Abstract: Results from an irrigator survey in southern Alberta (Canada) indicate that more than half of irrigators changed irrigation technologies during the five-year period (crop years 2007/08-2011/12) and this potentially improved application efficiency. Changes were made from flood irrigation to wheel-move sprinklers to high- and then low-pressure pivot systems. The intended future rate of change is lower than that experienced over the previous five years. Important factors causing these changes were identified: reducing irrigation application, labour and energy inputs, and increasing crop yields and quality. Econometric modelling shows that irrigators who have commenced the process of adopting more efficient sprinklers are full-time farmers, operate their farm as corporations or partnerships, obtain information from extension agencies, and are more likely to upgrade their technologies in future.
