Managing Nitrogen to Reduce Losses as Nitrous Oxide

September 18, 2017
Nitrogen is a key factor in farm management and economics. One of the most expensive inputs for corn production, it can be easily lost to the environment. One avenue for losing N, as nitrous oxide, has an impact on our climate as a greenhouse gas. Successful strategies for reducing N losses, especially as nitrous oxide, benefit both farmers and the environment.
