Fertilizer supply vs. nutrient use
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.

One thing I'd like everyone to understand about MLSN
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.

Adding potassium fertilizer does not increase the soil's ability to store it
You’ve probably listened to one of my seminars in which I explained why conventional nutrient guidelines for turfgrass are broken. Jackie Guevara’s thesis on “Effects of Different Soil Testing Philosophies on Creeping Bentgrass and Annual Bluegrass Putting Greens” is an excellent demonstration of this.

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.

Tissue tests as "postmortem types of analyses"
Soil nutrient analyses—soil tests—are used to determine if certain elements are required as fertilizer. If an element is required as fertilizer, the soil test will be interpreted to make a recommendation for the quantity of the element required.

N input accounting
Phil Collinson asked an interesting question: when calculating N inputs, do greenkeepers account for N added outside of fertilizer? Greenkeepers - when calculating N inputs for the year do you account for N outside of fert?

Fun on my front steps
On February 28, I took Wana—a fine-bladed putting green type manilagrass—rhizomes and cut to a two node length. Then I planted these cut rhizomes, each with two tiny plants on them, in the center of sand-filled pots.
