Mineral-organic interactions in soil aggregation and protection of soil organic carbon

Soil organic matter (SOM) represents the largest terrestrial carbon pool. The mineralisation of SOM has a major impact on the global carbon cycle and therefore research is needed to more...

How does carbon affect soil structure?

Soil structure plays an important role in maintaining the quality of soil, mediating important biological, chemical and physical soil processes. Soil structure determines water rete more...

Soil Organic Carbon amount and turnover time in perturbated soil systems using radioactive carbon signature

The project is aimed at modeling the stock and turover time of carbon-based soil organic matter using 12C and 14C observations in non-stationary systems. The modeling foresees the u more...

Earthworms and soil physical quality

Earthworms are called soil ecosystem engineers, as they affect the soil physical properties such as soil structure through their feeding, burrowing and casting activities. While the more...

Black Carbon in Soils

Carbon emissions during bushfires may be very large for southern forests in Australia. This may be offset in part by the deposition of black carbon or charcoal to the soil surface. more...

Uncovering the source of CO2 that’s respired when dry soil is rewet

Soil respiration is one of the largest components of the global C cycle, but also one of the hardest to model. A key aspect of this difficulty is that we do not have a good mechanis more...

Aeolian dust in contemporary Australia – a fertiliser, a contaminator or just an occasionally spectacular nuisance?

Aeolian dust usually receives little popular attention in Australia until a massive, rolling dust storm blows out of the arid interior and reduces visibility and air quality across more...

Do co-occurring plants avoid competing for N?

All plants require nitrogen, so how can species co-exist if they're competing for the same limiting resource? This project will examine the hypothesis that plants avoid competing fo more...
