Tom Seifert

Tom Seifert, corn and soybean farmer in Auburn, runs two cover crop test plots to help evaluate how much cover crops can help reduce nitrate leaching into Lake Springfield.

Nitrates that migrate from crop land can end up in rivers, lakes and eventually drinking water, according to Dr. Catherine Zeman, and they can lead to health problems.

Zeman is an environmental health researcher and professor of health promotion in the department of kinesiology, allied health and human services at the University of Northern Iowa.

She will be talking about “Nitrates & Our Health” in a public program set for Thursday, March 21, from 7-8:30 p.m. in Augustana University’s Mikkelson Auditorium.

Zeman received a Ph.D. in preventive medicine from the University of Iowa. She was a Fullbright Scholar focused on environmental health issues, has contributed chapters to numerous books about public and environmental health, and has authored or co-authored more than 30 published articles about nitrates, environmental health and other public health topics.

This program is sponsored by Friends of the Big Sioux River, an organization working to restore and protect healthy water in the Big Sioux River and its tributaries.

Mikkelson Auditorium is located in Augustana’s Froiland Science Center at the corner of 33rd Street and Summit Avenue in Sioux Falls. The program is open to the public, and there is no admission charge.
