Research expertise

  • Greenhouse gas emissions
  • Acid soil management
  • Grazing management
  • Crop and pasture agronomy


Dr Guangdi Li obtained his Bachelor and Master degrees at Gansu Agricultural University, China, and his PhD at Massey University, New Zealand. Dr Guangdi Li joined the NSW Department of Primary Industries since 1997. He has extensive research experience in Australia, China and New Zealand.  He has established and led large research teams across organisations working on national and international issues, such as soil acidity, climate change, greenhouse gas emissions and soil organic carbon sequestration, adding major value to public goods and making significant contributions to the scientific literature and communities. His research work published widely in scientific journals, conferences and organisation websites across a wide range of research areas in pasture agronomy, crop and pasture management, pasture species evaluation, acid soil management, nitrous oxide emissions.
