Wetting agents and surfactants
Wetting agents for lawns are specific formulations designed to improve water absorption and distribution in the soil. These products reduce the surface tension of water, promoting uniform penetration and preventing the formation of dry spots or inefficient irrigation. Ideal for soils prone to hydrophobic phenomena, wetting agents ensure more efficient irrigation management, optimizing water resource use and promoting healthy, uniform grass growth.

OARS PS
Soil penetrating surfactant
Description
PRODUCT DETAILS
- Provides firm, fast playing surfaces
- Increases penetration of water
- Improves water management efficiency
- Loosens and redistributes hydrophobic soil particles
OARS PS is a soil-penetrating surfactant. It combines the university-researched, field-proven and patented Organic Acid Redistribution System (OARS) with multi-branched penetrant chemistry. OARS PS controls soil water repellency and provides uniform soil moisture for a longer period of time.

Aquifer
Omni directional soil surfactant
Description
PRODUCT DETAILS
- Reduces localised dry spots
- Reduces summer stress and wilt
- Increases water retention
- Uniform moisture soil profile
Aquifer Soil Surfactant is designed to be the first choice when selecting a surfactant. Aquifer produces both downward and lateral (omni-directional) movement of water, providing a uniform moisture profile throughout the soil structure for up to 45 days. This even distribution carries not only water but also chemicals and nutrients throughout the root zone. The result is less summer stress, reduced wilt, fewer localized dry spots and improved rewetting capability.

Aqua Aid
Penetrating wetting agent
Description
PRODUCT DETAILS
- Reduces water usage
- Increases nutrient uptake
- Effective at low rates
Aqua Aid Liquid is a penetrating wetting agent formulated to increase infiltration of water into the soil profile. Applied every 2 to 4 weeks as a treatment for LDS conditions, Aqua Aid Liquid is the most cost effective product on the market.

Dry spot and soil hydrophobicity: why turf dries out in patches
A dry spot (localized dry spot) is a patch of turf that stays dry even when the rest of the surface is irrigated regularly.
The most common cause is soil hydrophobicity: soil particles become coated with waxy organic compounds and start repelling water instead of absorbing it.
Irrigation or rain water slides over the hydrophobic surface, runs off to the surrounding areas or evaporates, and the root zone beneath the patch stays dry.
The problem is most frequent on sandy, free-draining root zones — such as golf greens and sports fields — and gets worse in hot, dry weather.
Applying more water does not solve it: as long as the soil repels water, the extra irrigation is wasted before it reaches the roots.
Wetting agents and soil surfactants reduce the surface tension of water and restore the soil’s ability to absorb and distribute it evenly.
For this purpose Comagricola Green Europe offers the Aqua Aid range of wetting agents, including OARS HS, used in professional turf maintenance.
Frequently asked questions about Surfactants
Wetting agents are formulations that reduce the surface tension of water and improve its absorption and distribution in the soil. Applied to turf, they help irrigation water penetrate evenly instead of running off or sitting on the surface. Comagricola Green Europe offers the Aqua Aid range of wetting agents and soil surfactants for this purpose.
Turf needs a wetting agent when the soil has become hydrophobic, meaning it repels water instead of absorbing it, and dry patches (localized dry spots) appear despite regular irrigation. The problem is most common in hot, dry periods and on free-draining sandy root zones such as golf greens and sports fields. In these conditions a wetting agent restores uniform moisture distribution in the root zone.
A surfactant is the general category of substances that reduce the surface tension of water. A wetting agent is a surfactant formulated specifically to help soil receive and retain moisture evenly. In everyday turf management the two terms are often used interchangeably, and the Comagricola Green Europe page presents them together.
Yes, wetting agents fit into the normal turf irrigation programme and do not replace it. They make the water you already apply more effective, because they help it penetrate and spread evenly through the soil, reducing losses to surface run-off and evaporation. Application methods and timing for each product should be checked on its technical data sheet.
