About
Xiaoyuan Yan is a soil scientist whose research sits at the intersection of nitrogen biogeochemistry, greenhouse gas emissions, and soil microbial ecology. Their work has made significant contributions to our understanding of denitrification processes — the microbial conversion of soil nitrogen into gaseous forms — with particular emphasis on disentangling the complex controls governing emissions of nitrous oxide (N₂O), nitric oxide (NO), and dinitrogen (N₂). A hallmark of Yan's research is the application of direct soil-borne N₂ measurement techniques, a methodologically challenging approach that has yielded rare and valuable insights into the N₂O-to-N₂ ratio under varying management conditions. Their 2018 study on straw amendment, now cited 77 times, demonstrated that organic additions can paradoxically increase N₂O emissions even while shifting the denitrification balance. Subsequent work has explored how land use change, soil moisture dynamics, and nitrate loading interact to shape nitrogen gas fluxes. More recently, Yan has expanded into emerging contaminant research, investigating how tire wear particles reshape soil microbial communities and accelerate denitrification — a timely contribution given growing concerns about microplastic pollution. Collectively, their body of work informs sustainable agricultural and environmental management strategies worldwide.
