A new study from University of Iowa researchers shows the nitrate flowing from Iowa farm fields is a large part of the total load in the Mississippi and Missouri Rivers.
During this episode of River to River, Ben Kieffer talks with one of the authors of the study, research engineer Chris Jones, about the devastating impact nutrients from Iowa farmland is having downstream.
In the second half of the show, University of Iowa political scientist Bill Reisinger provides some insight on tensions in Eastern Europe, including how Ukraine faked the murder of a journalist allegedly to foil a Russian assassination plot.
