If you want to improve the water management for your turf rootzones, one of the most important tools are wetting agents.
Wetting agents are used to:
Wetting agents are surfactants. Surfactants have a hydrophilic “water-loving”, and a hydrophobic “water-fearing” part.
Different active ingredients with different ratios of hydrophilic and hydrophobic characteristics are combined to achieve the desired results.
Depending on the combination of surfactants in the product and how they work in the soil, they are sometimes referred to as either retaining or penetrating wetting agents.
The surfactants in wetting agents can:
There is no one fits it all. Environmental conditions, the soil moisture levels, and the soils are different.
You can choose the right wetting agent depending on the intended use:
Turf that is exposed to drought becomes more susceptible to diseases when its energy reserves are depleted. For optimal root growth as well as optimal development and stress tolerance of the lawn plant, it is necessary that the roots receive sufficient oxygen. Therefore, it is essential to create a balance of sand particles, water and air in the root area.
It is resistant to microbial decomposition even under adverse environmental conditions with sustained temperatures above 20 °C.
Start with a wetting agent program with the recommended application rate before the soil goes hydrophobic. It is best to prepare turf in good time for a dry period. This might usually be end of April.
For some years, we worked on developing an organic wetting agent that is approved in organic farming. A huge variety of different raw materials have been tested.
After 3 years of research, TourTurf® REO Respond® Extreme Organic Wetting Agent is now on the marked and shows high potential. Its performance is very close to its synthetic counterpart, TourTurf® ELL Respond® Extreme Long Lasting.
During a trial, TourTurf® REO showed a reduction of water evaporation of 10% in comparison to 12% of the leading product TourTurf® ELL.
See the difference the product makes in evaporation:
The plants benefit greatly under stress conditions.
The changes in water availability and more frequent weather extremes make it necessary to use available irrigation water as efficient as possible on those large areas. Every Drop Matters!
TourTurf® EFE Respond® Extreme Fairway ECO can be mixed with iron and seaweed products.
In both cases, there is already a problem with hydrophobic conditions.
Localized Dry Spot (LDS) is not a pathogen affecting the grass. There is just not enough water in the soil to keep the grass green because of the water-repellent wax coating that has developed on the soil particles because of fungal activity in the soil. This wax layer can be formed by organic decomposition products that are produced during the decomposition of thatch.
LDS appears mostly on sand based rootzones and is more severe when there is a thatch problem. The irrigation settings used to make the greens as firm and fast as possible can contribute to the development of this problem.
If there is a problem with fairy rings, the Basidiomycota feeding on the thatch layer make the soil water-repellent. In all those cases, applications of TourTurf® EXC Respond® Extreme Curative in connection with thatch management, aerification, and optimisation of irrigation will help to reduce the problem.
Grasses like Festuca and Agrostis on golf greens and Poa pratensis on soccer fields are capable of developing a larger and deeper root system.
TourTurf® FTE Respond® Extreme Fine Turf Enhancer gives them an advantage over shallow rooting Poa annua, considered a weed on many playing surfaces.
Thanks to TourTurf® EPT Respond® Extreme Penetrator water easily penetrates the soil and in the case of extreme soil moisture, water is drained out of the soil profile.
This function is especially useful for high-profile soccer pitches with that get a lot of play outside the vegetation period. Excess water must be drained out of the rootzone as soon as possible to minimize mechanical damage to the pitch.
If the surface tension of the water is reduced, dew can easily run off the leaves and penetrate the soil profile.
A drier leaf keeps the plant healthy, especially in times of the year when it is under attack from Dollar Spot.
During the autumn months and into the winter, the plant greatly benefits if the leaves are as dry as possible. The sticker keeps the product on the leaves.
It is important to apply TourTurf® EDC Respond® Extreme Dew Control when the leaves are as dry as possible to get it to stick to the plant. It will be removed by cutting or heavy rainfall and will have to be reapplied regularly.
