4-Year Evaluation of Soil Moisture-Based On-Demand Irrigation Controllers Final Report

Research by Michael D. Dukes, Bernard Cardenas-Lailhacar, Grady L. Miller of University of Florida and North Carolina State University.

“. . . only the AC system showed water savings (61%) compared to the control treatment. The systems from brands BL and LL, applied almost the same amount than the control (2% less and 1% more water), and the IM system applied 129% more water than the control treatment.” p. 60 “Only the Acclima SMS system appears to be operative under these conditions; meaning that it could fully automate an irrigation system, without need for human intervention for monthly or seasonally rescheduling of the irrigation cycles.” p. 61

The study spanned four years.
