Overview

My research focusses on soil health in cropping and pasture systems, specialising in soil carbon and soil organic matter dynamics, microbial ecology, and plant-soil interactions. I am interested in how agronomic interventions impact soil health and in developing methods to reverse soil fertility decline and build healthier, more productive soils. This includes understanding the impacts of tillage, cover cropping, crop rotational diversity, nutrient management, and organic amendments on soil functional processes and crop development and productivity.

I have extensive experience in designing and analyzing field and glasshouse experiments and implementing advanced statistical models using R. I have excellent verbal and written communication skills, maintain positive relationships with collaborators both nationally and internationally, and publish manuscripts in peer-reviewed scientific journals.

Available Projects

  • A PhD project is available with The University of Queensland and the Northern Australia Crop Research Alliance (NACRA) as part of the CRC for Developing Northern Australia. The PhD would spend significant time in Kununurra, WA, working with NACRA, WA DPIRD, and local growers to conduct cropping systems research. Potential avenues of PhD research include improving nitrogen management, investigating the feasibility of cover cropping, and exploring cropping system effects on soil health. Major crops in the systems include cotton, maize, and grain legumes. The student will need to successfully obtain a UQ Graduate School Scholarship, and a stipend top-up will also be provided through the project grant. Potential applicants will require either an Honours or Masters level qualification with competitive GPA to attract a UQ Scholarship. Please contact Alwyn Williams (alwyn.williams@uq.edu.au) for more information.

  • Soil health in Australian cropping systems is declining, undermining long-term production potential. Ongoing research opportunities are available to investigate soil health-related issues, ranging from soil fertility and soil organic matter turnover dynamics, soil carbon, novel cropping practices (including methods of ecological intensification, e.g., cover cropping, intercropping, and increasing crop rotational diversity), soil-crop nutrient management (including impacts of contrasting fertiliser strategies as well as use of organic amendments), and analysis of soil biota and plant-soil interactions. Students with a strong GPA are welcome to contact Alwyn to discuss project opportunities.
