ATC Office Hours

Jason and Bjarni joined me to talk about some useful turfgrass math, especially the turfgrass growth ratio, which you can read more about at https://www.asianturfgrass.com/tag/growth-ratio/Find more infomation at PACE Turf: https://www.paceturf.org/ And at the ATC website: https://www.asianturfgrass.com/

For the third consecutive autumn, Chris Tritabaugh joined me to review the OM246 (total organic material by depth) test results from the greens at Hazeltine National Golf Club. We discussed playing conditions, maintenance work, and testing.Here are some links.Chris's Substack: https://ctunderscoreturf.substack.com?utm_source=navbar&utm_medium=web&r=dakt8ATC website: https:/

Richard Forsyth is the director of courses at Royal Melbourne Golf Club. We discussed playing conditions, maintenance work, and grass types in relation to production of firm putting surfaces.Chris Tritabaugh and Doug Soldat also spoke about putting green firmness in this podcast: https://open.substack.com/pub/ctunderscoreturf/p/doug-soldatA note about soil surfactants: https://www.

Eric Johnson joined from his office at Chambers Bay to discuss everyday golfing conditions, championship playing surfaces, and workflow using techniques such as clipping volume (#ClipVol), total organic material testing by depth (#OM246), and nutrient supply using #MLSN.You can find Eric on Twitter at https://twitter.com/altshot2Read more about all kinds of turfgrass topics at http

Dr. Roch Gaussoin, professor at the University of Nebraska-Lincoln, joined me to discuss cultivation of golf course turf, sand topdressing, soil organic matter testing, and the topic of soil organic matter/material management in general.

Total organic material testing (OM246) can be used to calibrate the amount of sand and cultivation required to produce high performance putting surfaces. Chris Tritabaugh and I discussed the most recent results from tests conducted at Hazeltine National Golf Club.

Jackie Guevara did an experiment that compared no P or K fertilizer, those elements as recommended by MLSN, and those elements as recommended by SLAN. The results? MLSN and SLAN were both better than nothing. But MLSN used a lot less fertilizer.

Carl is a competitive golfer and a turfgrass researcher. We had a long conversation about the topic of playability of surfaces. What is it, how is it measured, can it be measured, and how might it be managed.

Total organic material by depth (#OM246) measurements have been made at Keya GC for six years. We discussed these results and how the organic matter has remained constant over time despite minimal sand topdressing and only 1 hollow-tine aerification in six years.

Doug Soldat joined me to discuss tissue tests for turfgrass, and how we might make use of them (or not) to make decisions about fertilizer.
