Report Highlights Progress and Long-Term Challenges of Iowa Stream Nutrient Monitoring

December 21, 2016

A 2016 report of Iowa’s water monitoring efforts for nutrients highlights both the complexity and long-term value of evaluating nutrient levels in Iowa’s lakes, streams and rivers. Developed jointly by the Iowa Department of Agriculture and Land Stewardship and Iowa Department of Natural Resources, with the support of Iowa State University and the University of Iowa IIHR—Hydroscience and Engineering Center, the report is the first of its kind in Iowa and includes a comprehensive list of surface water monitoring efforts specific to nutrients.

Iowa State University Researcher Seeks Greater Understanding of Nutrient Cycling to Increase Productivity in Agricultural Systems

Iowa State University, department of agronomy professor Michael CastellanoAMES, Iowa — As an undergraduate, Michael Castellano spent one summer on a New Mexico ranch doing environmental science research. He was inspired by the landowner’s implementation of a grass banking system.

Eleven land-grant institutions work across state lines to reduce water contaminants

April 26, 2016

Eleven land-grant institutions and partner organizations are working together to improve farm drainage in order to reduce the contamination of surrounding land and water. The underground drainage systems that channel water off of fields are also prone to diverting crop fertilizers and pesticides. In 2009, researchers formed the “Project NCERA-217: Drainage Design and Management Practices to Improve Water Quality.”

Iowa State University researchers gain understanding of the winter rye-cover crops yield problem

March 14, 2016

AMES, Iowa — Cover crops offer a valuable tool for farmers to reduce nutrient loss and help ensure clean water in Iowa waterways. But some farmers have reported that planting winter rye as a cover crop may reduce corn yield.

A team of researchers at Iowa State University is investigating why there may be an occasional decrease in corn yield after planting winter rye.

Iowa Nutrient Research Center funds third year of water quality-related projects

December 10, 2015

The Iowa Nutrient Research Center at Iowa State University has funded 11 new projects related to water quality.

Researchers from Iowa State, the University of Iowa and the University of Northern Iowa will collaborate on the projects with those from the U.S. Department of Agriculture, Iowa Department of Natural Resources, the Iowa Soybean Association, The Nature Conservancy and AgSolver Inc. This is the third year the center has funded research.
