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:

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:

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.

Jason Haines wrote this:

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.
