New research supported by the Iowa Nutrient Research Center suggests that water quality challenges would be even greater if it weren’t for a little appreciated feature of the landscape: road ditches.
More landowners are interested in planting strips of deep-rooted prairie within crop fields or on marginal land as an effective soil conservation and water quality practice. But they need reliable answers about the costs and benefits.
The Iowa Nutrient Research Center at Iowa State University is seeking new proposals for water-quality research that can help landowners reduce nitrate and phosphorus in the state’s waterways, one of Iowa’s most pressing concerns. The center will begin accepting proposals this week for its ne
On a cold day last fall, Iowa State University scientist Michelle Soupir and her team of graduate students shoveled out the woodchip-and-mud entrails of nine concrete-lined water-quality cells at the Agricultural Engineering and Agronomy Research Farm near Ames. They packed samples from the cells — mini-bioreactors — into plastic bags and labeled them to take back to the lab, where they would measure bacterial activity and the rate of woodchip decomposition.
A new technology for cleansing nutrients from water leaving Iowa’s tile-drained fields began with two Iowa State University researchers brainstorming after a professional meeting.
“If farmers have a good year growing cover crops, they can get really excited and plant more acres.
The Iowa Nutrient Research Center at Iowa State University has funded 16 new water quality and nutrient management projects for 2018-19.
AMES, Iowa — An Iowa State University professor of agricultural and biosystems engineering has been named the new director of the
