"Successfully complicating something that distracts us from the real challenges we should be addressing on golf courses"
Frank Rossi and Chris Tritabaugh had a short conversation about the fascinating Park Grass experiment, and about a lot more than that—fertilizer, bentgrass, dogma, salaries, budgets, detail work, GPS sprayers, and so on.

K fertilizer and more snow mold
Doug Soldat has been posting these spectacular photos every year. See the “related posts” section at the bottom for more of these from past years. When he shared this one, he wrote “stop me if you’ve heard this one before.

Pitch marks that last for days
This is a difficult problem—pitch mark scars—and the only long term solution I know of is firmer surfaces. I was reminded of that this week when I saw balls bouncing on the greens at a tournament in Japan (see videos below).

Tom Cook's extraordinary lawn
I was passing through Corvallis and stopped to meet Tom Cook, who maintains his primarily bentgrass lawn with the greatest of care. Or is it neglect? He has not applied fertilizer to the lawn in 15 years, irrigates during the summer dry period only enough to keep the grass green, mows weekly, hand pulls the most egregious weeds, interseeds with white clover, and even keeps an unirrigated strip of turf in which one can find rat’s-tail fescue (Vulpia myuros).

The art of Japanese golf course turf maintenance
There’s a short video about greenkeeper Mamoru Shoji and course maintenance at Kasumigaseki CC on YouTube. I especially like the view from the drone just after the 3 minute mark, showing the greens nestled among the carefully trimmed pine trees.

What We Talk About When We Talk About Disturbance
When I think about disturbance, I think primarily of verticutting and hollow-tine coring and sand topdressing and then brushing that sand in. Such an approach—one with disturbance—requires a faster growth rate too, and higher nutrient inputs, in order to recover from the disturbance.

Growing bentgrass in tropical heat
Bentgrass grows more—or at least it produces more clippings for a while—when temperatures are higher than optimum for net photosynthesis. This means that you’ll typically see more clippings when the temperature is above the optimum for cool-season grass, even though the growth potential (GP) goes down at those high temperatures.

No core aeration, no deep verticutting, and surprise! No summer decline
Perspective. It’s funny how that works. When I first read this research report in 2011, I skimmed over some parts, and cherry-picked what I was looking for — that 15 to 20% surface area removal was required every year in order to keep soil organic matter under control.

A "new" column, starting with creeping bentgrass heat stress
There’s a new column on the Nichino Ryokka website. It’s a collaboration between ATC and Nichino Ryokka, with some selected content from the ATC site published in Japanese. The first column is here, and the topic is a 12 point checklist for dealing with creeping bentgrass heat stress (the original list is here).
