Wetting agents trial shows usefulness in the rain

Syngenta says trials with the new Qualibra wetting and water conservation agent have highlighted the beneficial effects of managing moisture deeply and evenly through the soil profile.

Qualibra trials undertaken at De Vere Carden Park Golf Club in Cheshire, as part of the Turf Science Live event organised by Syngenta, Everris and Jacobsen, showed surface water can be moved away quickly, to leave surfaces drier and firmer. Qualibra was not holding excess moisture in the soil profile, the trials also found.

Syngenta's Dr Simon Watson reported moisture readings over two days on a treated green, showed the Qualibra wetting agent facilitated water movement throughout the soil profile, with no accumulation of excess moisture at depths of 3.8, 7.6 or 12cm. Importantly, the standard deviation on the readings across the green was significantly less at all depths showing that moisture content was also less variable down through the soil profile following the Qualibra treatment.

"At 7.6cm depth the average moisture was 23% in the Qualibra treated area, and 26% in the untreated," he said. "However, the standard deviation on the Qualibra area was just 1.8, compared to 3.7 without treatment.  That indicates moisture content is more consistent at this depth in the soil profile across the green.

"It reinforces the importance of maintaining a wetting agent programme through wet periods.  When you combine the penetrant action built-in with the moisture retaining capability of the polymer in Qualibra, you get the best attributes of both and the opportunity to encourage improved plant health and playing surface performance," he added.
