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\u221231.9% from 180 kg N ha\u22121 applied to farmland soil, and this effect was attributed to decreased soil urease activity and ammonium-N during the basal N fertilization period. Whether receiving fertilizer N or not, N2O emissions from farmland soil were significantly (p &lt; 0.05) mitigated by 62.8\u201368.2% and 43.0\u221250.0% following the RP and RM incorporation, respectively. Lower N2O emission was ascribed to increased soil pH but decreased soil nitrate-N and bulk density. In addition, less AOA and AOB amoA but more nosZ gene abundances explained the fine root litter-induced N2O mitigation effect. Neither forest fine root litter exerted a negative effect on wheat grain yield and crop N use efficiency in N-added agriculture soil. In conclusion, forest fine root litter incorporation could help to mitigate gaseous N losses via NH3 volatilization and N2O emission from fertilizer-N-applied agricultural soils, and without crop production loss.<\/jats:p>","DOI":"10.3390\/plants15010057","type":"journal-article","created":{"date-parts":[[2025,12,24]],"date-time":"2025-12-24T11:22:14Z","timestamp":1766575334000},"page":"57","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Forest Fine Root Litter Mitigates the NH3 Volatilization and N2O Emission from N-Applied Agriculture Soil"],"prefix":"10.3390","volume":"15","author":[{"given":"Si","family":"Wu","sequence":"first","affiliation":[{"name":"Co-Innovation Center for Sustainable Forestry in Southern China, College of Forestry and Grassland, Nanjing Forestry University, Nanjing 210037, China"},{"name":"Maize Research Centre, Jiangsu Academy of Agricultural Sciences, Nanjing 210014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Chu","sequence":"additional","affiliation":[{"name":"Co-Innovation Center for Sustainable Forestry in Southern China, College of Forestry and Grassland, Nanjing Forestry University, Nanjing 210037, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9077-0217","authenticated-orcid":false,"given":"Guanglong","family":"Zhu","sequence":"additional","affiliation":[{"name":"Joint International Research Laboratory of Agriculture and Agri-Product Safety, The Ministry of Education of China, Yangzhou University, Yangzhou 225009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lihua","family":"Ning","sequence":"additional","affiliation":[{"name":"Co-Innovation Center for Sustainable Forestry in Southern China, College of Forestry and Grassland, Nanjing Forestry University, Nanjing 210037, China"},{"name":"Maize Research Centre, Jiangsu Academy of Agricultural Sciences, Nanjing 210014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Javed, T., Indu, I., Singhal, R.K., Shabbir Rubab Shah, A.N., Kumar, P., Jinger, D., Dharmappa, P.M., Shad, M.A., Saha, D., and Anuragi, H.
