Water management with Screen™

Screen reflects harmful UV, IR, and excess visible light that results in higher leaf and canopy temperatures. Cooler crops use less water for transpiration. An application of Screen can reduce potential water use up to 40%.  Plant physiologists use the following formula to estimate crop water usage:

 

Potential Water Use =       Net Radiation(UV, visible, IR) 

                                            1 + Bowen Ratio (∆Temperature,Humidity)

The Bowen Ratio is based upon the difference in temperature and humidity between the leaf and the air. As temperature drops, the number increases.

 

Screen can reduce net radiation by 25-30%, and leaf temperatures by up to 8°C. This predicts a reduction in net water use of 35-40%.

 

Numerous studies from California, Australia, South Africa, and other dry locations have shown improved water status (leaf water potential) in almonds, citrus, wine grapes, and other crops from particle film applications. Screen is an excellent tool for reducing water usage. A Screen film can mean the difference between a quality crop and poor crop, or even no crop at all. For trial results and reports #click here.
