I’m Ray Benson with the University of Arkansas Division of Agriculture. I work with the Mississippi County Extension Service.
Today we’re going to set up a surge valve demonstration on a producer’s field in Osceola. [Ray removes the valve from the pickup truck.] When the surge valve comes in, you order either 8, 10 or 12 inch surge valve. A surge valve is simply a "t" with a butterfly valve that will switch water flow from one side to the other. So it oscillates from one side of the field to the other.
All the surge valves come with a control panel which is solar powered to keep the battery charged. And has an electric motor with a drive. [Ray shows the solar control panel.] We just place these on the surge valve, the sun keeps the battery charged and then based on the time we set it to irrigate the field, the motor turns and moves this butterfly valve inside the surge valve to water from one side or the other.
That’s all it takes to assemble the surge valve with the control panel. Once we get to the field, we will set the irrigation time with this advance setting. The advance setting is just simply the number of hours it takes to water the end of the field. [Ray screws the control panel to the top of the valve. Ray shows the panel that has the control setting knobs and switches.]
Soak is once the irrigation cycle is over, it oscillates back and forth very quickly, every hour or so to keep the field wet enough that the soil moisture or the water soaks into the soil profile, but not enough irrigation that it continues to run off into the ditch or off into the field. [Video shows Ray connecting the valve to the pipe. After it is connected the water if flowing into the field.]
If you would like more information about surge valves or any of our irrigation projects, you can contact the local extension office or you can visit www.uaex.edu on the web and get information where to order surge valves or how to set those up.
