Forest Fine Root Litter Mitigates the NH₃ Volatilization and N₂O Emission from N-Applied Agriculture Soil.

ABSTRACT: Forest fine root litter enters agricultural soils in some cases and its decomposition would change the soil's properties. 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 Populus deltoides (RP) and Metasequoia glyptostroboides (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 activit
