Li Guangdi


Dr Guangdi Li obtained his Bachelor (1982) and Master degrees (1985) at Gansu Agricultural University, China and did his PhD at Massey University, New Zealand, focused on response of chicory (Cichorium intybus L.) to defoliation during 1993-1997. Dr Guangdi Li joined the NSW Department of Primary Industries since 1997. He has extensive research experience in Australia, China and New Zealand.  Over the last 10 years, he published more than 70 refereed journal papers across a wide range of research areas in pasture agronomy, crop and pasture management, pasture species evaluation, soil chemistry and physics, and acid soil management. Currently, he is leading a multi-disciplinary research team across 4 research organizations in partnership with 4 leading growers groups, focusing on innovative approaches to managing subsoil acidity in the southern grain region in Australia.
