Mitigating Infrared Radiation Impacts is Critical
Posted on July 18, 2012
Turfgrass controls the loss of water from its leaves (i.e., transpiration) by varying the aperture of its stomates (like a tap). Transpiration is important because it keeps the stomates open so that exchange of gases (letting carbon dioxide in and oxygen out) can take place during the photosynthetic process. When excessive heat causes a plant’s stoma to close, it restricts the flow of water vapor out of its leaf. It also causes the reduction of CO2 flowing into the leaf for photosynthesis. This is known as the transpiration compromise or the plant version of “there are no free lunches.”
It has been well documented in the literature that Infrared wavelengths are responsible for much of the heating within plant leaves. Independent testing of Turf Screen, confirmed with field testing reported by several superintendents, has shown that Turf Screen can lower turfgrass’ canopy and soil temperatures. This is accomplished by Turf Screen’s ability to scatter and reflect IR radiation.
An example of Turf Screen’s ability to reduce canopy temperatures was recently reported by Jason Harrison, Superintendent at Worcester Country Club (he has been using Turf Screen for the last 3 years):
I have seen canopy temperature reduction as much as 8 degrees but average around 4.5 degrees”
That may not sound like much but even small changes in turfgrass’ temperature can be significant because in heat stress conditions slight changes in temperature can trigger big changes in a plant’s transpiration rate. Long distance runners know that they can run faster if the temperature is a few degrees lower. Your field crew can work more efficiently when it’s just a bit cooler. Likewise, keeping your turf a few degrees cooler in the middle of a heat wave may make the difference between grass survival and catastrophe.
Turf Screen’s ability to mitigate the damages of both IR and UV radiation give it a great one-two punch that’s unique in the industry.”
Turf Screen’s ingredients of titanium dioxide, zinc oxide, and green pigment combine to scatter and reflect Infrared (IR) radiation, which results in a cooler plant, cooler soil, and better turf quality.
