An opportunity is available for an outstanding PhD scholar in the area of soil organic carbon monitoring with the School of Molecular and Life Sciences in the Faculty of Science and Engineering at Curtin University. Maintaining or increasing soil organic carbon (C) is critical to tackling climate change. It is also the most important element controlling soil health, which enables soils to be resilient. Soil organic carbon (C) exerts positive effects on soil physical and chemical properties and increases the soil’s capacity to provide ecosystem services (e.g. the provision of food and the regulation of climate). The amount of soil organic C (per unit area of land) depends on the annual inputs of biomass, the type of land management, the soil type and the vulnerability of soil organic C to decomposition. This is why soil organic C is highly variable in space, across landscapes and down the soil profile. Current methods for measuring the variability in soil organic C and for monitoring its change over time are expensive and inefficient. There’s an urgent need to develop cost-efficient methods to assess and monitor changes in soil organic C, for example, for on-farm C accounting. The new methods must be based on a solid understanding of soil C, its composition and the processes that lead to both its accumulation and loss. The aim of this project is to develop a robust, practical and cost-efficient methodology for measuring the organic C stocks (and C composition) in the soil, for quantifying its variation across landscapes and for monitoring its change over time. The successful candidate will gain experience in soil organic carbon sciences, statistical analyses, new soil sensing methods, empirical modelling, multivariate statistics, machine learning, and current methodologies for soil C accounting.
