MLSN

Soil tests

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.

MLSN

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

Simple solutions to a difficult problem

When Bernd Leinauer introduced me prior to this talk, he mentioned that I’m one of the most controversial turfgrass scientists today. And the reason for being controversial happens to be the very topic of this presentation1 that I’ve uploaded today to my YouTube channel.

MLSN and turfgrass nutrient recommendations

GCM Magazine has another article about the SLAN and MLSN methods for soil test interpretation. The article summarizes Jackie Guevara’s research (with Kevin Frank at Michigan State University) into turfgrass response when P and K applications are made based on MLSN.

Lack of response to a fertilizer application

These pots of variegated tropical carpetgrass (Axonopus compressus) received an application of granular 16-16-16 fertilizer twelve days before this photo was taken. The grass on the right responded with a lot more growth than did the grass at left.

Extending the beer analogy

I’ve explained how MLSN works by telling a story about beer. Specifically, about a natural and logical method to figure out how many beers to buy at the store prior to an upcoming party.

What you answered about MLSN

In the 14th MLSN newsletter, I asked what would you like to see, hear, learn, or know about MLSN? I summarized the results of that survey in the chart above.

Soil test showdown

A recent PACE Turf update mentioned this research project by Jackie Guevara and Kevin Frank: Effects of different soil testing interpretation philosophies on creeping bentgrass and annual bluegrass putting greens.
