An evaluation of the N<sub>2</sub>O emission reduction potential of enhanced efficiency nitrogen fertilizers and application timing in a semi-arid cereal cropping system. [PDF]

open access: yesJ Environ Qual
Abstract Efforts to cut fertilizer‐related nitrous oxide (N2O) emissions require sustainable nitrogen (N) management that maintains crop productivity while reducing emissions. Technologies such as enhanced efficiency N fertilizers (EENFs) have potential to support best management practices by improving N use efficiency and lowering N2O emissions.
