Surfactants III. Success stories

Surfactants have proven effective in the removal of organic acids from soil colloids and in the ability to bind water molecules to soil particles, resulting in a better distribution of water throughout the soil. soil profile and the prevention of the occurrence of hydrophobic zones.

There are many success stories in the use of surfactantsFor example, we can highlight the uses in the following areas Quilchena Golf Country Clubwhere it was applied to golf fairways with the aim of increasing irrigation efficiency, improving the quality of the grass and reducing water consumption.

The results obtained were really satisfactory, leading to a decrease in water expenditure by 10% in the first year and another 10% in the following year. (USGA "The benefits of wetting agents and effective communication", 2016).

There are recorded studies of the decrease of hydrophobic organic films on sand particles after repeated use of certain surfactants (Annual report on USGA ID: 2014-09-498, Xi Xiong, Stephen H. Anderson, et al. 2016).

Further studies are being carried out to determine whether the combined use of thermal blankets and wetting agents could reduce the damage to greens bermuda as "Tifeagle" o "Mini-green", due to crown desiccation and low temperatures in those latitudes with cold winters (Michael D. Richardson, Douglas E. Karcher and Eric J. University of Arkansas).

This case resulted in increased greening for all varieties, especially for "...".Tifeagle" y "miniverde“.

Studies have shown that parameters such as the firmness of the greens are strongly correlated with the VWC and the content in organic matter. The effect of wetting agents on the playability of the sports surfaces varies widely and it is other factors such as different soil profile types, organic matter management and post-application of sprinkler irrigation volumes that have the greatest effect on the management of crop firmness. greens (Edward Nangle, PhD, Ohio State University).

Finally, studies such as the influence on the reduction of disease impacts of the Anthracnose are also currently being evaluated in relation to the application of wetting agents (Clint Mattox, Alexander R. Kowalewski, et al. 2016 "Reducing Anthracnose on Poa Annua Putting Green with frequent applications of a soil Surfactant").
