SOIL WETTING AGENTS FOR LAWN CARE AND SPORTS TURF.
Advanced Soil Wetting Agents for Professional Turf.
Soil wetting agents are important tools to manage soil moisture in high performance turf. Whether you deal with hydrophobic soils and sands that repel water, localised dry spot (LDS) or poor water infiltration, Gilba Solutions has one of the best ranges of soil wetters in Australia.
Our soil wetters are proven, safe to the environment, and you can use them on all turf types. They help you to drive water into the soil profile, produce healthy turf, and reduce the need to hand water.
Why Soil Wetting Agents Matter in Turf Management.
When you use these correctly, modern soil wetters help:
- Improve how water moves into the soil. They help water to move into hydrophobic (water repellant) soils.
- Improve the distribution uniformity (DU) of water in the soil.
- Reduce LDS and localised dry patches.
- Help grow a deep root system.
- Increase your irrigation efficiency and reduce waste.
Soil surfactants aren’t just a fix for dry patch. They are a tool for high performance areas like sports grounds, greens, tees, collars, and fairways.
What Do Soil Wetting Agents Do?
- Reduce surface tension. When water molecules attach to each other it creates surface tension. Soil surfactants interfere with this attraction, and reduce the surface tension.
- Counter water repellant Soils. In hot, dry weather sandy or high OM soils can become hydrophobic. Surfactants make it easier for water to evenly move into the profile.
- Improve water penetration into a soil.
- Soil wetting agents improve water move evenly through the soil profile, and reduce LDS. This tends to occur on high sand content soils like golf greens and sports fields.
- Some retain water in the soil for a long time. This reduces the need to irrigate or hand-water as the water is available for longer.
- Improve turf health.
Types of Soil Wetting Agents.
You can group Soil wetters by how they interact with water and the soil structure. Each type addresses a different soil moisture need.
-
Penetrants. These are for hydrophobic sands and areas affected by Localised Dry Spot (LDS). They help water move rapidly through the soil profile and help restore uniform water infiltration.
Examples include HydroForce Ultra, HydroForce Rapid, and Scrubwet. -
Retainers. These hold moisture in the soil for longer periods, and are ideal for drought prone or coarse soils. They reduce the need to irrigate and help turf cope better with heat stress.
Examples include Aquimax and HydroForce Extend. -
Combination or Multi-functional Agents. These are a mix of penetrant and retainer technologies to give balanced infiltration and water retention. They are ideal for high-traffic turf and sports surfaces.
Examples include HydroForce Ultra and Aquaforce.
Uses Beyond Turf.
Soil wetting agents are vital in turf and sports turf management. However, they also improve irrigation efficiency in horticulture and agriculture. In these sectors, surfactants lead to more uniform crop growth and reduce the need to irrigate. They:
- Reduce water loss.
- Improve water movement into dry soils.
- Help nutrients move to plant roots.
How Do Soil Wetting Agents Work?
- In sandy and high organic matter (OM) soils, soil particles can develop a waxy coat that repels water.
- This wax coat makes it hard for roots to access water in the soil.
- Wetting agents are surfactants, and have a hydrophilic (water-loving) and a hydrophobic (water-repellant) end.
- When you use a soil surfactant, the hydrophobic end attaches to the wax coat, and the hydrophilic end interacts with the water.
- This leads to better water movement and distribution in the soil.

Whether you have bentgrass greens or warm season sports grounds, the HydroForce range gives consistent results that you can see.
What Superintendents Say.
Pete Dunn, Superintendent – Federal GC
“HydroForce Ultra is the best I’ve ever seen by a mile. Day three of 35°C and we haven’t had to hand water a single green. We’d skip any irrigation if it weren’t for the surrounds.”
Chris Lynch, Superintendent – Fairbairn GC
“We’ve had better infiltration on heavier soil greens. Water doesnt pool where it used to sit.”
Evidence and Efficacy.
Independent and in-house trials confirm the performance of these soil wetting agents under a range of soil conditions.
-
USGA (2021) study. Wetting agents improve soil moisture uniformity by 27%. They reduce LDS on sand-based greens.
-
Gilba Solutions 2024 internal trials. HydroForce Ultra retained 15% more moisture at 75 mm depth compared to untreated control plots.

Environmental Safety Profile.
-
Biodegradable. The HydroForce range of soil wetting agents comprise surfactants that break down naturally in the soil.
-
Low Toxicity. Being non-ionic formulations they are not phytotoxic and are safe for turf and beneficial soil microbes when you use them as directed.
-
Runoff. They are designed to reduce the runoff of surface water and leaching by managing water infiltration.

Do Soil wetting agents replace irrigation?
No. They complement irrigation. They improve how the water moves and stays in the soil. This reduces waste but does not entirely replace watering.
Can I make my own soil wetter?
Homemade solutions are inconsistent and can damage turf. Professional grade soil wetting agents are chemically balanced to ensure uniform infiltration without any turf damage.
How often should you apply these?
Apply these every 3 to 5 weeks when there is active growth or as part of your irrigation schedule. High-sand content greens and sports turf may need more frequent use.
Are wetting agents safe for lawns?
Yes. Professional-grade wetting agents like HydroForce are non-toxic to turf and soil microbes when you use them at label rates. They are biodegradable and environmentally safe.
