Researchers find losses of nutrients, greenhouse gases from poorly drained depressions higher than predicted

February 11, 2021

AMES, Iowa — With the help of an innovative new monitoring system, Iowa State researchers looking at nitrogen and phosphorus losses to water and the atmosphere are able to pinpoint nutrient fluxes better than many previous studies. In the process, they are refining knowledge of where – and when -- to expect nutrient-loss hot spots.  Read more about Researchers find losses of nutrients, greenhouse gases from poorly drained depressions higher than predicted

Soil study shows why nitrous oxide emissions should factor into climate change mitigation

November 11, 2021

A newly published study found that poorly drained agricultural soils emit enough of the greenhouse gas nitrous oxide that the resulting climate change effects could far exceed the benefits of using the same soils as a means of sequestering carbon.The research, published in the Proceedings of the National Academy of Sciences, was authored by Steven Hall, associate professor of ecology, evolution and organismal biology; Nathaniel Lawrence, ISU graduate student in ecology, evolution and organismal biology; Carlos Tenesaca, research scientist in ecology, evolution and organismal biology; and Andy VanLoocke, associate professor of agronomy. Funders for the work included the Iowa Nutrient Research Center.  Read more about Soil study shows why nitrous oxide emissions should factor into climate change mitigation
