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.

I went to Sydney, Adelaide, and Brisbane to discuss the MLSN approach to soil test interpretation in four seminars organized by Living Turf. In these seminars, I explained that the use of the MLSN guidelines is as simple as planning how many beers to buy for an upcoming party.

I taught two seminars at the 2017 Philippine Golf Course Management conference. One was about MLSN after 5 years. I explained what soil test interpretation is, why the MLSN guidelines were developed, and explained how they work.

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.

Doug Soldat has photos showing more snow mold where potassium fertilizer was applied. Where potassium was not applied, there is less snow mold. This photo, starting in the top right plot with the lowest amount of snow mold, and going clockwise, is:

When I received an e-mail from Tom Sedlmeier a couple months ago, I was reminded of this update on the Sports Turf Solutions Facebook page in 2012: I just read a blog that puts every Turf Managers [sic] budget under scrutiny.

The recording of my webinar on preventing nutrient deficiencies is available in Spanish and in English. This was fun. I hope you’ll read the handout too. It is only 4 pages, with lots of white space, and gives a brief overview of this important topic.

This is nothing new. We’ve been discussing this for a long time. But these charts are new. I wanted to explain why I don’t worry about micronutrients. I’m going to explain this in words first, and show the charts at the very end.

Ryan Goss made a good point in the discussion about how much fertilizer is applied on golf courses.1 There are two basic scenarios. The first scenario is no soil testing, in which it makes sense to apply the same amount of fertilizer, $F$, as the grass can use, $G$.

That arrived in my inbox recently, plus a few questions about calculating K requirements using the MLSN guidelines, and whether if there are minimum levels, are there optimum levels too? Here’s how I answered.
