When a measure becomes a target, it ceases to be a good measure.
That’s a generalization of Goodhart’s law. I’m an advocate of measuring some surface performance, plant, and soil parameters.
I was talking with a golf course designer recently, and he mentioned that “zoysia starts to look pretty attractive because of its lower water use.” That led to a long conversation about how incorrect that statement is.
Yesterday I took a walk around a golf course in Chonburi, Thailand. It is three months into the dry season at this location; there has been negligible rainfall in Chonburi since the start of November.
The other day it rained at ATC南店. I knew that the grasses would grow at a faster rate after the rain than they had been growing prior to the rain.
One of the most interesting articles I read last year was Drought responses of above-ground and below-ground characteristics in warm-season turfgrass by Zhang et al. That article describes the drought response after 3 weeks with irrigation withheld:
There’s an interesting article by Zhang et al. about warm-season grass and what happened under water scarce conditions during 21 day dry down periods. This article, Drought responses of above-ground and below-ground characteristics in warm-season turfgrass, reports on an experiment in which bermudagrass (Cynodon dactylon), manilagrass (Zoysia matrella), Japanese lawngrass (Zoysia japonica), and St.
I’ve been asked about zoysia suitability for California, particularly northern parts of California, many times. Every time, I give the same answer. In such a relatively cool climate, and in such a relatively sunny and dry climate, Cynodon seems like a much better choice.
When I was at Keya GC last month for the Japan Amateur Championship, it rained a lot. From June 29 to July 8, there was precipitation every day, and the total was 446 mm, or 17.
Some years ago I shared some articles that I often referred to or recommended, and I called that Five articles every greenkeeper should read. As I look at this list of articles now, I’m reminded of the familiar maxim about understanding the rules before breaking them.
Every now and then I get some questions about the temperature-based growth potential (GP). The most recent question was about relative humidity:
“I am curious about the effect relative humidity has on growth potential?
