised for providing the “best overall visual appearance after prolonged drought”.

As golf courses continue to face increasing pressure around water availability, irrigation costs, and prolonged dry periods, the FAIR WATER II project is also assessing approaches including thatch management, deep aeration, and the use of brackish or recycled irrigation water.

Dr Andy Owen, International Technical Manager for ICL, said:

“Independent trial work like FAIR WATER II provides valuable practical insight into how different technologies perform under prolonged drought stress. It is encouraging to see H2Pro TriSmart recognised for reducing irrigation water requirement while maintaining turf performance, alongside the visual turf quality delivered through Qualibra.”
