“I realized what we were doing and the situation that we are in required us to either give up one irrigated circle or find a more efficient means of irrigating. I found that with the LEPA bubbler system allowed us to apply the water we have available in a more productive way. The water that is being applied is resulting in less surface moisture and more beneficial subsoil moisture, this should be all producers goal.”
Bob Holloway’s farm is in a low gallonage area of Kansas, south of Colby and west of Mingo. He irrigates with well water fed from the Ogallala aquifer. In this area, the water table is dropping by about a foot to a foot and half each year, although this year they did receive more rain. Due to water availability, most farms in this area are only able farm corn in half fields – growing half circles of wheat and corn – on 120-acre field.
Bob’s dealer in Colby, Kansas helped him modify his irrigation installation converting to close spacing sprinklers with shrouds and bubbler pads. He used 90” spacing on the first two spans, 60” on the next two spans and then switched the three remaining spans to 39” spacing. With field slop of about 0.5%, he mounted the bubblers at about 8” to 18” off the ground.
Recognizing there are various factors impacting the season end yield results on a farm, Bob feels the change to his irrigation set-up has contributed to the success he is seeing. Bob has been able to farm 50% more corn (a total of 120 acres) with just 250-300 gpm.
