SIOUX CENTER, Iowa (AP) — A research project in northwest Iowa is looking at ways to keep fertilizer out of drinking water by planting certain crops to help contain nitrogen.
The Sioux City Journal reports (http://bit.ly/1jCxgXv ) the project on Matt Schuiteman's land near Sioux Center yielded lessons that may be useful in other areas.
The research got started because some of Schuiteman's land is close to wells Sioux Center relies on for drinking water, and nitrate levels were rising.
The project looked at five different ways to use perennials and cover crops to limit the amount of nitrogen that washed away.
Schuiteman says he plans to start growing alfalfa on his land in rotation with corn because that proved effective.
