Ahead of the NSW state election on 25 March 2023, the NSW Government caretaker period has commenced. Limited updates will be made to this website during this period.

Shihab Uddin

Research Scientist

Research interests

  • Understanding the mechanism of subsoil amelioration with different amendments
  • Soil management for improving crop productivity
  • Improving crop water use efficiency in constrained soils
  • Plant water relations in a changing climate
  • Crop responses under changing climate e.g. high CO2, drought


Dr Shihab Uddins current work is focussed on minimising the yield gap in alkaline dispersive soils by selecting novel genotypes and/or subsoil application of amendments. Dr Uddin is using organic and inorganic amendments and their combination with unique chemical properties in order to understand the structural transformations of alkaline dispersive soils and the associated crop responses such as root growth and water use efficiency.

Dr Uddin’s PhD research was focussed on the interdependence between elevated CO2-induced stimulation of plant biomass especially leaf area and leaf-level water use efficiency on water use of dryland crops. In addition, root growth and subsoil water extraction dynamics under elevated CO2 were major part of his PhD research.
