Eligible to supervise Masters and PhD - email supervisor to discuss availability.
Ashlea is a post doctoral researcher and lecturer in Soil Science in the School of Agriculture, Food and Wine. Her research and teaching interests are in soil chemistry and how nutrients are stored, transformed and cycled in soils.
Ashlea's research primarily focuses on soil phosphorus chemistry and she has a particular interest in:
• The characterisation and quantification of different forms of organic phosphorus and their availability to plants.
• The the influence of crop rotations and agronomic strategies to improve phosphorus availability in soil.
• 31P NMR analysis and the development of NMR techniques for the analysis of soils and plants.
