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.

Remember, the OM246 test measures the total organic material, living and dead. A 4 cm diameter core of fine-bladed manilagrass with extensive living plant material below the surface. If the grass has a more extensive root system, or a more extensive rhizome system, the OM value measured on an OM246 test will go up simply from there being more total organic material in the sample.

Predicting, checking, and adjusting growth rate with clipping volume and growth potential I’ve discussed clipping volume and growth potential at events across Canada over the past eight years. For a review of that material, see:

Many of you will have heard the announcement from Joe Gulotti that The Talking Greenkeeper is on hiatus. A lot of us enjoyed hearing from Joe and his guests almost every week, and we are going to miss it.

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.
