I went for a walk in a park yesterday. In the first 30 meters, I saw four grasses. These are common grasses to find in parks in Southeast Asia. I took a photo of each grass from above, with a 1 yen coin as a size reference, and also a photo of the typical inflorescence of each species.

Turfgrass growth is affected by temperature. The temperature-based turfgrass growth potential (GP) is an easy way to look at how the actual temperature is related to the optimum temperatures for growth.

Not everyone understands how the MLSN guidelines work. I saw a photo shared by Andrew McDaniel followed by a number of replies from STSAsia exhibiting confusion on the latter’s part about the use of the MLSN guidelines.

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.
