Finnish Greenkeepers Association, November 2 & 3, 2023

I used three sets of slides at this conference. You can download them at these links.

• MLSN: modern turfgrass nutrition
• Clipping volume, GP, and nitrogen
• OM246, organic matter/material, & sand topdressing

See more about OM246 testing, including sampling instructions and a sample report, at the OM246 project page.

You can get new information from ATC through our email newsletters.

I mentioned Chris Tritabaugh’s Substack newsletter. You can read it, and get a free subscription, at The ct_turf newsletter.

I mentioned the MLSN cheat sheet having information about converting between soil test methods other than Mehlich 3.

We also discussed some soil testing methods, and the scoop sizes for soil testing.

This 35 second video shows the 2 g scoop and the small crucibles used for soil organic matter testing.

This video takes a 22 minutes tour through the Brookside soils lab, and you can see some of the scoops, testing robots, and see all the steps of routine soil nutrient analysis.
