When crops talk to farmers
June 27th, 2007

A technology developed for NASA to conserve water for plant growth during long-term space flights has been adapted by researchers at the University of Colorado at Boulder (UCB) to serve another purpose. Now, crops can tell farmers they need water. The farmers just need to clip a tiny sensor to their potato or corn leaves. When the plant feels it needs some moisture, data from the leaves will be sent wirelessly over the Internet to computers linked to irrigation equipment. This should save millions of dollars per year in Colorado only, and it will also be eco-friendly by reducing the amounts of water used for irrigation.
