Zoysia

You may have seen a few posts about #rturf on my personal site. I’m writing about that topic over there so I don’t clutter up the ATC site with too much data analysis and computer code.

Have you ever seen patches like this on Zoysia turf? Maybe the early stages of an intense large patch outbreak, or elephant’s footprint (Rhizoctonia cerealis) that got out of control? Way out of control?

When I play golf, I much prefer to walk, so the choice between walking and riding is usually an easy one. These all-terrain vehicles are staged near the first tee, ready for action.

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.

When I saw how these grasses were growing at #ATC南店, I jotted down a couple notes for a future blog post—this one. when grass grows more, it makes more roots

The N-only pot looked pretty good when I showed roots after 184 days. But that same grass grew a lot more, and produced a lot more underground roots and rhizomes, when P and K were added.

Regular readers of this site will remember the grow-in experiment I started on 1 October 2019. I wrote about it in these posts. Fertilizer response at planting Experiment update: fertilizer response at planting

This photo was taken 174 days after the ‘Tifeagle’ bermudagrass and ‘Wana’ manilagrass were planted as 3 cm diameter plugs on 1 October 2019. These particular pots have been fertilized with nitrogen only since then, with no P or K.

I was in Fukuoka last weekend and enjoyed the mid-winter weather and the seasonal colors of the turf. This is what golf courses in Japan look like in the winter.

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.
