The ATC Doublecut with Micah Woods

Andrew McDaniel ( https://twitter.com/drumcturf ) joined me as a special guest on this episode to talk about the extra hole at Kawana's Fuji Course ( https://www.asianturfgrass.com/post/best-extra-hole-in-golf/ ) and about tropical turf management at Nikanti GC in Thailand with #MLSN, #ClipVol, and #OM246 ( https://www.asianturfgrass.com/post/all-the-hashtags-in-a-tropical-climate/ ) Watch this ep...

It is easy to know when grass grows too slow: https://www.asianturfgrass.com/post/dangerous-grow-too-slow/ Tom Cook's extraordinary lawn (blog post): https://www.asianturfgrass.com/post/tom-cooks-extraordinary-lawn/ Tom Cook lawn tour video: https://youtu.be/mcCxYVSIc5k Flying Blind video with David Bataller: https://youtu.be/n8Ir2lVnGyE Watch this episode on YouTube: https://youtu.be/iNNvOvnT_PE...

This is an obvious concept but the implications are complex. If soil organic matter accumulates more rapidly in young soils, and if one wants to manage soil organic matter most efficiently, then it makes sense to keep the soils in an older, rather than in a younger, state. Soil age and OM accumulation rate: https://www.asianturfgrass.com/post/organic-material-accumulates-faster-when-soil-om-is-low...

I discuss my visit to (and seminar at) the University of Florida, and consider whether soil organic matter content stability over time might be related to the inherent accumulation rate of said organic matter. My visit to University of Florida: https://www.asianturfgrass.com/post/seminar-and-visit-at-university-of-florida/ My recorded seminar screencast from University of Florida: https://youtu.be...

I discuss two presentations from the ATPI conference in Galway, Ireland, how one might think about soil "deficiencies" when doing soil test interpretation, and discuss my tissue testing manifesto. Recorded Ireland conference presentations: https://www.asianturfgrass.com/post/soil-grass-and-playability/ Tissue testing manifesto: https://www.asianturfgrass.com/post/tissue-test-manifesto/ MLSN and co...

I discuss tests for soil organic matter, and explain the distinction between those tests and a different kind of test for total organic material by depth. I also talked briefly about a new MLSN film. I discussed the "A Tale of Two Tests" blog post which describes the value of measuring soil organic matter (SOM) and also measuring total organic material by depth (#OM246): https://www.asianturfgrass...

This discusses how changing the variance value in the turfgrass growth potential equation will change the shape of the curve as one moves away from the optimum growth temperatures.  PACE Turf: https://www.paceturf.org/   Climate appraisal forms with GP equations included: https://www.paceturf.org/index.php/journal/climate   Watch this episode at: https://youtu.be/HBquDPySSto ATC Office Hours with...

I discussed using the temperature-based growth potential (GP) to make comparisons between locations.

I discuss the 7 question, 2 minute survey, about soil sampling procedures for turfgrass, and I explain why this is an important topic that I've been paying more attention to. I discuss a survey I conducted about how soil samples are typically collected prior to sending to a laboratory for analysis. I discussed these blog posts that show the background and the full survey results: https://www.asian...

This is about #MLSN and about the precision fertilisation approach developed by Tom Ericsson. The post I discussed is at: https://www.asianturfgrass.com/post/2-similar-approaches-to-fertilization-with-1-notable-difference/ The clip of John Jacob and Joe Gulotti is from this episode of the Talking Greenkeeper podcast: https://podcasts.apple.com/us/podcast/the-talking-greenkeeper/id1435947281?i=1000...

I gave a detailed answer to 5 comments about this Office Hours episode ( https://youtu.be/J5_5mDJ-Vxc ) about OM246 testing.

I showed photos from a post on zoysia, water use, and fact checking, to show that when irrigation is restricted, and it doesn't rain---drought conditions---zoysia needs more water than bermuda to stay green and growing.

This episode is a discussion of this blog post and article: https://www.asianturfgrass.com/post/one-thing-i-wish-everyone-understood-about-mlsn/ Grass uses nutrients, so we can expect the soil nutrient level to be lower tomorrow than it is today. By making a prediction of the decline in soil nutrient levels for a specific time duration, one can come up with a fertilizer recommendation that ensures...
