Monthly Turfgrass Roundup: August 2018
Topdressing, more about topdressing, all kinds of videos, growth rates, wetting agents, tournament golf & superintendent recognition, history, one wish, and a lot more
After torrential rain, does all the potassium leach?
Doug Karcher has the best wetting agent photos.
It’s fun to evaluate wetting agent trials in late summer. No plot plan needed to pick out untreated controls. pic.twitter.com/2IqmOho1TJ— Doug Karcher (@uarkturf) August 28, 2018
Becky Grubbs showed some grasses establish fast and some grow slow:
The low-input NTEP trial that @reagan_hejl put in is coming along nicely. Always neat to see the differences in establishment rates across different species. Big differences here between bermuda, zoysia, and native turfgrass varieties. pic.twitter.com/oTvHfY9veX— Becky Grubbs-Bowling, PhD (@TXWaterWoman) August 8, 2018
A turfhack to find the soil temperature without actually measuring it.
Jon Wall went to Painswick.

18 holes of suspended terror set in the sky: Lost ball or 6 feet from the pin? You're never quite sure.
10 (!) hole crossings, blindness and Par 3's played into a bronze age fort. Unique. pic.twitter.com/skZD2GSVPs
T-Jay Creamer and J. Paul Robertson sat down between two bunker rakes.
Some turf history—C.V. Piper, orchids, & Pebble Beach.
Joel Kachmarek wrote a fascinating post about an irrigation system’s history.
Bill Kreuser has more advice about soil test interpretations.
Jacob Fuehrer and Bill Kreuser take a look at how much growth is enough.
HKT48 were back for another performance on the 18th green at the KBC Augusta golf tournament in Japan.
More about Japan golf, from the KBC archives, check out the gallery in this video from 45 years ago. The automatic translation says “A gallery flooded with green as if it were a lawless area!”

Tom Calder getting good results in efficiency and in favoring bent over Poa using ClipVol and MLSN:
I'd say still a way to go to get down to #MLSN levels, emptying boxes after 2 to 3 greens. Greens performing as well as ever, will be less than 2#/1000ft2 N this season. Poa weak and bent taking over. Also 0# of anything to fairways in 3 years bent very happy. @asianturfgrass pic.twitter.com/9i4NIrEGoS— Tom Calder (@tomosocanoso) August 9, 2018
Wang et al. wrote about research at Rutgers showing the season of topdressing application influences anthracnose of Poa annua. From the abstract: “Golf turf managers should recognize that autumn topdressing will aid in anthracnose suppression; however, spring applications are more effective when anthracnose is the management objective.”
The Hamilton GC Course Maintenance blog had a post about decreasing organic matter without coring.
Carl Schimenti and I had various discussions about ball reaction on greens:
Yesterday @Carl_Schimenti asked about ball reaction when landing on the green. This and the next video are mid to short irons from the fairway on a flat shot with negligible wind. pic.twitter.com/b6jFPuEAqu— Micah Woods (@asianturfgrass) August 23, 2018
Bier et al. wrote this article showing more than enough K was supplied to bentgrass from topdressing sand, with no supplemental K required as fertilizer.

The one thing I wish all golfers would understand is that greenkeepers do the best they can EVERY DAY with the resources, weather, and circumstances they are dealt. We NEVER come in and say "just half ass it today guys"— Jason Haines (@PenderSuper) August 27, 2018
John Reitman wrote about Tom Samples and his great advice about lifelong learning.
Schlossberg et al. wrote about the important reduction in NH3 losses achieved by treating urea fertilizer with urease-inhibiting additives.
