"I've waited far too long to voice my opinions concerning this extraordinary profession of greenkeeping"

How's that for a start? "The Walking Greenkeeper" introduced himself this morning. I expect this will be a fun blog to read.

Selection_010Now for an assortment of things that came to mind today, all of which are in some way related to Joe's blog post.

He wrote about some of his research this winter. Among other things, he mentioned me, MLSN, Jason Haines, and Chris Tritabaugh. "These fellas," he wrote, "and what I consider to be their alternative style to greenkeeping have inspired me ..." -- that's awesome.

So what came to mind? First, the #MLSN approach is about something very specific -- making fertilizer recommendations from soil tests to prevent nutrient deficiencies by ensuring the grass is supplied with enough of each element. However, the approach we have taken with MLSN has attracted interest from turf managers around the world who are interested in minimizing other inputs as well. And it is a lot of interest. I've been surprised that the MLSN newsletter mailing list, started just 6 weeks ago, already has more than 300 subscribers, from more than 30 countries.

If you are interested in the MLSN approach, you can subscribe to the newsletter here.

If you want more than just MLSN, you can sign up to the ATC newsletter here.

Here's an interesting question. Just what is the MLSN approach? Nadeem Zreikat wrote that he prefers efficient to minimalist:

Here's how I'd describe it. Lots of people are interested in MLSN and in the idea of managing things as efficiently as possible. I'd describe what I try to do, and with MLSN as a part of that, in this way:

For turf management at any site, the first thing to do is to define the conditions that one is trying to produce. Then, produce those conditions with the fewest possible inputs.

One could describe that as efficiency, or as minimalistic. I think both words, and many other words too, can fit the MLSN approach.

I wrote more about that in the Short Grammar of Greenkeeping. To produce the desired conditions, the turf manager manipulates the growth rate. In the Short Grammar, I wrote that greenkeeping can then be defined as modifying the growth rate to get the desired surface conditions. And the grammar provides a framework for adjusting the inputs to produce the desired conditions.

If that all sounds really vague, you'll want to read a great description of that approach in practice. I recommend Jason Haines' Turfhacker summary of everything that's interesting to me as a description of how these principles can be applied.

The whole idea is to produce the conditions we want, doing so with the minimum amount of work. Maybe that's efficiency, or minimalism, or sustainability, or something else. But that's where I'm coming from, that's the type of definition that the MLSN approach fits into, and this is for any type of turf.

I made a huge omission in last month's roundup. I forgot to include the 2016 Ryder Cup: Hazeltine National Turfgrass Team video featuring Chris Tritabaugh.

2016 Ryder Cup: Hazeltine National Golf Club, The Turfgrass Team from Chris Tritabaugh on Vimeo.

This is part of the approach too, and the video shows it. Be passionate about the work. Produce the conditions one is trying to produce. Do so with a minimum of inputs. Or as efficiently as possible. Have fun doing it. Find ways to do it better.

I expect everyone in this business is doing that in some way. It seems to me that the MLSN and Short Grammar approaches have provided a framework from which we can all work on and compare ways to do it better.

[10] November, Both of these are worth your time about organic matter management, and coring greens, or not.

[9] May, Roots, growth potential, and fertilizer discussing what was applied to putting greens in New Delhi.

[8] April, Is this the most common oxymoron in turf? about a question that just won't go away. Can nutrients be adequate but not available?

[7] November, Fall potassium and winter traffic on a bentgrass green about the remarkable tolerance of creeping bentgrass to traffic when frozen.

[6] October, Daily versus monthly calculations of ET and irrigation requirement in which I show that a daily soil water balance gives a totally different irrigation requirement than does a monthly calculation using the standard method.

[5] February, Which products and technologies are truly beneficial and cost-effective? is a quote from Dr. Carrow's Green Section Record article on Purchasing new products and technologies: an ethical and common-sense approach. He explains why this is an ethical issue, and gives 7 questions to ask about products and technologies.

[4] January, Knowing which soil test results are important can simplify turf management. That's a quote from Bill Kreuser; he says that "while soil tests can be useful, their results are frequently overanalyzed and overinterpreted."

[3] September, Fast release fertilizer, fertilizer burn, and root growth in which those topics were mentioned.

[2] November, High expectations, about the energy use and greenhouse gas emissions from golf courses.

[1] May, Data to support an anecdote about decreasing organic matter in the top 10 cm of putting greens with minimal coring or topdressing.

Two Excellent (and free) Resources about Turfgrass Diseases

Controlling turfgrass diseases is one of the most important ways turfgrass managers modify the growing environment to produce the desired playing surfaces. Two resources that I find quite useful as reference material and as a source of new information are the Turf Diseases website and the University of Kentucky's Chemical Control of Turfgrass Diseases 2011.

Turfgrass_diseases
At the Turf Diseases site, you will find updates about disease outbreaks, control options for different diseases, new information about ongoing research, and witty banter from an interesting group of university professors. The associated page on Facebook also contains information that can help turfgrass managers in their efforts to produce better playing surfaces.

Chem_control_disease_2011 The 24 page Chemical Control of Turfgrass Diseases 2011 was written by Paul Vincelli and David Williams at the University of Kentucky and is a guide that you are likely to find useful throughout the year. Not only does this document contain the latest information about fungicides and which products are most effective at controlling specific diseases, it also discusses cultural controls of turfgrass diseases and gives suggestions on how to minimize disease intensity. There is a wealth of useful information in this free document.

Nozzle Selection for Spraying Pesticides and Fertilizer

Sprayer-nozzleOne of the topics I will discuss at next week's Sustainable Turfgrass Management in Asia 2010 seminar is nozzle selection, spray droplet size, and water volume. Depending on the product (fertilizer? herbicide? fungicide?) being applied, its mode of action, and the reason for the application, one can choose the nozzle type that will produce the most effective spray pattern on the turf.

The Turf Diseases blog has some good posts on this topic, including photos that show the drastic differences in spray patterns between different nozzles and tips on improving disease control by proper nozzle selection.

I also recommend reviewing the guide to nozzle selection that Tee-Jet publishes, available for download here.


Bermudagrass White Leaf

Bermudagrass-white-leaf

I recently wrote about bermudagrass white leaf, a mollicute disease seen in Asia on bermudagrass, at the Turf Diseases blog. See the bermudagrass white leaf post here. If you have this problem on your grass, it will probably go away in time as healthy plants grow over the dying chlorotic plants. For more information about ATC's investigations of bermudagrass white leaf, download the Field Day Book from 2008 at the Turf Information page of the ATC website.


The Wow Factor, Seashore Paspalum and Dollar Spot

The Wow Factor, Seashore Paspalum and Dollar Spot is now posted on the Turf Diseases Blog and may be of interest to those who manage seashore paspalum in Asia.

I will be contributing some posts to the Turf Diseases Blog on topics related turfgrass diseases in Asia. For information about all types of turfgrass diseases on warm and cool season grasses, and for advice on the management of these diseases from expert plant pathologists, you will want to read the Turf Diseases Blog this year.
