Aerification, it’s that time of the year again!

“HGCSA Corner”

from the HSGA Newsletter – September 2024 – Issue 134
By Nolan Johnson
Director of Operations & Agronomy Makalei GC

Aerification, it’s that time of the year again! As Superintendent’s, we see the look of frustration on your faces as you unknowingly show up to a course that were recently punched. Let’s face it, no golfers are ever thrilled to arrive at a course, only to find that they will be putting on greens that have just been aerated. There is a misconception that golf course Superintendents love aeration and we do it to make golfers mad. Nothing can be further from the truth.

From the Maintenance side: it costs a large amount of money to complete, it is time consuming, it wreaks havoc on equipment/mower reels/bedknives, and staff morale usually declines for the backbreaking work.

From the Operations side: there is usually a loss in revenue, staff has to deal with frustrated guests, the greens are slower and difficult to read, the roll is almost always affected, and sand gets everywhere.

So why do it? Because it’s the single-most important practice done on the course:

  1. Relieves Soil Compaction: Over time, the constant foot traffic and weight of maintenance equipment can compact the soil, reducing its ability to absorb water and nutrients. Aerification alleviates this compaction, allowing roots to grow deeper and stronger.
  2. Enhances Water and Nutrient Uptake: The holes created during aerification allow water, fertilizers, and air to reach the root zone more effectively. This improved access supports the turf’s health, making it more resilient against drought and disease.
  3. Reduces Thatch Buildup: Thatch, a layer of dead grass and organic matter, can accumulate on the surface and hinder water infiltration. Aerification helps break up thatch, preventing it from becoming too thick and suffocating the grass.
  4. Promotes Healthy Root Growth: By creating spaces in the soil, aerification encourages roots to expand and grow deeper. This leads to a more robust root system that can better withstand environmental stresses.

  • "Have we lost the battle against CRB?"
  • “Are CRB traps just attracting CRB to my property?”
  • “Is it true that once CRB is present, it's impossible to protect my plants?”
  • “Is CRB management only the responsibility of agricultural professionals and not homeowners?”
  • “I've been told mulching is a surefire way to attract CRB. Should I avoid it entirely?”

Join Arisa Barcinas, outreach associate with CRB Response, and Elizabeth Speith from 643pest.org and the Hawai'i Invasive Species Council (HISC), for an enlightening dive into the Hawai'i Coconut Rhinoceros Beetle (CRB) Communications Plan and current CRB status. The Hawai'i CRB Communications Plan aims to enhance our collective understanding and foster collaborative community action to manage CRB across the state. They will also tackle strategies to combat misinformation and encourage an open discussion to address common misconceptions. The plan was created by a collaboration of CRB communications experts from multiple agencies and groups across the state, reflecting the unique populations and situations faced on each island and underscores the multi-agency approach essential for effective CRB management.

The Hawai’i Golf Economy – An Economic Impact Analysis

Discover the economic heartbeat of Hawaii’s golf industry!

We are thrilled to announce the publication of the "Hawai’I Golf Economy 2023 Economic Impact Analysis." This comprehensive report, released by The PGA of America – Aloha Section and Foundation, sheds light on the significant economic contributions of golf to our home islands.

Golf isn't just a sport; it's an integral part of Hawaii's economy, supporting jobs, generating revenue, and driving tourism. Through this analysis, we gain valuable insights into the economic footprint of golf in our state, reaffirming its status as a vital industry.

As stewards of Hawaii's golf courses, it's crucial for us to understand and appreciate the economic impact of our sport. By sharing this report on our website, we aim to inform, educate, and advocate for the continued growth and prosperity of the golf industry in Hawaii.

We encourage all members, stakeholders, and golf enthusiasts to explore the findings of the "Hawai’I Golf Economy 2023 Economic Impact Analysis" and join us in celebrating the economic power of golf in Hawaii.

Together, let's continue to champion Hawaiian Golf and its positive contributions to our communities and economy.

Key highlights from the Economic Impact Analysis include:

  • Combined financial outlay of $393 Million annual from operational revenue and capital investments.
  • Over $1 Billion dollars generated in annual golf tourism and golf-related retail spending.
  • Homes values adjacent to golf courses increase property values by an estimated 32% resulting in real property tax collections in golf course communities amounting $2,695,761.
  • Direct economic impact of $1.8 Billion and $1.6 Billion from indirect economic impact from core industries bringing the total economic contribution to the Hawai’i economy of $3.4 Billion dollars.

Hawaii Project Meeting with GCSAA

A very brief summary: EPA is responsible for registration and re-registration of pesticide using the “Federal Insecticide Fungicide and Rodenticide Act”. There is potential and maybe current litigation by Non-Governmental Organizations against the EPA for not adhering to the “Endangered Species Act.” Hawaii has a large number of endangered species…..golf courses use pesticides. Use, regulation, registration and re-registration of pesticide use on golf courses is up for evaluation.

Message from Russell Dooge, CGCS
Executive Director HGCSA

Please read the email communication from Chava (Director, Government Affairs – Golf Course Superintendents Association of America), this is about the EPA and it concerns Hawaii golf courses.

THIS IS IMPORTANT

Russell Dooge, CGCS

Hi everyone,

It has been a while since we talked to EPA about the Hawaii pilot. They have not rolled anything out yet but it was mentioned yesterday at an IR-4 meeting in Raleigh. I have not heard any more news on the proposed roundtable in Hawaii in October/November. I will let you know when I do.

EPA is dealing with Hawaii separate from the other 49 states. They have rolled out a much more potentially problematic pilot called the Vulnerable Species pilot affecting the 49 states. We have been focused on it the last month. We are working with supers in Milwaukee right now on preparing comments to EPA.

I wanted to bring back to your attention the two data sets that Jennifer Connolly shared with me:

Golf Courses | Hawaii Statewide GIS Program – golf course data layer from State of Hawaii – where golf courses are located

Advancing Transparency of Endangered Species Act Evaluations Through Publicly Available Data | US EPA – endangered species data – where endangered species are – Jennifer said to look at the Layers section in the middle of the page

Ahead of our next discussion with EPA on the Hawaii pilot, would you mind having members of the Hawaii GCSA board take a look at both of these data sets and provide any insight. I am interested to know if the golf courses are being mapped correctly. Dan said things were not accurate around him. Also, I am interested to know what types of endangered species are listed at or near your golf courses.

Also, please have your chapter members sign up for the FIFRA-ESA 101 webinar we are hosting on September 27. The USDA and Bayer and Syngenta are helping us educate the membership on the upcoming ESA challenges and alerting everyone to the proposed pilot projects.
