Wetting Agents

During periods of dry weather, the soil on which your lawn is situated can become so dry that it becomes water-repellent, and is therefore unable to effectively disperse water through the soil profile.

Hydrophobic soil causes pooling of surface water, which can be counterproductive as the water needs to get to the soil in order to benefit the grass plant.

Wetting agents have been used extensively in the sports turf sector for many years, as such large areas of golf courses and sports pitches require a large amount of watering during periods of dry weather. The potential cost savings of applying wetting agents can therefore be significant on large turfed areas, as far less water will be required to keep the grass healthy and hydrated.

Our franchisees have applied wetting agents at various sports venues during their background careers as greenkeepers and grounds care professionals.

Dry Patch

Dry Patch is a common occurrence as a result of hydrophobic soil. The grass will appear dead in patches as the plant is depleted of water. A waxy layer of white mycelium fungus is created which makes the soil hydrophobic. This waxy layer repels water, preventing water penetration.

How do Wetting Agents Work?

Wetting agents act as a soil penetrant by reducing the surface tension of water to promote quick water infiltration and penetration deep into the soil profile. This means that when you do water your lawn, it will be better absorbed, therefore allowing the grass plant to utilise it properly. This in effect will help stop your lawn drying out as easily.

The retention of water is longer through the use of the wetting agents, which therefore reduces the overall amount of watering required.

Benefits of Wetting Agents

  • Improves surface water penetration and reduces pooling of surface water.
  • Improves root development.
  • Penetration depth of 25cm – 30cm achieved within 30 minutes of application.
  • Does not need watering in after application.
  • Improves oxygen flow to the soil profile.
  • Reduces watering input required in dry periods.
  • Can be applied in conjunction with other lawn treatments.
