ATC Office Hours

Chris Tritabaugh and I share and comment on the latest #OM246 test results from what is now a time series stretching over the past seven growing seasons. We discuss what has changed, what hasn't, how surfaces perform, and how total organic material (TOM, or #OM246) data can be used to nudge surface conditions in the desired direction.

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: htt...

Jackie's thesis at Michigan State University was titled "Effects of Different Soil Testing Philosophies on Creeping Bentgrass and Annual Bluegrass Putting Greens." She looked at how much P and K were applied by different interpretation philosophies, how the grass stood up to traffic, and what happened to the elements that were applied.  All about #MLSN: https://www.asianturfgrass.com/mlsn/   Three...

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.

Chris Tritabaugh, the golf course superintendent at Hazeltine National Golf Club in Minnesota, discusses an OM246 report for samples collected in October 2021. This is total organic material by depth, and knowing the results of this test provide valuable information to optimize golf course playability while ensuring one is applying just the right amount of sand. For more about this, see the OM246...
