Experts in fields from agriculture, energy and environment, higher education and healthcare gathered in Cedar Rapids for The Gazette’s Iowa Ideas Conference September 21 and 22.
The two day conference was presented as an opportunity “to connect with fellow Iowans and develop solutions for key issues facing our state.”
Dr. Chris Jones, a University of Iowa researcher and CGRER member proposed one solution that would reduce nitrate runoff in Iowa’s waterways by 10 to 20 percent within one year. The IIHR-Hydroscience and Engineering research engineer stated that Iowa farmers should avoid planting crops on flood plains and stop tilling their land in the fall because it makes soil more susceptible to erosion if they want to see a reduction in nutrient runoff.
According to a report in The Gazette, Jones said, “It’s difficult for me to understand why these things continue. If we could do those two things, we would have a 10 to 20 percent reduction in one year.”
The Iowa Department of Natural Resources reports that there has been a 6 million acre increase in no-till farmland since 1987.
Chris Jones further discusses the science behind nitrate pollution and what it means for Iowa’s natural resources in episode one of Iowa Environmental Focus’ Nitrate Series.
