Shifting from flood-irrigation to more efficient systems is the focus of a cotton field trial currently underway at the U.S. Arid-Land Agriculture Research Center in Maricopa, Arizona.

According to an article in the Western Farm Press, the project includes a Zimmatic linear move sprinkler system with six spans and an overhang along with a retrofitted variable rate irrigation system. The system is managed using precision agriculture tools to provide timely, variable applications across the field, including remote sensing, computer modeling and other tools.

“VRI allows us to manage the field so we can explicitly show how cotton responds to different water rates and timings from June through August,” researcher Kelly Thorp told the Western Farm Press.
