Iowa State Scientists Team Up to Keep Nitrates on Fields

Scientists from Iowa State University are researching how to prevent the runoff of nitrogen from fields into bodies of water. Too much nitrogen runoff becomes a big problem, both ecologically and in terms of human health. One way they have found to reduce nitrogen runoff is the use of cover crops, which “can hold nitrogen in the soil.” The scientists also make note of the broader issues nitrogen runoff relates to, such as how managing it could affect agricultural economies. Solutions will continue to be studied, especially in relation to affordability for farmers.
