The ATC Doublecut with Micah Woods

I discuss ATC blog posts, with supplementary information, stories, and the reasons why I thought the topic was worth writing about, and worth reading about. Thus, a doublecut of these topics. This covers grass selection, playability, and all the work done to create a certain type of turfgrass surface.

ATC Office Hours

I discuss technical turfgrass topics with turfgrass managers, scientists, greenkeepers, and whoever drops by the ATC office hours. There's a lot of talk about the work done to create playing surfaces for golf, and also about growing grass for sporting surfaces of all sort, and also some talk of lawns.

Turf Without Borders

When I visit golf courses, I ask a standard series of questions about grass types, mowing heights, maintenance work, and site-specific maintenance challenges. In this show, I speak with turfgrass managers around the world, asking them the same questions about the work at their location.

When the soil report is not really about extractable vs. available nutrients

The topic of nutrient availability and extractable vs. exchangeable vs. available nutrients used to come up a lot, and I'm glad I haven't been asked this question as frequently in recent years. Fortunately, I have a long list of blog posts about this topic, and a good starting point is the one reviewed in this episode : https://www.asianturfgrass.com/post/its-not-really-about-extractable-or-available/ Read more about all kinds of turfgrass topics at https://www.asianturfgrass.com/Find a suite of decision-making tools at https://www.paceturf.org/Get free ATC newsletters at https://www.asianturfgrass.com/newsletter/

What happens to sand particle sizes after topdressing

I looked at sand particle sizes at the top of putting green rootzones, and compared those particle sizes to what is in the sand topdressing. The average results of this analysis are presented in this episode.

Wet air, summer, and dew point depression

I looked at the temperatures and dew points for a range of cities around the world during the first month of the most recent meteorological summer. June 2026 in the northern hemisphere, and December 2025 in the southern. The blog post discussed is: https://www.asianturfgrass.com/post/first-month-of-summer-dew-point-depression/ Also see the day in that month with the highest average dew point: https://www.paceturf.org/gallery/detail/first-month-of-summer-2026-maximum-dew-point Read more about all kinds of turfgrass topics at https://www.asianturfgrass.com/Find a suite of decision-making tools at https://www.paceturf.org/Get free ATC newsletters at https://www.asianturfgrass.com/newsletter/

Putting green firmness and surface organic material (OM246)

The firmness of putting greens varies with the surface organic material. More organic material in the top 2 cm (0.8 inches), and greens are softer. I discuss terminology, the relationship between firmness and organic material, and what you can do about this.
