I went for a run to the ocean at Cerro Gordo. As is my wont, I looked for grasses along the way. There were lots of zoysia lawns where I started.

Even though high quality turfgrass can be produced below a soil pH of 5.5, for standard situations I will recommend keeping soil pH at 5.5 or above. Soluble aluminum will be negligible above pH 5.

Many of you will have seen the Kantarat Golf Course when flying into Bangkok. Maybe you’ve played it. It sits between the two runways at Don Mueang International Airport in Bangkok.

That was the title of my presentation today at the [Sustainable Turfgrass Management in Asia][1] conference. See the slides [here][2], or read the [handout for this presentation here][3].

Doug Soldat has photos showing more snow mold where potassium fertilizer was applied. Where potassium was not applied, there is less snow mold. This photo, starting in the top right plot with the lowest amount of snow mold, and going clockwise, is:

is now available, and I see from the Amazon.co.jp website that it can be shipped to any country. The full title is 芝草科学とグリーンキーピング (マイカの時間 The BOOK). In English that is Turfgrass Science and Greenkeeping (Micah no jikan The Book).

Steve Chappell shared these photos of snow and ice at Gleneagles, and I joked that it would be nice to play golf in such weather: For example, see Jim Prusa’s video of snow removal at SKY72 in Korea.

When I received an e-mail from Tom Sedlmeier a couple months ago, I was reminded of this update on the Sports Turf Solutions Facebook page in 2012: I just read a blog that puts every Turf Managers [sic] budget under scrutiny.

The recording of my webinar on preventing nutrient deficiencies is available in Spanish and in English. This was fun. I hope you’ll read the handout too. It is only 4 pages, with lots of white space, and gives a brief overview of this important topic.

This is nothing new. We’ve been discussing this for a long time. But these charts are new. I wanted to explain why I don’t worry about micronutrients. I’m going to explain this in words first, and show the charts at the very end.
