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...

Improving the auditability of soil carbon

Soil systems are recognised as a significant terrestrial sink of carbon. The reliable assessment and monitoring of soil carbon stocks is of key importance for soil conservation and more...

Plant-microbial interactive effects on soil carbon in relation to soil structure

Maintaining healthy soils is vital for sustaining terrestrial life on earth.  The functioning of soil is to a large degree defined by its structure.  Soil structure affect 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...

Maximising the benefits of biochar addition to soil by understanding mineral–biochar interactions

Biomass-derived natural biochar, also referred to as black carbon, is ubiquitous in soils. Soil biochar can influence a number of biogeochemical processes, and serves as a sink for more...

Trees during the Last Glacial Maximum: just cold or cold and starving?

During the cold glacials, global levels of atmospheric CO2 were as much as 30% lower than those of the recent pre-industrial past. Forests in the southern hemisphere were much more more...

Mesophyll conductance and water-use efficiency of grain crops

Efficient use of water is the most pressing environmental issue facing the Australian grain industry.  While significant research effort has been employed to improve water-use more...

Charcoal production during prescribed fire and its role in carbon turnover

Prescribed fires convert variable amounts of biomass into a variety of forms of ‘black carbon’.  Both the rate (and efficiency) of conversion and the forms of black 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...

Can planting trees make it rain? Investigations into land surface atmosphere feedbacks

Over the last couple of years there has been significant discussion about the coupling of the earth surface with the atmosphere and in particular the feedback between soil moisture more...
