Joe Gulotti’s The Talking Greenkeeper podcast is popular all over the world. When I travel, I often meet people who tell me how much they enjoy listening to his show, and some who tell me they first heard of me, or of MLSN, by listening to the show.

Chris Tritabaugh has completed his series of blog posts about playability, organic matter management, change, and consistency, with one titled What we do. The series started with Is that disruption?

I’ve been doing some of the updates since spring, and all of them since mid-summer, and I list—below—all the 125 PACE Turf updates so far this year to show you the range of material covered.

I’ve tried to explain the value of total organic material testing by comparing it to the soil organic matter. In the timelines shown below, the total organic material in the top 2 cm (0.

Some videos on the ATC YouTube channel have chapters—timestamps—that I have added for different topics. I haven’t done that for all the videos, but it is really cool that YouTube has identified some of the topics and added the timestamps automatically.

I spent a couple hours today collecting total organic material (OM246) samples and soil nutrient samples. When this Tifeagle bermudagrass green was tested for total organic material twelve months ago, the OM2 (total organic material in the top 2 cm) was 11.

Have you heard about the Park Grass experiment? The one that started in 1856 with different fertilizer treatments applied to a hay meadow in England, with those fertilizer treatments applied year after year to see what happened to hay yields?

This topic—carbon in turfgrass soils—was the subject of a Frankly Speaking podcast episode. One of the topics host Frank Rossi spoke about with guests Drs. Claire Phillips and Alec Kowalewski was the nitrogen mineralized from soil organic matter.

First some background information. I had shared this post that showed a number of different scenarios of organic matter change with hollow-tine cultivation (coring) and solid-tine cultivation, including examples with and without sand topdressing.

I recommend annual soil testing of professionally-managed turfgrass grown on sand rootzones. For turf growing in soil, I don’t mind testing every two or three years. But sand rootzones usually aren’t very well buffered and important soil properties can change rapidly.
