At West Campus of ASU, CAP researchers are currently testing the use of a polymer developed and used in California that gets injected into turf soils to help retain water and reduce irrigation needs. It’s the first test of that polymer in Arizona (truly arid desert compared to where it was developed). It’s a project with the University Sustainability Practices & Bureau of Reclamations. “Installation1” is the equipment the company used to inject the polymer.

Soil moisture dynamics were modeled using soil moisture data from the long term experimental landscapes at our North Desert Village experimental neighborhood. The relationship between irrigation schedules and plant stress differed by landscape type, which has implications for optimal irrigation regimes.
