In hydrophobic soils, soil wetting agents work by countering hydrophobicity while in saturated soils, wetting agents can help to increase water movement through the soil profile. This results in a decrease in water use improved water efficiency and a more consistent playing surface.

In a wetting agent survey in 2004, wetting agents use was for four reasons:

  • Relieving localized dry spots (42%);
  • Managing water (32%);
  • Improving drainage (11%) and
  • Improving pesticide movement into the soil (9%).

What is a soil wetting agent?

The definition of a wetting agent for soil is “Any compound that causes a liquid to spread more easily across or penetrate the surface of a solid by reducing the surface tension of the liquid.”

Managing sand-based rootzones can be challenging particularly during dry, hot conditions, and hydrophobicity can result in ‘hot spots’ that tend to dry out faster compared to other turf areas.

A common question we are asked is “What is the best wetting agent?” and after years of experience, we can say that the new Indigo Hydroforce range developed by RhizoSolutions is the best on the market.

The reason for this is simple. The Indigo Hydroforce® range has been researched by some of the world’s most renowned Universities and has been proven to work under all field conditions. They simply are the best soil wetting agents in Australia. Use of the Hydroforce® range:

  • Promotes healthy turf as water and chemicals penetrate deeper and more uniformly into the root zone;
  • Ensures uniform water distribution through the rootzone, and consequently encourages a deeper root structure, subsequently meaning healthier, denser, and more uniform turf surfaces;
  • Saves water because there is less loss to run-off or surface evaporation;
  • Increases root mass;
  • Reduces turf diseases such as dollar spot and lastly
  • Improves turf health.


Pete Dunn, Course Superintendent at Federal G.C.

‘Mate that HydroForce Ultra wetting agent is the best product I’ve ever seen by a mile. On the third day at 35°C and we haven’t had to put any hand watering on the greens. We wouldn’t even irrigate if it wasn’t for the surrounds drying out.’…

Dave Ramage the Course Superintendent at Fairbairn GC.

‘Yes, good results so far improved infiltration on some of the heavier soil greens with no water pooling in areas that had before.’…

Don’t be fooled by marketing. This gear is proven!
