Ozone treated irrigation water and turf quality

Bottom line: Can turf quality be improved through the use of irrigation water that has been treated with ozone? Preliminary results of a field trial that we conducted during 2011 showed that turf in ozone–treated plots indeed showed higher quality, suggesting that ozone treatment might improve turf quality. However, due to inconsistent irrigation distribution among the plots, the results were inconclusive.

Video: Siri Talks Turf

By now, you probably know that "Siri", the new iPhone 4S voice–assistant feature, can do everything from taking dictation to finding the closest Italian restaurants. But what does she know about turfgrass management? More than you might imagine, as PACE Turf's own resident super-nerd, Dr. Larry Stowell, shows you in the YouTube video, "Siri Talks Turf".

Rainfall impact on sodium leaching at Denver Country Club

In the July 13, 2011 Super Journal report, "Rainfall impact on sodium leaching at Denver Country Club" (1.3 MB pdf document), we show the dramatic and positive impact that spring rainfall can have on reducing soil sodium and salinity.

In short, we saw that a 2.5 inch rainfall, which occurred over a 36 hour period during the spring of 2011, resulted in a 41% reduction in sodium, and a 19% reduction in overall soil salts.

In addition to causing general stress to turf and potential issues with soil physical properties, high sodium and high salts are also associated with rapid blight, a disease caused by Labyrinthula terrestris. In years when winter and spring rainfall is low, it may therefore be necessary to leach greens with good quality domestic water in order to avoid reaching the maximum levels of 110 ppm sodium that can result in rapid blight infestation.
