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.

These questions came by email. After watching the ATC Office Hours autumn 2022 OM246 review (and other ATC content) I had a few questions. I have researched and studied two specific items but couldn’t find the exact answer to what I was looking for.

I use the turfgrass growth potential (GP) all the time. I make use of the GP for all kinds of things, like predicting sand topdressing amounts, comparing locations, predicting nutrient use, checking overseeding dates, estimating mowing requirements, and many more.

After I wrote this post about the differences in P fertilizer recommendations when using different methods for soil test interpretation, I heard from some readers that it seemed I was taking something simple—MLSN—and making it seem complicated.

On November 2 & 3, I’ll be at the Portuguese Greenkeepers Conference in Porto. You can register for the conference at the APG website. Here are three quick notes. 1. The five exciting topics I’ll be discussing I’m going to lead a series of short seminars at the conference.

Daniel Hahn and Romain Giraud wrote an article on LinkedIn about fertilisation decisions based on MLSN and STERF’s precision fertilisation (SPF). If you are at all interested in this topic, I hope you’ll read their article.

I gave two presentations, about two of my favorite topics, at the Golf Matters NZ Conference in Christchurch. Links to the recorded screencasts are below, if you’d like to get the entire presentation in rapid form.

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?
