OARS HS is a soil hydrating surfactant. This unique product is a combination of the university researched, field proven, and patented organic acid redistribution system and multi-branched hydrating chemistry. OARS HS controls soil water repellency while providing uniform soil moisture and increased soil moisture retention.

Product Details

  • Increases number of hydrating sites
  • Multi-branched hydrating soil surfactant
  • Increased length of activity in soil
  • Loosens and redistributes humic coatings from hydrophobic soil particles

Application Rates

Apply 13-16 L of OARS HS per hectare every 30 days. After an initial 16 L application, drought conditions can be best managed by applying 6-8 L per hectare every 15 days.

​For extreme drought conditions with high temperatures and/or increased soil water repellency, apply 20-25 L of OARS HS per hectare every 30 days.

Aqua Aid Europe offers an extensive range of surfactant products for the professional turf industry. These surfactants can be split up into two major categories, state-of-the-art 3-D surfactants and conventional surfactants. The 3-D surfactants are the most advanced surfactants in the market. These surfactants are backed up with various independent research and have field-proven results for numerous of years by the end users.

The multi-branch regenerating technology is completely different to other technologies currently used in the professional turf market. The difference between the traditional linear co-polymer molecules is that they are much higher in molecular weight and have multiple interactive sites (6 or 8 sites), therefore each branch is a wetting agent by itself. This branching will increase the interaction between the surfactant and the soil, causing very consistent moisture levels within the treated surface. The combination of the higher molecule weight and branching will positively affect the biodegradation of the product. As one branch is removed via biodegradation, a new lower molecular weight surface active species is regenerated, which will continue to manage the water in the soil.

This technology is incorporated in all of our 3-D surfactants reducing hydrophobic conditions on a sustainable basis.
Independent research has shown the surfactants are able to reduce water use of over 30 % while keeping a consistent turf quality.
