The Doublecut with Micah Woods

An anonymous golf course superintendent wrote that they were "blown away by the quality of these surfaces with an amount of nitrogen I would’ve thought was far too small." I discuss this, and some of the changes I'm made in my thinking about what is "far too small," or not. Also, I discuss some of the preventative fungicide and herbicide applications on golf courses in Japan that keep the zoysia surfaces looking so clean in winter.

I spent nine days at the KBC Augusta golf tournament in 2023. In this episode, I introduce the blog post with the daily diary of my observations and measurements during the week.

Andrew McDaniel and I worked together at Habu CC in July 2001. We also worked together at the 50th KBC Augusta tournament in August 2023. I reflect on, and discuss, both of these, in this episode.

Andrew McDaniel joined me from the Keya GC maintenance office to discuss firmness measurements of putting greens, using a 4 ton roller on the greens, and why the greens make a crunching noise when walking across them.

I recorded this from Keya Golf Club, which will host the 50th KBC Augusta golf tournament on korai (Zoysia matrella) putting greens this week. I explained why I find this grass on putting greens so interesting, and some of the measurements I'll be making this week.

Jason Haines joined me for another #TurfMath episode to explain what the growth ratio is, how he uses it, and how he calibrates it.

One of the things you can do when you are able to express soil water content as a depth of water, and vice versa, is to express the water loss rate from the soil divided by the reference evapotranspiration. Now you've got a rough estimate of a site specific crop coefficient.

I explained how to do that in this post: https://www.asianturfgrass.com/post/hourly-evapotranspiration-soil-water-content-and-crop-coefficient/

For as long as I can remember, I've used the easy 1 mm = 1 L = 1% soil volumetric water content (VWC) relationship when converting between water use by grass, ET, irrigation, and soil VWC. Bill Kreuser shared the simple calculation to work this out in inches, for any rootzone depth.

I gave three reasons for my preference that sand topdressing amounts be expressed as a depth. One is consistency and standardization. Depth means the area to which the sand has been applied is already accounted for. Others include easy calculation and integration with #OM246, plus clear communication.
