The Cornell Turf Show: fastest 30 minutes in turf

Every other Friday, starting on March 12th and ending the second week in May, Cornell Turf Guru, Frank Rossi, will have a guest talking about sports field management. This week, former graduate student, Chris Sitko, will be on to discuss sports field safety and the high demand school districts will be placing on sports field early in the season. Topics and speakers will be updated on the Cornell Turf website, Twitter account, and Facebook page as they are scheduled.There will be a golf focused webinar every Thursday through this time and topics relevant to lawns will alternate with sports fields on Fridays. It’s a good idea to check on the topics for those not specific to sports fields, as there might be something of relevance to you. For example, the webinar series kicks off Thursday, March 11th, with Art Degaetano, Professor in the Cornell Department of Earth and Atmospheric Sciences, who will provide us with a winter weather review.

Can’t make a session live? Similar to last year, the webinars will be recording and posted to YouTube. (You can check out the 2020 webinars here.) We’ll also be posting the audio as podcasts for those who enjoy that medium.

All the webinar information can be found here on our website which will be updated periodically with guests and recordings: https://turf.cals.cornell.edu/news-2/webinars/

Fertilizer and the Law

A deep, extensive root system helps cool-season grasses build up reserves to get through the winter, green up top growth in spring, and minimize vulnerability to insects, diseases and summer drought. Nutrients released from the soil, grass clippings and late season fertilization (feeding) will promote root growth.Lawn Care: The Easiest Steps to an Attractive Environmental Asset

Fertilization helps grow healthy turfgrass. Dense stands outcompete weed seeds. Extensive roots can withstand some insect feeding without impacting turf quality. Proper fertilization provides your grass with the proper nutrients for growth and recovery.

And now is one of the best times for fertilizing sports fields, but it has come to my attention that the legality of fertilizer application is in question. There is a rumor that one needs to be a certified pesticide applicator to apply fertilizer to school grounds. We’ll label that as fake news. Addressed in an earlier blog, some wonder if they are restricted under the Child Safe Playing Fields Act. The answer to that question is no.

But that doesn’t mean that there are no fertilizer rules. Here are the caveats:

  • Combined fertilizer and pesticide products (such as weed and feed) are covered under the Child Safe Playing Fields Act and do need to applied by a certified pesticide applicator.
  • Fertilizer use does fall under the NYS Nutrient Runoff Law, which prohibits:
    • Applying fertilizer containing nitrogen, phosphorus, or potassium between December 1 and April 1 (Nassau and Suffolk County have their own local laws restricting application dates)
    • Applying fertilizer containing phosphorus unless you are establishing a new lawn or a soil test shows the need for phosphorus
    • Applying fertilizer within 20 feet of a water body
    • Leaving fertilizer on impervious surfaces such as sidewalks, parking lots, or driveways (fertilizer must be swept up, not washed off with water)

So now that we know fertilizer can be applied to school grounds, what is the minimum that should be done now to produce pest resistant turfgrass on fields that are used year round?

Fertilizing in the fall encourages more root growth.

  • Fertilizing -Apply 1 pound of 50% water soluble nitrogen per 1,000 sq. ft. in September and ½ pound of 100% water soluble nitrogen in mid-October. Note – if you do not have irrigation, it is worth waiting until the day before rain is predicted to ensure the fertilizer is watered in.
  • Mowing -If the grass is growing, mowing should be conducted at least twice a week. Mowing increases shoot density by increasing tillering (stems that develop from the crown of the parent plant). More tillers means more traction and cushioning.
  • Overseeding -Seed perennial rye at 2 pounds per 1,000 sq. ft. weekly in high-use areas. The athletes’ cleats will make the necessary seed to soil contact. This year’s drought makes this practice tricky. If you can borrow irrigation equipment, do so.

What if I can do more than the minimum?

  • Fertilizing -Conduct a soil test to see if other nutrients are needed in addition to the nitrogen.
  • Cultivating -Concentrating on high-use areas, solid tine cultivate in multiple directions to maintain infiltration of air and water.
  • Overseeding -Have a mixture of one part seed to ten parts soil available so coaches and players can repair divots left after heavy use.
  • Watering -Maintain adequate soil moisture but keep surfaces dry to maximize traffic tolerance. Irrigate if you can see your foot prints after walking on the turf.

Our New Look!

Back in 2013, the Northeast School IPM Working Group (NESIWG) received a Partnership Grant from the Northeastern IPM Center to develop a Best Management Practices (BMP) website.

Reducing pest and pesticide exposure is important for children, just as it is for district staff and visitors. But schools are especially challenging to manage because they include such varied and heavily used settings such as classrooms, cafeterias, laboratories, auditoriums, theaters, playing fields, playgrounds and gardens.

With the help of many contributors, the NESIWG both created and collected resources for school IPM. We wanted to help administrators, school boards, parents, teaching and support staff, athletic directors, groundskeepers, kitchen staff and custodians how a designated pest management plan can reduce both pests and the need for pesticides. The website was a success.

By 2018, NESIWG members saw the need to update old links and fill out gaps in the content. Eager to keep the website a useful and comprehensive resource, the working group applied for and received a NEIPM Communications grant. Again using focus groups, the following changes were made:

  • a reorganization of the pest species list,
  • additional information on relevant pesticide use regulations in all Northeastern states,
  • grouping resources by stakeholder roles,
  • the addition of two new pages: Breakfast in the Classroom and Playgrounds

Additionally, the recent grant included an update of the working group’s homepage, a new ranking of regional school IPM priorities, a current membership list and an index of school IPM contacts in the Northeast.

What we’re pondering

“An investment in knowledge pays the best interest.” –  Benjamin Franklin

We at the New York State IPM Program work to ensure we are up on the latest information that is important to help you protect students and staff from pests. Here are some resources that have recently crossed our desk.

Educating Staff

IPM in any setting is not an one-person job. In schools, without help from staff and students, IPM is nearly impossible. P also stands for people! Janet Hurley Extension Program Specialist III – School IPM from Texas A&M AgriLife Extension Service discusses The Importance of Educating Staff about Your IPM Program.

Stop School Pests has changed its name to the Pest Defense for Healthy Schools to emphasize its dedication to creating healthy, safe spaces for students and school staff by preventing pest problems such as mice, cockroaches, bed bugs, ants, and lice. The online professional training is targeted for specific school audiences including custodial staff, school nurses, grounds managers, school administrators, maintenance professionals, teachers, food services professionals, and pest management professionals.

 

School Safety

Cornell University turf specialist Frank Rossi talks about how to manage athletic fields to reduce injuries.

This isn’t new, but it’s a must see for all school administrators, athletic, and grounds department staff. Safe sports field management will help to reduce the risk of injuries.

Frank Rossi, Cornell Turfgrass Extension Specialist, describes basic level of care of athletic fields in the video, Duty of Care.

Ticks

With the funding of the Don’t Get Ticked New York campaign, we have been pretty dedicated to (read: obsessed with) keeping up-to date on tick information. Here is some of the latest news.

The Public Tick IPM Working Group has created a document, Tick Management Options, showing some of the most effective control strategies. A number of these options would require an emergency exemption and application by a certified pesticide applicator.

Researchers at the University of Cincinnati looked into the behavior of hungry ticks. The metabolism of ticks that had not fed for more than 36 weeks increased by as much as 100% and remained high for weeks. This has implications for adult ticks that failed to find a host in the fall. They can not only be active when the temperatures are above freezing, but will be more active in searching for a new host during the winter when the public is least likely to be thinking of tick protection. Hungry ticks are also more likely to venture into less desirable habitat – like your athletic fields. Hungry ticks work harder to find you

An Asian longhorned tick showed up in a sample of lone star ticks collected in Rockland County. The one with the short, stubby mouthparts is the longhorned tick.

Asian longhorned ticks are a troublesome new addition to an already difficult issue. First discovered on a farm in New Jersey in August 2017, we now know that they have been in the United States since at least 2010 and has been identified in nine states, including New York. So far they don’t find humans to be a particularly attractive host and tested ticks have had any disease pathogens. Which is great news. But, there is a lot we still don’t know about this tick. A recent webinar Discussions on the Invasive Longhorned Tick, Haemaphysalis longicornis organized by the Northeast Regional Center for Excellence in Vector-Borne Diseases provides a lot of information

Frequently Asked Questions:

In the simplest of terms, the more use a field receives, the more preparation it will need prior to the initiation of use, maintenance during the traffic period, and recovery maintenance following the traffic. Photo: Bob Portmess

My fields are showing wear stress already after three weeks of use as a result of rainy and now very warm conditions. I’m trying to speak with coaches and parents about field use under these conditions. They keep asking the same question of me, “how many hours of use CAN the field handle”? Can you help?

First big kudos for recognizing the need to communicate with your clients regarding the conditions and safety of the fields. Effective communication is the consistent characteristic of successful professional sports turf managers. We have provided some useful tools to assist with the general information for players, parents, coaches and athletic directors at http://safesportsfields.cals.cornell.edu/coaches.

Additionally, there will not be any hard fast answer to the question without some qualification and understanding of the root zone, type of use, maintenance inputs, and visual quality expectations.

Our first responsibility is to ensure player safety as measured by field hardness, evenness and traction; other field issues become subjective as to what constitutes an “acceptable playing surface”. Again, there are gray areas when discussing amount of use, as poor weather experienced over the last 30 days has led to significantly more wear stress and field decline than expected under average weather patterns. Finally, larger amounts of managed field area that allows for dispersal of focused traffic and the availability of synthetic surfaces both significantly increase overall amount of natural grass playing field use.

Rootzones:

Soil properties impact traffic tolerance.

Loamy soil root zones with some drainage and some irrigation can withstand more than the average amount of use. Sand-based fields with excellent drainage can withstand significantly more than the average amount of use.

Type of Use:

Any type of field use that results in repetitive focused traffic, i.e., between the hash marks, goal mouths, sidelines, will reduce the amount of field use. Larger male athletes create more traffic stress than lighter female athletes. Youth sports with smaller athletes and smaller field dimensions that can be rotated, allow for much more use than average. Again rotation allows for dispersal of the traffic.

Schools and community parks are able to provide different levels of field maintenance based on their budget and the resources on hand that include labor (knowledge and experience), equipment and products. Other factors play into shifting resources, such as desired quality, type of field and use (practice vs game fields).

Maintenance Inputs:

Reasonable care of fields is expected as outlined in ASTM F2060 for cool season natural grass fields – this will include some amount of field rest and recovery as outlined in these important maintenance schedules. In the simplest of terms, the more use a field receives, the more preparation it will need prior to the initiation of use, maintenance during the traffic period, and recovery maintenance following the traffic. No maintenance program will compensate for overuse that leads to decline in field quality below acceptable levels and will need a routine turf replacement program as seen in most professional sporting venues.

Visual Quality Expectations:

Players, coaches, parents and Athletic Directors have the right expect to safe playing fields. Sports turf managers must have field safety measurements to effectively determine when field use leads to decline in safety. The visual quality of the field often is correlated to field safety but not always, as a soft bright green field with poor traction is less safe than a slightly brown firm even surface.

In the end, general guidelines suggest good field conditions can be maintained with reasonable care at between 400-600 hours of use per year per field. Beyond 600 hours of use expect a loss in field quality and significant thinning and wear areas even under ideal conditions.
