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.

Does soil water content affect nighttime soil temperatures in summer?
I was wondering what the effect was. I expected a 1 or 2 °C decrease in nighttime soil temperature in drier soils, compared to soils with more water. I didn’t find it.

Comparing nutrient content of turfgrass soils
The MLSN guidelines were developed from a large dataset of soil tests collected from good-performing turf. You’re probably familiar with the MLSN guideline as a minimum level, with fertilizer recommended to make sure the soil doesn’t drop below the guideline.

How to save 82% on fertilizer cost
There is an extraordinary article in the Green Section Record by Blake Meentemeyer and Brian Whitlark on turfgrass fertilization. You’ll want to read the full article. It talks about the overall goals of fertilizer application, soil tests, some myth busting, fertilizer and playability, and more.

Bhupendra Singh posted a photo on Instagram with this caption: Growing roots! Tifdwarf at Peacock Course Greens, Delhi Golf Club I wondered how the grass had been managed for the past six months.

Is this the most common oxymoron in turf?
An oxymoron is a contradiction in terms, and the one about nutrients being present but not available, or exchangeable but not available, or adequate but limited, is one I hear again and again.

It’s not really about extractable or available
For a while, this topic was coming up every few months. Here’s an example from an e-mail inquiry. I paraphrase the words here, but keep the punctuation intact, and I omit course, company, and superintendent names:

Beware! These topics are misleading and irrelevant
In July 2015 I led a seminar entitled “A discussion mostly about the principles of turfgrass nutrition, with a focus on soil nutrient analyses and their use in modern turf management.

2 similar approaches to turfgrass nutrition, with 1 notable difference
At first appearance, the demand-driven fertilization of STERF seems almost the same as the growth potential (GP) and MLSN approach. If you are not familiar with this approach from STERF, you can download their Precision Fertilisation – from theory to practice handbook, written by Tom Ericsson, Karin Blombäck and Agnar Kvalbein.
