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.
Books
My books about greenkeeping, turfgrass science, clipping volume, and MLSN.
MLSN
Minimum levels for sustainable nutrition—MLSN—is a modern method for interpreting soil tests for turfgrass.
Testing MLSN
I listened to Joe Gulotti’s Talking Greenkeeper podcast with guest Daniel Palin about an MLSN trial on 9 holes, and a different method on the other 9 holes. You can listen to the show for the full story.

Nutrient harvest turf math
A correspondent wrote with this inquiry related to estimating the value “a” in the MLSN fertilizer rate equation.1 Specifically, the “a” value is the expected plant use of the element over the time period for which the fertilizer recommendation is being made.

'Greenkeepers know, the world over, that if the grass grows too slow, they will be out of a job'
I was a guest on The Tie podcast where I spoke with Walker Simas about “Turf for Dummies.” Well, not quite to that extreme. We still managed to cover a lot of greenkeeping topics, but perhaps I explained the topics in a less technical way.

MLSN is not GP, and GP is not MLSN
I know this can use more explanation, because I’ve heard people refer to “their MLSN N” as being some amount. When I first heard that, I was taken aback, because nitrogen (N) is explicitly not part of MLSN.

Quantitative vs. qualitative: a little goes a long way
This is one of those blog posts that I finally can move from the list of notes about what I might write about, to the published and completed section. > [2020-08-29 Sat] On my run this morning from […] to […] I was thinking that a little bit of quantitative like OM246, knowing nutrient supply, clipvol, it goes a long way in leading to improved turf conditions.
