Professor David Chittleborough

Doctor David Chittleborough received his PhD in Pedology in 1982 at the University of Adelaide on the development of soil chronosequences in eastern Australia. At the time he was a field pedologist mapping soils in central South Australia. He joined the Department of Soil Science of the University of Adelaide in 1983 at which time he began research on processes of non-point source pollution, specifically the impact of soil processes and soil management on water quality. He has developed methods to reduce the impact of phosphorus and dissolved organic carbon in runoff from catchments by the addition of chemical amendments to soils. David is also engaged in studying the origin and properties of soils with subsurface physical and chemical constraints using high resolution x ray scanning tomography to image pores and roots in intact soils. A recent extension of this work involves the study of the chemistry of the rhizosphere using synchrotron-based x ray absorption techniques. David has an interest in developing new techniques to separate and analyse the finest particles in soils - the soil colloids. He is a member of the recently-formed Hydropedology Working Group of the International Union of Soil Science and is on the Organising Committee for it's second International Conference to be held in Leipzig, Germany in 2012 (http://www.ufz.de/hydropedology2012/hydropedology/Scientific_Board.html). He was co-founder and director of the University's Water Research Cluster and is now on the Executive and Advisory Board of the newly-formed Water Research Centre http://water.adelaide.edu.au/, where he leads the Hydropedology Program. He also has a long-standing interest in natural resource science and management and is a member of the Environment Institute's Landscape Futures Program where he is working on setting up observatories to monitor ecosystem and hydropedological processes.
Teaching InterestsDavid is a member of two Disciplines in the School of Earth & Environmental Sciences viz. Geology & Geophysics and Soil & Land Systems. He teaches Pedology, which is the study of the origin, development, properties and distribution of soils, in two courses of the Environmental Geoscience major viz. Landscape Processes and Environments II and Environmental Geoscience Processes III
He also teaches parts of courses in the Bachelor of Science (Agricultural Science) and Bachelor of Science (Natural Resources)viz. Earths Environment I, Integrated Catchment Management III and Soil Water Management III
To do these courses enrol in the flagship course in the Faculty of Sciences â€“ http://www.adelaide.edu./au/programs/ and select Science
Overall Dr Chittleborough is interested in the origin, properties and distribution of soils and their management, particularly Australian soils and their properties, such as texture contrast and sodicity, which are manifest in such a wide variety of forms and which pose such a challenge for human habitation.
David is a member of the Soil Chemistry Group and a recently-formed Hydropedology Group
Specific areas of research interest
2. Colloid separation technology Methods such as Flow Field-flow Fractionation for isolating colloids and nano particles from soils and sediments.
3. Environmental nanoparticles Origin, physical, mineralogical and chemical properties, and transport through soils and catchments.
4. Physico-chemistry of root-soil interactions. Development of non destructive means of characterising the architecture of the soil pores using x ray computed tomography and studying the chemistry and mineralogy of the soil-pore interface using techniques such as X-ray Absorption spectroscopy, micro-X ray fluorescence spectrometry and surface analytical techniques such as X-ray photon spectroscopy.
5. Salinity and sodicity and the origin and development of saline soils an repair of damaged landscapes.
