OM246

We provide soil testing services for clients around the world through Brookside Labs, and have an active research program in the area of turfgrass nutrition, soil and plant analysis, and sampling methods.

Measure exact topdressing effect, and requirement, by checking total organic material by depth.

I’ve updated the OM246 calculator to v2 with two substantial changes. One is an entirely new tab for unit conversions between different ways of expressing sand rates. I like mm. Others use kg/ha or tons/ha.

When you do OM246 testing to find the total organic material at known depths of the rootzone, you can use those test results to find the net accumulation rate of organic material in the rootzone.

I’ve been listening to Joe Gulotti’s The Talking Greenkeeper since the first episode back in 2018. I’m sure many of you listen to his show as well. We’ve heard Joe talk about the turf on the Montchanin course that he manages.

One of the many ways to learn is through conversations with industry veterans. Their wisdom about how turf is managed now, and how it was managed in the past, can be invaluable.

You may be familiar with the grammar of greenkeeping. That’s what I call the approach to turfgrass maintenance that focuses on growth rate. As I wrote in the preface to the book with that title:

I prepared a new video about OM246. This video premiered at the Ontario Turfgrass Symposium last week, and it’s now available for worldwide viewing. I wasn’t able to get to Ontario for this event, but I was glad to have the opportunity to explain why OM246 testing is done, how it works, and what one can do with the results.

I was a guest on The Tie podcast where I spoke with Walker Simas about “Turf for Dummies.” Well, not quite to that extreme. We still managed to cover a lot of greenkeeping topics, but perhaps I explained the topics in a less technical way.

I was collecting OM246 samples at sunrise on a busy golf course near Bangkok on Tuesday, and I remembered that I was going to update the OM246 sampling instructions. That update is now made, so when you download the sampling instructions, you’ll get version 0.
