Seidenberger uses global positioning technology to install drip irrigation systems, too. “All my drip tape except the first 45 acres was installedwith the RTK system. We still use that system when we work that field, but we have to adjust for it.”

He uses ECO Drip for subsurface drip irrigation materials and Netafim tape and filters.

He relies on GPS for more than just installing drip tape. “If the RTK goes down while I’m planting a drip-irrigated field, I shut down. We have to be exactly on the row when we pick six rows at a time.  It also helps to water precisely when you are right on the tapes.”

Some of Seidenberger’s tape is spaced 80 inches between rows and some is on 40-inch spacing under the row.

“If I were doing it all over, I’d put it all 40 inches under the row. That spacing takes about half as much water and gets moisture to the top easier. I could farm flat with the narrow spaces. But the 40-inch tape spacing is quite a bit more expensive to install because there is more drip tape in the fields.”
