This episode introduces ΔGP, which is cool-season grass growth potential minus warm-season growth potential. Too many days like that and you won't bother trying to grow cool-season grass anymore. Also, best time of the year to soil sample, a superb podcast from Chris Tritabaugh, and a careful look at the difference between soil organic matter and total organic material. These posts were discussed:Delta GP and summer of 2022: https://www.asianturfgrass.com/post/last-summer-at-36-locations/Best time to soil sample: https://www.asianturfgrass.com/post/best-time-of-year-to-soil-sample/Tritabaugh, Rossi, and Park Grass: https://www.asianturfgrass.com/post/distracting-us-from-the-real-challenges/All about OM246 testing and the different procedures at the lab: https://www.asianturfgrass.com/post/all-about-om246/See the ATC newsletters at https://subscribepage.com/atc_newslettersRead more about all kinds of turfgrass topics at https://www.asianturfgrass.com/Find turfgrass information and decision-making tools at https://www.paceturf.org/See the PACE Turf YouTube channel at https://www.youtube.com/user/paceturfListen to the ATC Doublecut with Micah Woods podcast at https://atc-doublecut.transistor.fm/Listen to the ATC Office Hours podcast at https://atc-office-hours.transistor.fm/ More about ATC soil tests at https://www.asianturfgrass.com/project/soil-tests/
