Understanding plant residue decomposition by linking organic matter chemistry and soil microbiology. Soils are an important source or sink for CO2. Currently we lack a fundamental understanding of plant residue decomposition and their transformation into various soil organic carbon (SOC) pools. Since these different pools of soil C are recycled back to atmosphere at different rates, a better understanding of the process is crucial for our ability to manage soil C and to predict the impact of man ....Understanding plant residue decomposition by linking organic matter chemistry and soil microbiology. Soils are an important source or sink for CO2. Currently we lack a fundamental understanding of plant residue decomposition and their transformation into various soil organic carbon (SOC) pools. Since these different pools of soil C are recycled back to atmosphere at different rates, a better understanding of the process is crucial for our ability to manage soil C and to predict the impact of management on SOC. For the first time we will combine detailed chemical analyses of soil organic matter fractions with determination of decomposition rates and microbial community structure; thereby also increasing the knowledge of how Australia's biodiversity is modulated.

Summary
High resolution airborne radar for environmental research: soil moisture, vegetation, salinity and terrain mapping. There is a rapidly increasing demand for a range of environmental data. For example, information on soil moisture status is required for efficient and sustainable water use. Moreover, irrigation practices and large scale clearing have led to serious land degradation through increased salinity from rising water tables. Combined soil moisture and salinity measurement will provide im ....High resolution airborne radar for environmental research: soil moisture, vegetation, salinity and terrain mapping. There is a rapidly increasing demand for a range of environmental data. For example, information on soil moisture status is required for efficient and sustainable water use. Moreover, irrigation practices and large scale clearing have led to serious land degradation through increased salinity from rising water tables. Combined soil moisture and salinity measurement will provide important insight to this complex issue. Further, understanding the complex and rich biodiversity of Australian flora and its adaptation to droughts and fire is essential to ensuring Australian ecosystem longevity. Knowledge of flora changes through time as a function of soil moisture content and salinity is key to gaining this understanding.Read moreRead less
