Farmers can help to combat climate change by applying more precise amounts of nitrogen fertilizer to fields, according to a recent study by researchers at Michigan State University.

The study – published in this week’s Proceedings of the National Academy of Sciences – used data from around the world to conclude that emissions from nitrogen oxide – a byproduct of nitrogen fertilizer – contribute to greenhouse gases more than previously expected when application of fertilizer exceeds crop needs. Nitrogen emissions caused by humans has increased significantly in recent years much of what can be attributed to increased nitrogen fertilizer use. Not only will more precise amounts of fertilizer protect the environment but it will also help to save farmers money.
