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 asked a question in the MLSN newsletter1 — when getting a recommendation for nutrients, would it make more sense to have that recommendation expressed as a ratio or as a percentage?

This is how I think everyone should do it. Make nutrient applications that have a site-specific ratio of nitrogen (N), phosphorus (P), and potassium (K). I write this because I’ve had some questions about ratios and about fertilizer nutrient analysis, and I want to explain this in a general way.

I was in Hua Hin for two days of shooting with Mattias Brännholm of Brama. We were discussing MLSN, which I described as a modern way to make fertilizer recommendations for turfgrass.

One of my favorite publications is the The Greenkeeper annual yearbook by Ikki Publishing Company. This yearbook includes annual maintenance summaries for golf courses in Japan. This is a type of practical information that I find really useful.

Joe Hollier wrote to me a few weeks ago asking if I could write something about MLSN for the STANZ newsletter. I sent this quick reply: Gosh, this is the kind of thing I should say no to because I’m quite busy and don’t want to add more things to do to my list.
