Rekha Attanayake

Rekha Attanayake

PhD Candidate

School of Engineering, Information Technology and Physical Sciences

Supervisors: Assoc Prof Peter Dahlhaus and Dr Nathan Robinson

Rekha commenced her PhD with CeRDI in 2019 with Southern Farming Systems, Victorian Limestone Producers Association and Precision Agriculture as industry partners. Her research will explore and develop novel approaches to advance understanding of lime type, quality, variability and spreadability on performance for agricultural purposes under current farming systems and practices.


Developing a reliable, accurate and practical methodology to compare different lime types to better reflect their quality and reactiveness in soils
Developing new methods to help farmers make decisions on lime use and lime requirement

Soil acidity is recognised as one of the major soil constrains to increased agricultural productivity in Australia.
