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

Read the full story from Iowa State University.

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, according to a recently published scientific study.

The study, published Monday in the academic journalĀ Proceedings of the National Academy of Sciences, found that a range of agricultural soils produce nitrous oxide emissions in quantities big enough to contribute to climate change. The researchers compared soils with various moisture content and found agricultural soils are capable of high nitrous oxide emissions across a wide range of environmental conditions.
