Post-doctoral Fellowship: Understanding P dynamics and bioavailability in alkaline clay soils aligned to UQ00082
This investment will use the large amount of current data on phosphorous utilisation to develop an interpretative framework that quantifies the key process interactions and how they influence phosphorous use efficiency and crop growth/yield across different environments. Identified gaps in current knowledge will be the subject of targeted experimentation with a focus on deriving algorithms to link environmental variables with crop phosphorous acquisition and grain yields.
