Background

Dr Guangdi Li joined the NSW Department of Primary Industries in 1997. He has extensive research experience in Australia, China and New Zealand.  Over the last 10 years, he published more than 40 refereed journal papers across a wide range of research areas in acid soil management, pasture and crop agronomy, pasture species evaluation, grazing management, animal production, tillage management and soil conservation. He is leading and involved in a number of research projects, including international collaborative projects.

• BAgrSc  – Gansu Agricultural University, China, 1982
• MAgrSc – Gansu Agricultural University, China, 1985
• PhD in Plant Science – Massey University, New Zealand, 1997

Current projects

• Facilitating increased on-farm adoption of broadleaf species in crop sequences to improve grain production and profitability (GRDC 2010-2015)
• Developing the role for perennials in mixed-farming systems - Uniform rainfall region (FFI CRC 2008-2014)
• Improved perennial grass cultivars for the inland slopes of the Great Dividing Range (FFI CRC 2008-2014)
