“We are a close and dynamic industry. Irrigation educators and practitioners are hungry for innovative ideas and technology that can be brought to bear affordably. That’s what drew me to ASIC in the 1980s – steadfast commitment to exploring and sharing irrigation innovation. The Society has always directed an unblinking focus on water conservation and unbiased, third-party support to clientele.”

– Stephen Smith, PhD, FASIC
