Technical Program

Past Irrigation Show attendees report that one of the main reasons they come back year after year is to learn about the latest irrigation technologies and innovations. The 2018 technical program presented the latest cutting-edge research covering a variety of irrigation topics. Industry experts presented case studies and research findings on innovations in agriculture and landscape irrigation.

Participants earned 0.33 CEUs for each 20-minute presentation. The sessions were open to all attendees with a full registration.
