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.
Golf turf playability with Carl Schimenti: green speed, firmness, smoothness and trueness of roll
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.
No change in soil OM after sand topdressing just once in a year, with Andrew McDaniel
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.
Leaf nutrient analyses (tissue tests) with Doug Soldat
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.
Chris Tritabaugh's blog, disruption, and playability
Chris Tritabaugh joined me to discuss his recent blog posts about what putting green disruption is, and how he has been working to minimize it through measurement of green speed and green smoothness and trueness.
Turfgrass growth potential (GP) with Larry Stowell from PACE Turf
Larry Stowell joined me to discuss the temperature-based turfgrass growth potential --- where it comes from and how it is used. We also discussed a bit about MLSN and the interaction of GP with MLSN.
Nutrient requirements of Poa annua and MLSN with Ben Brace
Ben Brace and I discussed how we expect MLSN to work for Poa annua, and if there might be some differences compared with creeping bentgrass. We discussed biostimulants, soil sampling, potassium and stress, phosphorus and bentgrass vs. Poa competition, and much more.
