Join me, along with Chris Tritabaugh from Hazeltine National GC, as we review autumn soil test results. We especially look at the #OM246 total organic material results, and discuss those in the context of maintenance work done, changes in the test results from past years, and most importantly, the relation of the tests to putting green performance.This video shows how to measure sand amounts: https://youtu.be/6LurONpyg5M?si=Von0kewt3gzi4wmeThis OM246 calculator finds the OM accumulation rate: https://asianturfgrass.shinyapps.io/om246/Find the climate appraisal form and more about GP at https://www.paceturf.org/Sign up for ATC newsletters at https://www.asianturfgrass.com/newsletter/About textbook N rates https://www.asianturfgrass.com/post/i-was-surprised-to-read-this-about-nitrogen-coring-and-sand/Summer cultivation and summer bentgrass decline https://www.asianturfgrass.com/post/hollow-tine-solid-tine-both-fail-alleviate-summer-bentgrass-decline/
