It’s got the current guidelines, along with sections including: how to use MLSN an MLSN calculator reference documents case studies further reading If you have any questions about MLSN, you are likely to find the answers on the guidelines page.

A correspondent wrote with a question about firmness and compaction, about managing the balance between them, and whether there is a difference when analyzing a rootzone. Bouncing a ball on a green with excellent firmness, but what about compaction?

When you apply topdressing sand to a golf course putting green, you might reasonably expect that the particle sizes of that topdressing material will eventually be the particle size you’ll find in the rootzone.

Frank and I talked about some of the things we studied and learned when I was a graduate student, and we talked about what we are doing today. I had a good talk with Dr.

Here are two podcasts you may want to put in your listening queue. They’ve got a nice balance of topics, especially compared to the technical and narrow topics I sometimes focus on.

There are a lot of factors involved with managing the firmness of turfgrass surfaces. I’ve been making a lot of measurements of firmness recently—actually I’ve been measuring this for a long time, come to think of it—and I share some of my recent observations in two PACE Turf updates and in this video.

I was discussing saturated paste test results and made an offhand comment about the ease of using saturated paste data to demonstrate how calcium (Ca) is so abundant in the soil that it accumulates around the roots.

I’ve been making great use of the PACE Turf search function, and I am sure you will too. A recent search for black layer turned up 52 results including 13 images.

As we have done for each KBC Augusta Tournament we’ve worked together, Andrew McDaniel and I went to Natty Dread for lunch at the start of the week. This year the tournament will be played on greens that haven’t been sand topdressed for fourteen months—the last topdressing was early summer of 2025.
