A farmer near Sioux City has turned to solar energy to power his irrigation system, according to a report from the Sioux City Journal.

Dolf Ivener recently designed a center pivot irrigation system that runs on a 22-panel solar array in his farm near Whiting, Iowa. The solar panels produce enough power to propel the system around the field while spraying water or fertilizer through its pipes.

While heavy rain and record flooding in the Sioux City area earlier this summer prevented Ivener from getting the most out of his system, he expects the innovation to pay off over the next ten years. Nearly half the cost of installing the solar panels was covered by federal and state grants designed to encourage solar energy use.

The agriculture industry has led the way in solar energy applications, according to the United States Department of Agriculture. Farmers in remote areas were some of the first to turn to solar energy as an alternative to kerosene, diesel and propane when grid connections were unavailable. A switch to renewable energy sources like solar could drastically reduce carbon emissions from farms.
