New Irrigation Technology Could Save Water for Arizona Farms
The Central Arizona Project, which delivers Colorado River water to more than 80% of Arizona’s growing population, is taking a three-pronged approach to the megadrought that has resulted in the first water cutbacks to Arizona farmers.
One of those approaches is N-Drip, which converts flood-irrigated fields into a drip system that uses gravity, with no external form of energy. Developed by an Israeli company, the system is being tested to grow sorghum in Australia, sugar cane in Thailand and now cotton and alfalfa in Arizona.
