Iowa Nutrient Research Center water quality research seminar series highlights decade of work and impacts

The Iowa Nutrient Research Center will celebrate its 10th anniversary with a new seminar series highlighting outcomes and impacts from a decade of research. The series starts this fall and continues through spring 2023.

Two presenters each month will discuss INRC-supported projects. The presentations will take place the second Wednesday of each month, from 3:10-4 p.m. The fall seminars begin Sept. 14. The hybrid seminar series will be presented online and in-person at 1306 Elings Hall, 605 Bissell Road, on the Iowa State University campus.

“The INRC began its work in 2013, and since that time, we’ve supported more than 115 research projects,” said INRC Director Matt Helmers. “This seminar series aims to provide a sense of the breadth and depth of this work. Although the focus is on the past, the value of these efforts is to help Iowa and the water quality research community prepare for the important work ahead.”

The Iowa Nutrient Research Center was established by the Iowa Board of Regents in response to legislation passed by the Iowa Legislature in 2013. The center pursues science-based approaches to areas that include evaluating the performance of current and emerging nutrient management practices and providing recommendations on implementing the practices and developing new practices. Iowa State leads the partnership that includes the University of Iowa and the University of Northern Iowa.
