On episode three of EnvIowa, we sit down with Dr. Chris Jones, IIHR Research Engineer, to discuss his recent research, which looks at the effects of soybean crops on water quality in Iowa. Much of the research over the last 40 years has been focused on corn, given that corn plants require more fertilizer than soybean plants. However, studies in 2009 and 2016, both of which Dr. Jones co-authored, suggest that soybeans play a larger role than previously understood.

Dr. Jones helps us understand why nutrient pollution has increased steadily as more and more farmers have integrated soybeans into crop rotation, replacing smaller grains and cover-crops, and what it will take to turn this science into water quality policies that benefit Iowans.
