MLSN

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.

My books about greenkeeping, turfgrass science, clipping volume, and MLSN.

Minimum levels for sustainable nutrition—MLSN—is a modern method for interpreting soil tests for turfgrass.

I was a guest on the USGA Green Section podcast for an episode with the title Hot Takes on Turf with Dr. Micah Woods. Host John Petrovsky asked a range of questions that I found quite interesting, and I hope you will too.

Joe Gulotti asked me back to The Talking Greenkeeper studio this week for what he calls an “annual holiday extravaganza.” We had a holiday-worthy talk about MLSN, putting green smoothness, my acting skills, travel, and efficient greenkeeping.

I’ve been in a long and intermittent conversation with The Grass Factor team about a guest appearance on their show.1 It’s gone something like they invite me, I can’t due to schedule, then six months later they ask again, and I’ll be off on a long trip again, and I ask them to contact me again some months later.

When I make nutrient recommendations, I recommend a quantity of each element that ensures the grass can get all of that nutrient that the grass can use. I also make the recommendation with a thought about the soil.

A couple of the science and statistics blogs I follow have recently shared AI-generated audio summaries of research papers. The ones I’ve seen were from Google’s NotebookLM. I hadn’t been using this, with most of my LLM (large language model) use over the past couple years being ChatGPT.
