The farm is designed to compare the effectiveness of three different applicators at 30- and 60-​inch spacing. The applicators include Dragon-​Line, iWob, and bubblers which were installed separately on three spans.

The farm uses groundwater as well as surface water from the Arkansas River that is known for its poor water quality, particularly for salinity issues. Water meter and control panel telemetry has been installed in the center pivot. AquaSpy soil water sensors have been installed on each span with different applicator. The field has been mapped to identify management zones and locate where the soil water sensors could be most effective. The entire field was planted in circular rows in 2018.

This 3-​in-​1 Event (Water Technology Farm Field Day, OAP Center Pivot Irrigation Field Day, Soil Sensor Demonstration Day) includes Free Lunch.
