ATA TURF TIMES: J. Scott McElroy, PhD – Professor, Department of Crop, Soil, and Environmental Sciences Auburn University

As a scientist, I hesitate to make predictions such as those a fortune teller might reveal. I wince when I hear people speaking with absolute certainty that this or that will happen in the future. That some team will win, some politician will lose, or that some event will occur is often pure speculation. Absolute predictions are nonsensical, and an affront to probabilistic thinking. To think probabilistically is to think in terms of the percentage of probability that something will occur. This is the foundation of good science.

Having said that, it is highly probable that in the next 10 years autonomous technology will gain a significant portion of the professional and consumer market in the United States. I base this prediction on four pieces of evidence:

1. Robotic technology has already captured a significant portion of the technology in Europe.

2. All major brands that market traditional mowing technology or mowing equipment are developing robotic technology.

3. At one count there were over 40 additional startups and companies developing all manner of robotic technology, including mowers, painters, and sprayers.

4. The labor shortage will be sustained into the foreseeable future and could potentially increase (https://www.wsj.com/articles/america-still-has-a-worker-shortage-d0c65166).

But here I am addressing the “Contrarian’s Guide to Turfgrass Robotic Technology.” To the robotic contrarian, any positive arguments I present regarding this technology will likely fall on deaf ears. To the contrarian, only seeing is believing. Once my prediction has come true, the contrarian will adopt the technology as self-evident. Don’t get me wrong. Skepticism is a good thing. However, a complete understanding and realistic expectation of what robotic technology can do and where the technology is going is necessary to the healthy skeptic. I want to convince the contrarian that instead of waiting for the technology to be tested by fellow industry partners, they should begin testing and evaluating it themselves. With that in mind, I present this article to the contrarian on fundamentals of robotic technology today.

“The Technology is Just Not There Yet.”

This is the contrarian’s favorite phrase. In frustration I respond, “Where is There?” or even “What is There?”. If the technology has not arrived at the point where it can be adopted, what are its current limitations?

What irks me so much about this critique is the underlying assumptions about imagined technological characteristics that may not even be possible. The contrarian’s perception of automation is that the technology can be easily set up with little or no planning or understanding of the technology. That it may be deployed for use with little, or no, oversight. The phrase, “The Technology is Just Not There Yet,” is normally rooted in some technological advancement in artificial intelligence, or machine learning, that the contrarian has developed based on their perception of technological development, or maybe even a touch of science fiction.

My response is “The technology is what the technology is.” 2022 might as well have been ten years ago when it comes to robotic and autonomous technology in the United States. 2023 saw an incredible number of major advances. These include allowance for extended range connection to 4G and network RTK systems; daisy chaining of reference station signals for greater lengths; creation of virtual zones that can vary in direction, speed, and height of cut; and mobile deployment across multiple sites. The technology launched in 2023 will be the basis of robotic technology for the next five to ten years.

To the contrarian, if you were talking about 2022, I agree.

PENNSYLVANIA TURFGRASS:

What happens when turf professionals from Penn State Cooperative Extension, the world of professional sports, and the private sector all team up to work on a community turf project? It results in a special “feel-good” synergy that gets the job done and also has great community impact. Westinghouse Academy, an inner-city high school in Pittsburgh serving Wilkinsburg, Homewood, Point Breeze, East Liberty and Highland Park, is getting a safe new football practice field and green activity space, thanks to the combined efforts of Head Coach Donta Green, Extension Educators Jeff Fowler and Michael White, and Thomas ProTurf contractor Jeremy Thomas, who was able to also enlist the help of Steelers groundskeeper Thomas Goynes. We asked where the vison for this project came from and how this turf power team had come together, and it was an inspiring story (Photo 1).

The Bulldogs and Their Coach

The Westinghouse Bulldogs have generated a lot of excitement in Pittsburgh over the last two years. In the words of the Pittsburgh Post-Gazette, last season, Westinghouse had “a fairy tale season that ended at the doorstep of a state championship.” The Bulldogs (14-1, 4-0) were the first City League school to reach the state finals since Perry High School 25 years ago. Under the charismatic leadership of Coach Donta Green, they were state runner-up in 2022, and Green was quoted as saying, “Our guys are just itching for another shot and another opportunity to do that” this season.

According to Jeff Fowler, “Coach has done some amazing things in his two years with the Westinghouse football program.” Donta Green is also the executive director of The Trade Institute of Pittsburgh, a nonprofit vocational training provider dedicated to providing opportunities for individuals with barriers to employment who need additional support to begin their careers. Founded in 2013, the Trade Institute is located in the Homewood community of Pittsburgh. The football team at Westinghouse reflects this demographic — 65% of the players’ fathers are incarcerated and will have barriers to employment when they re-enter society. And the student athletes who carried the Bulldogs to success last season have not only had to work hard to achieve this excellence, but they have also had multiple barriers to overcome – not the least of which was a practice field that was, like many neglected urban landscapes, run down and treacherous underfoot.

The Connected Community Initiative

Penn State Extension Educator Michael White is a Pittsburgh-based Program Specialist in the Connected Community initiative. He plays a vital role in developing programs that aim to provide equitable opportunities for underserved communities, empowering them to achieve success and personal growth. His goal is to leverage science-based Extension practices to respond to the diverse needs of urban communities, fostering a more vibrant and inclusive environment. “Many of the local green spaces are in distress,” he notes. “However, the Westinghouse Green Space initiative became a priority for me because of its potential to impact so many youths.”

White brought in his colleague, turf expert Jeff Fowler, to assess what it would take to renovate the field at Westinghouse Academy. Based on Fowler’s recommendations, White wrote grants to finance the purchase of seed and fertilizer and arranged to offer training for the school staff on care and maintenance of the new field. Jeff Fowler says he then got excited about the project and invited several of his KAFMO colleagues to get involved and lend a hand – and suddenly, the Westinghouse Green Space project was taking off (Photo 2)!

Jeremy Thomas of Thomas ProTurf is a graduate of Penn State’s Turf Science program and an active KAFMO member who contracts with Steelers groundskeeper Thomas Goynes.

NEW ENGLAND BLADE:

Everyone wants better employees and today, that usually requires growing them internally. By starting with a high-potential worker and developing them intentionally, companies are able to build a near-ideal employee ready to tackle their specific issues. But employee development only occurs in the right environment.

Employee growth is not unlike plant growth in that the result is dependent primarily on environmental factors rather than genetic make-up. Unfortunately, managers rarely audit their environment for employee growth potential and even fewer have clear ideas about the factors that would make a strong growth environment. Here are the seven environmental factors that should be considered when cultivating a culture of development:

Advanced Expertise – Employee growth can only occur when there is guidance from an experienced mentor who is setting the pace for production and sharing knowledge. Everyone should have a committed coach or mentor.

Continually Challenged – Advancing to the next professional level never happens by accident, so an environment where everyone is challenged to reach higher levels of performance creates the tension needed to advance intentionally.

Future-Oriented – A team which is focused on past mistakes doesn’t have the right outlook to grow their team. Growth is always the result of forward thinking where a better reality is a goal and positive intent around its achievement is embraced.

Affirming Atmosphere – Development takes a lot of extra work beyond simply the status quo so teams that encourage each other to the next level of their skills are the ones that usually stick it out to see the results. It is the consistency of effort over long periods of time that is enabled through encouragement and brings true results.

Mission Driven – When team members understand what their company does to enhance the lives of their customers and how their role contributes to making a difference, they are more likely to wake up excited and be driven to be the best version of themselves. This energy is essential to growth.

Failure is Embraced – When we learn new skills and put them into practice, failing is a large part of the learning journey. In fact, learned experience is the quickest way to actually know anything. But a negative reaction to mistakes will deplete growth momentum, so wise team leaders expect failures and embrace the opportunities they provide.

Mutual Advancement – People always work best when they’re working together, so teams where every member is growing are far more likely to see positive results. The best environments for growth have individualized and continuous development happening for every person and the culture is one of learning. •

In 2023, our team conducted several fungicide and nematicide trials at the UMD Paint Branch Research Facility to evaluate their efficacy against various turfgrass diseases and nematodes. The trials were mainly focused on:

• Brown patch and dollar spot affecting fairway and green height creeping bentgrass.

• Brown patch on home lawn tall fescue.

• Gray leaf spot on perennial ryegrass.

• Nematicide trials on bermudagrass and perennial ryegrass.

Preliminary findings from these experiments were presented at our Field Day in July. Currently, we are concluding the studies and analyzing the data. For the trials with registered fungicides, reports detailing our observations and results will be made available on our program’s website

(https://sites.google.com/view/umdturfgrasspathology).

In terms of disease progress in the season, May and early June were relatively drier and cooler than the usual averages for the season. This led to a delayed onset of diseases at the farm. However, as summer progressed, the typical weather patterns prevailed, leading to elevated disease pressure. Most diseases, including the brown patch and dollar spot, peaked during this period. By mid to late September, we observed a significant reduction in the prevalence of most diseases.

Turfgrass Variety Trial Update

By Geoffrey Rinehart

Did you know that the University of Maryland turfgrass research program conducts ongoing experiments to evaluate varieties from several different turfgrass species? Using data from these trials and in coordination with data collected by turfgrass researchers at Virginia Tech, and the professionals from the Maryland Department of Agriculture and Virginia Department of Agriculture Seed Laboratories, the “Maryland-Virginia Recommended Varieties List” is updated on annual basis to summarize the top varieties from several of the major turfgrass species used in the Mid-Atlantic provided the varieties are available as certified seed and has been tested by either or both the MD or VA Seed Labs. Typically, these trials are conducted as part of the National Turfgrass Evaluation Program’s (NTEP) research efforts. Previously high-performing varieties which are not included in the most current NTEP trials are planted and evaluated in supplemental trials so that researchers can continue to evaluate these cultivars as one of the criteria for them to remain on the recommended list. NTEP conducts variety trial testing for all major cool- and warm-season turfgrass species in over 35 states throughout the country to identify top-performing varieties both on a national and regional level. The University of Maryland’s NTEP trials, as well as the Annual MD/VA Recommended Varieties List, are an important part of evaluating varieties both locally/regionally and nationally and providing you, the Maryland Turfgrass Professional, with the varieties which will grow well and produce the best turfgrass for your customers. In fact, one of the requirements sod farmers in Maryland must meet is to utilize only varieties found on the MD/VA Recommended Varieties list.

This summary of information can be found in University of Maryland Extension publication TT-77. This and other UMD Extension publications are available to all members and industry professionals on the Maryland Turfgrass Council website. Currently, the UMD turfgrass program has trials evaluating bermudagrass, zoysiagrass, tall fescue, “fine” fescue (includes Red, Chewings, and Sheep Fescues), and Kentucky bluegrass (the newest trial of which was planted in early October 2023).
