Abstract
Abstract Agricultural fields are an important anthropogenic source of atmospheric nitrous oxide (N 2 O) and nitric oxide (NO). Although many field studies have tested the effectiveness of possible mitigation options on N 2 O and NO emissions, the effectiveness of each option varies across sites due to environmental factors and field management. To combine these results and evaluate the overall effectiveness of enhanced‐efficiency fertilizers [i.e., nitrification inhibitors (NIs), polymer‐coated fertilizers (PCFs), and urease inhibitors (UIs)] on N 2 O and NO emissions, we performed a meta‐analysis using field experiment data (113 datasets from 35 studies) published in peer‐reviewed journals through 2008.
