Golf Course Program
Greener Greens
Fairer Fairways
Your course spends a fortune
fighting problems that start
in the soil.
The average 18-hole course spends $25,000–$100,000+ on fertilizer annually and nearly $35,000 on fungicides alone — year after year, with the same problems coming back. The chemistry changes. The soil never gets better. There's a different way.
Two perspectives.
One shared goal.
Whether you're managing the P&L or managing the turf, the goal is exactly the same — a course that performs season after season, keeps members satisfied, and doesn't demand constant intervention to hold together. A healthy soil biology program delivers that. It just speaks a slightly different language depending on who's listening.
⛳ FOR OWNERS & GENERAL MANAGERS
Chemical inputs are one of the largest controllable line items on your P&L — and they don't produce an asset. Every bag of fertilizer, every fungicide application is an expense that delivers a temporary result and leaves the underlying soil biology no better than before. Documented programs using biological soil amendments have reduced chemical input costs by up to 70% on 18-hole courses, with savings exceeding $40,000 annually. That's not a rounding error. That's real margin recovery.
🌱 FOR GOLF COURSE
SUPERINTENDENTS
You already know the soil is the foundation. You've watched courses that rely entirely on synthetic inputs fight the same disease pressure, the same recovery problems, the same summer stress year after year. The chemistry gets more sophisticated. The soil gets weaker. Biological soil amendments work differently — they rebuild the living ecosystem beneath the turf, producing stronger root systems, better stress tolerance, and playing surfaces that hold up through the season without constant intervention. The research is there. The results are documented.
Synthetic inputs feed the plant.
Yet starves the soil.
🔄
The dependency cycle
Dead soil biology can't support turf without constant synthetic inputs. Every application makes the next one more necessary.
☀️
Summer stress vulnerability
Shallow roots in dead soil can't access water or nutrients during heat stress. Recovery is slow, expensive, and visible to members.
📉
Thatch accumulation
Without active soil biology to break down organic material, thatch builds up — creating more problems and more expense to manage it mechanically.
🍄
Disease pressure builds
Turf in biologically depleted soil is weak turf. Weak turf attracts disease. More fungicide follows — treating the symptom, not the cause.
💧
Environmental & regulatory pressure
Chemical runoff concerns, water quality mandates, and community scrutiny are increasing across the industry. Courses are being asked to do more with less chemical impact.
🏌️
Playing surface consistency
Members notice. Thin turf, slow recovery after aeration, inconsistent green speed — the biological health of your soil shows up on the scorecard.
This isn't new.
It's justfinally being applied to golf.
University studies, USDA-funded trials, and documented results from golf courses across the country have established a consistent picture: biological soil amendments — specifically worm castings and castings extract — produce measurable improvements in turf health, root development, and long-term input cost reduction.
USDA / SARE FUNDED TRIAL
Up to 70% reduction in fertilizer and insecticide use
A federally funded agricultural research trial documented that worm castings and castings extract reduced fertilizer and insecticide use by up to 70% on an 18-hole golf course, with documented annual savings exceeding $40,000.
UNIVERSITY OF TENNESSEE — DR. JIM BROSNAN
Proven increase in root area and root mass
Using X-ray phenotyping technology, University of Tennessee researchers proved that turf exposed to worm castings extract showed measurably increased root area, total root length, and root distribution by depth — backed by 17 peer-reviewed state and federal research grants.
USGA DOCUMENTED CASE STUDY
Real-world course integration with measurable results
The USGA documented a golf course's integration of vermicompost into their turf program, finding that as little as 10% vermicompost blended with sand provides excellent divot mix and topdressing material while reducing waste hauling costs and improving soil health metrics.
MULTI-COURSE TURF TRIALS — GOLF COURSES ACROSS THE U.S.
27.9% longer roots on greens.
34.1% longer roots on fairways.
Root plug comparisons across multiple golf courses documented that bi-weekly castings extract applications increased root length 27.9% on greens and 34.1% on fairways vs. untreated control plots. In a separate fall trial, thatch reduction was observed just 8 days after application at a monthly rate — providing superintendents a measurable, rapid-response tool for one of turf management's most persistent problems.

LOCHINVAR GOLF CLUB — HOUSTON, TX · GOLF DIGEST TOP-RANKED PRIVATE CLUB
"I have used worm castings liquid extract on all my greens for the past five consecutive years. Each year the greens have been easier to manage and looked better to the members. Out of 32 years at the course, this has been the best one ever. The greens did GREAT." — Golf Course Superintendent, Lochinvar Golf Club
OAK HILL COUNTRY CLUB — PITTSFORD, NY · HOST OF PGA CHAMPIONSHIP, US OPEN & RYDER CUP
Scott Wheeler, former head horticulturalist at Oak Hill Country Club, documented the program's results publicly: "It's all about the roots. Once you develop a strong root system, all the great benefits follow." Jeff Corcoran, superintendent at Oak Hill, has spoken extensively about biological extract programs and their role in rootzone management at one of America's most prestigious courses.
STONEHENGE GOLF & COUNTRY CLUB — RICHMOND, VA
Chad Karr, CGCS, superintendent at Stonehenge Golf & Country Club, documented two consecutive seasons on a biological castings extract program and shared his results publicly — noting measurable improvements in turf performance and reduced intervention requirements across the course.
MENDON GOLF CLUB — ROCHESTER, NY
Mike Armstrong, superintendent at Mendon Golf Club, incorporated biological castings extract into his greens agronomic program and documented the results — with the most significant outcome being larger root mass in bermuda fairways and strong root development in the mat layer of ultradwarf bermuda, producing turf that held up through the full season.

Data
We don't just sell it.
We prove it.
These photos were taken on our own property in West Tennessee. Same field. Same weather. Same zero mowing for 2.5 months. The only variable was extract application in the fall of 2024. The left side received no treatment. The right side received our biological castings extract program.
What this means for a golf course: This growth differential isn't a liability — it's proof that the biology is working. On a managed turf program, that same biological energy goes into root depth, stress resilience, and disease resistance rather than unchecked top growth. The biology that drives this result is the same biology that builds the playing surfaces your members expect.
One program.
Whole course.
No complicated zone-by-zone protocols. The same biological program works across greens, tees, and fairways — simple enough for any maintenance team to implement alongside existing practices.

Worm Castings Extract
LIQUID BIOLOGICAL APPLICATION
5 gal / acre
Applied monthly throughout the growing season
Spray-applied as a soil drench or foliar spray. Compatible with standard spray equipment and irrigation injection systems. Delivers over 1,400 different microbes in suspension directly to the root zone — providing the diverse biological population that roots need to access nutrients efficiently. Fast-acting, chemical-free, and measurably effective. No mixing complications. No timing windows. Apply and let the biology work.

Worm Castings
GRANULAR TOP DRESS
10 lbs / 1,000 sq ft
Twice per year — early spring and late fall
Applied with a standard drop spreader. Lab-tested, biologically active, 1/8" sifted for clean application. Adds organic matter, feeds existing soil biology, improves soil structure and water retention. Pairs with the extract program to build long-term biological capacity — not just a seasonal fix.
Both products are 100% organic, safe for immediate play after application, and compatible with existing IPM programs. The castings extract can be integrated into irrigation injection systems for courses that prefer automated delivery. TLSS provides application guidance and follow-up support for every program — we're not a drop-ship operation. We show up.

Will it be your course?
Biological soil programs are coming to West Tennessee golf. The research is too strong, the cost savings are too documented, and the industry pressure to reduce chemical inputs is only increasing. The question isn't whether this happens here — it's which course leads and which ones follow.
