Groundwater management area works to improve nitrogen efficiency

Groundwater nitrate levels have been rising since the 1970s in one area of northeast Nebraska. Producers are learning about new tools to help change that.

Tom Krause of Brunswick can't fly, but he can manage his cornfields from the sky by using the drone thermal imaging company called AirScout and a package of Advanced Digital Vegetation Index information.

Krause discussed his improved irrigation efficiency and nitrogen savings at a field stop at his farm during the recent Bazile Groundwater Management Area farm tour. Producers and conservation agency officials looked at telemetry, irrigation scheduling, soil moisture probes, variable-rate irrigation, variable0rate fertilization and biological nitrogen inhibitors as part of the multifarm tour.

Tanner Jenkins from Oshkosh recently took the reigns as coordinator of BGWMA. He emphasized the goals of the project to inform producers about things they can do to reduce nitrogen leaching into the groundwater. "We want to look at new management practices that can improve yield, lower nitrogen and groundwater use, and improve profits," Jenkins says. "Groundwater nitrate levels have been rising in the region since the early 1980s," he explains. The increased nitrates have impacted drinking water supplies in several communities within the project area.

"There has been a steady increase in nitrate levels," says Jenkins. "So if we can inform producers about ways to possibly curb the increases, get them to level off and eventually drop — that is our goal."

It is known that urban residential areas often overwater and overfertilize lawns, because homeowners do not always soil-test or use calibrated equipment to apply fertilizer or water for their landscaping needs. So, BGWMA sponsored an urban lawn and garden tour in July to help urban homeowners learn about methods to lower their own fertilizer and water use, and even consider planting different varieties of grass.

"Every little bit helps," Jenkins says. "The only way we can lower groundwater nitrate levels is to remove more nitrates through growing crops and plant material than we put back into the groundwater," he says. "Right now, I'm looking at programming that can help give producers the tools to do that."

BGWMA covers a region in Knox, Pierce and Antelope counties that encompasses parts of Lewis and Clark Natural Resources District, Lower Elkhorn NRD, Lower Niobrara NRD and Upper Elkhorn NRD. The project is being funded in part through support from Nebraska Environmental Trust and Nebraska Department of Environmental Quality. The area covers 21 townships and 10 communities.

Curt Arens began writing about Nebraska’s farm families when he was in high school. Before joining Farm Progress as a field editor in April 2010, he had worked as a freelance farm writer for 27 years, first for newspapers and then for farm magazines, including Nebraska Farmer.

His real full-time career, however, during that same period was farming his family’s fourth generation land in northeast Nebraska. He also operated his Christmas tree farm and grew black oil sunflowers for wild birdseed. Curt continues to raise corn, soybeans and alfalfa and runs a cow-calf herd.

Curt and his wife Donna have four children, Lauren, Taylor, Zachary and Benjamin. They are active in their church and St. Rose School in Crofton, where Donna teaches and their children attend classes.

Previously, the 1986 University of Nebraska animal science graduate wrote a weekly rural life column, developed a farm radio program and wrote books about farm direct marketing and farmers markets. He received media honors from the Nebraska Forest Service, Center for Rural Affairs and Northeast Nebraska Experimental Farm Association.

He wrote about the spiritual side of farming in his 2008 book, “Down to Earth: Celebrating a Blessed Life on the Land,” garnering a Catholic Press Association award.
