However, how this process further influences the ammonia (NH₃) volatilization and nitrous oxide (N₂O) emission from agricultural soil receiving fertilizer nitrogen (N) is unknown. Here, we conducted a soil pot experiment to investigate the responses of the aforementioned gaseous N losses during wheat season to fine root litters derived from <i>Populus deltoides</i> (RP) and <i>Metasequoia glyptostroboides</i> (RM) incorporations. The results showed that two forest fine root litters reduced total NH₃ losses by 30.6-31.9% from 180 kg N ha^-1 applied to farmland soil, and this effect was attributed to decreased soil urease activitPlants (Basel, Switzerland)Forest Fine Root Litter Mitigates the NH&lt;sub&gt;3&lt;/sub&gt; Volatilization and N&lt;sub&gt;2&lt;/sub&gt;O Emission from N-Applied Agriculture Soil.PMC12788022BK2024189632372101BE2022305KYCX25_1357Ning LWu SZhu GChu LfalseForest Fine Root Litter Mitigates the NH&lt;sub&gt;3&lt;/sub&gt; Volatilization and N&lt;sub&gt;2&lt;/sub&gt;O Emission from N-Applied Agriculture Soil.Forest fine root litter enters agricultural soils in some cases and its decomposition would change the soil's properties.
