New MLSN cheat sheet

I thought it might be useful to summarize the key details of MLSN in a cheat sheet. For people using MLSN, or wanting to use it, this 2 page cheat sheet is intended to be a handy reference.

More than a success story

This isn’t just a story about the fertilizer choices or the costs. There is a lot more to it, and I encourage you to read the entire post at Gulotti’s The Walking Greenkeeper blog.

I've been asked to give a seminar on MLSN guidelines

This inquiry came to my inbox: “I’ve been asked to give a seminar on MLSN guidelines for the [ ]. I intend to keep the explanation fairly simple. Are there any frequently asked questions that you have encountered that I could use in my presentations to help me make sure I’m explaining it clear enough … On a side note…I have been teaching this method of soil fertility interpretations for two years to my [ ] turf students and I can’t quite understand the resistance I get from superintendents….

"Percent base saturation seems not to be a particularly useful concept"

I saw a list of proposed topics for an upcoming turfgrass conference, and under the heading of soil fertility was included base saturation. I immediately thought of this paragraph from Murray McBride’s Environmental Chemistry of Soils:

MLSN in use: soil tests, fertilizer, and the results

When Andrew McDaniel wrote about #MLSN greens, I thought it may be interesting to show a few details of what this is about: These #MLSN greens are about to take 34 mows/21 rolls in 2 weeks.

An economic case study

When my friend wrote to ask if I could “write a brief description of MLSN,” I thought I might send along the article on turfgrass fertilization from the Green Section Record by Meentemeyer and Whitlark.

No matter how much sodium one puts into a sand rootzone, the soil structure cannot be affected, so gypsum won’t be required

I received this question about leaching salts from the rootzone: “I remember talking to you once before regarding flushing excess salts from the root zone and the application of gypsum or other calcium products before the flush and you telling me it was not necessary.

Of turf, roots, and fertilizer

I’d like to make three points. 1- Surfaces can be great, and the roots can be negligible. If the objective of greenkeeping work is to produce the desired surface, then one only needs enough growth to produce that surface.

An MLSN Refresher

Not everyone understands how the MLSN guidelines work. I saw a photo shared by Andrew McDaniel followed by a number of replies from STSAsia exhibiting confusion on the latter’s part about the use of the MLSN guidelines.

Both of these are worth your time

One is an article, another is a podcast, and you won’t regret the time spent reading the first and listening to the second. First, the 4 November 2016 issue of the Green Section Record contains Managing Organic Matter in Putting Greens by Adam Moeller and Todd Lowe.
