Dr. Zhifeng Xun | Soil Carbon | Best Researcher Award

Lecturer | Liaoning Agricultural Vocation and Technical College | China

Dr. Zhifeng Xun is a lecturer at Liaoning Agricultural Vocational and Technical College with a strong academic background in Grassland Science and Turfgrass Resources and Utilization. His research focuses on soil carbon and nitrogen cycling and the microbial pathways responsible for the production of the greenhouse gas nitrous oxide (N₂O). Through a combination of biological inhibition experiments and high-throughput sequencing, he has identified fungi, particularly Ascomycota, as significant contributors to N₂O emissions under nitrogen fertilization, revealing that moderate nitrogen input disproportionately stimulates fungal-driven emissions. Dr. Zhifeng Xunhas contributed to multiple major research programs, enhancing the understanding of microbial mechanisms in urban lawn soils and providing a scientific foundation for sustainable nitrogen management in green spaces. He has authored four journal publications and a book, advancing knowledge in ecosystem management and climate change mitigation. His work integrates soil science and microbial ecology to inform practical strategies for reducing greenhouse gas emissions and promoting resilient, sustainable urban landscapes. His research has garnered 16 citations across 16 documents, with an h-index of 2.
