Invention Allows Thirsty Crops to Signal Farmers

Corn and potato crops may soon provide information to farmers about when they need water and how much should be delivered, thanks to a University of Colorado at Boulder invention optioned to AgriHouse, a Berthoud, Colorado, high-tech company. The technology includes a tiny sensor that can be clipped to plant leaves charting their thickness, a key measure of water deficiency and accompanying stress, said Research Associate Hans-Dieter Seelig of CU-Boulder’s BioServe Space Technology Centre. Data from the leaves could be sent wirelessly over the Internet to computers linked to irrigation equipment, ensuring timely watering, cutting down on excessive water and energy use and potentially saving farmers in Colorado millions of dollars per year — via denverpost.com
