Using Drones To Help Save An Endangered River

Farmers Are Using Drones To Help Save An Endangered River In US

USA Today reports that a drone soared over a blazing hot cornfield in northeastern Colorado on a recent morning, snapping images with an infrared camera to help researchers decide how much water they would give the crops the next day.

After a brief, snaking flight above the field, the drone landed and the researchers removed a handful of memory cards. Back at their computers, they analyzed the images for signs the corn was stressed from a lack of water.

This Department of Agriculture station outside Greeley and other sites across the Southwest are experimenting with drones, specialized cameras and other technology to squeeze the most out of every drop of water in the Colorado River – a vital but beleaguered waterway that serves an estimated 40 million people.

Remote sensors measure soil moisture and relay the readings by Wi-Fi. Cellphone apps collect data from agricultural weather stations and calculate how much water different crops are consuming. Researchers deliberately cut back on water for some crops, trying to get the best harvest with the least amount of moisture – a practice called deficit irrigation.

In the future, tiny needles attached to plants could directly measure how much water they contain and signal irrigation systems to automatically switch on or off.

“It’s like almost every month somebody’s coming up with something here and there,” said Don Ackley, water management supervisor for the Coachella Valley Water District in Southern California. “You almost can’t keep up with it.”

Researchers and farmers are running similar experiments in arid regions around the world. Continue reading about farmers using drones to help save Colorado River.
