Role of soil moisture and organic matter in greens firmness

Bottom line: Greens firmness was strongly influenced by soil moisture, with wetter soils resulting in decreased firmness. Organic matter levels had a much less dramatic effect on firmness, but higher levels of organic matter did result in slightly decreased firmness. Overall, regardless of the organic matter content of greens, management of soil moisture is clearly critical in providing consistently firm putting greens.

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.
