The recording of my seminar about “How MLSN Works” is now available on YouTube. I want to correct something. At the very end, I misstated that irrigation water normally has 20 to 60 ppm (mg/L) potassium.

When this question arrived, I thought I could respond by showing a blog post I’d written in the past with the answer. “What kind of adjustments would you recommend to do when trying to use the MLSN on a Calcareous sand green profile and irrigation with water saline water with 1500 ppm and Pure Dynasty Sea Shore Paspalum and pH 8?

In my recent “How MLSN Works” seminar—slides here—I mentioned some other ways to learn more about MLSN. The four items I recommended are: The Humbug movie which explains MLSN and includes discussions with turfgrass managers who have used it.

I’ll be teaching a webinar on Friday, May 22, at 10 a.m. New York time, about How MLSN Works. The webinar is for the Amplify network and is free and open to everyone.

There is a new article about MLSN by Trygve Aamlid and Karin Juul Hesselsøe, available in three languages (including English) on the STERF website. I think this article is excellent.

Here are a few quotes: I’ve experienced the good times in our industry but more recently have seen a beleaguered industry, as our core players age, younger people don’t play, and revenues struggle to keep up with expenses …

Ben Kebby has started a Facebook group, Tuesday Evening Research Papers, or T.E.R.P.S. He shared this week an article I wrote in 2012 about understanding turfgrass nutrient requirements. I tried to write a 1 page update or overview to elaborate on that, but it spilled over to 2 pages.

I made a few small updates to the MLSN K calculator. This was the first Shiny app I made, back in 2014. You can see all of them—the Turf Twitter ones, the Hargreaves ET calculator, irrigation requirement demos, PACE Turf’s GP avatar generator, and more, at the ATC Shiny apps page.
