Soil organic matter (OM) plays a critical role in ecosystem services provided by soils. This is not only because soil OM determines soil health and maintains fertility to support ecosystem productivity, but also soil OM can be managed as a potential C sink for atmospheric CO2 via C sequestration. Soils store the largest organic carbon (C) stock with around 700 Pg of C in the top 30 cm of soil or around 1500 Pg of C to a depth of 1 m, which is about three times of C in plant and animal biomass combined. However, not all soil organic C are stable, some of them can be particularly labile and lost back to the atmosphere. Thus, there is an increasing interest in a more detailed understanding of the mechanisms controlling both the turnover and stabilisation of soil organic C. It has been suggested that organic C bound by clay minerals (i.e. metal oxides, oxyhydroxides, and hydroxides) are key processes to the stabilisation of soil organic C. Therefore, the overall aim of this proposed study is to investigate the soil organic C stabilisation potential of kaolinite and related iron (Fe) oxides that are bi-products of kaolinite mining. A good understanding of the stabilization mechanisms in Western Australian soils will help adopt management practices to sequester C, improving soil structure, water holding capacity and mitigate of greenhouse gas emissions.
