Last year I wrote about a soil temperature turfhack. The soil temperature is almost always between the day’s high and low temperature. The soil temperature at a 5 cm depth immediately after planting manilagrass stolons on 22 April.

In the ATC update sent earlier this week—subscribe here if you’d like to get on this list—I mentioned that one of the highlights of my year so far was the Royal Turf Family Seminar at the Park Hyatt Tokyo.

I put the series of genki level (GL) blog posts together into this 17 page pamphlet. The pamphlet explains how one can calculate the genki level from the actual N supplied as fertilizer compared to a standard amount of N for any time duration.

Mike Richardson shared an image of aerifying half a green at a time. The purpose of this, the superintendent said, was to always have a good surface for the hole.

Andrew McDaniel asked me if day length or temperature has a bigger effect on zoysiagrass going into or coming out of dormancy. I hadn’t really thought about that before. When I did think about it, I realized I pretty much only think of temperature, but I wondered if living in a tropical location where the grass doesn’t go dormant might be blinding me to something that happens where day length varies.

I made a note a couple months ago to make animated charts showing the cool-season (C3) and warm-season (C4) turfgrass growth potential over a 100+ year period for Tokyo. I was interested to see what those charts would look like.

A correspondent wrote with this inquiry: “As discussed a question regarding how soil tests work. Do the various soil tests only test for readily soluble nutrients in a given soil sample, for example the ions within the capillary stored soil moisture?

There’s an interesting blog post by Jim Orson titled “Read this before leaf tissue testing for micronutrients.” The entire post is worth reading. It describes his conclusions after studying the result of 15 trials with winter wheat.

Or at least they had a captivating discussion on The Talking Greenkeeper show. They talked about a lot of things: name dropping manga taking shoes off, or not doing things or applying products for a reason what it was like to work for Micah Woods what it’s like to now be assistant GM in addition to head greenkeeper baseball greenkeeping in Japan much more I hope you enjoy this episode of The Talking Greenkeeper as much as I did.

A correspondent wrote with a question about soil biology for controlling organics, adding compost tea to feed beneficial bacteria, and etc. There are two articles that I recommend as an introduction to this topic, both by David Zuberer.
