Examining the potential for climate change mitigation from zero tillage (2015)
Journal Article

The benefits of reduced and zero-tillage systems have been presented as reducing runoff, enhancing water retention and preventing soil erosion. There is also general agreement that the practice can conserve and enhance soil organic carbon (C) levels... Read More about Examining the potential for climate change mitigation from zero tillage.

Three-dimensional quantification of soil hydraulic properties using X-ray Computed Tomography and image-based modeling (2015)
Journal Article

We demonstrate the application of a high-resolution X-ray Computed Tomography (CT) method to quantify water distribution in soil pores under successive reductive drying. We focus on the wet end of the water release characteristic (WRC) (0 to ?75 kPa)...

Using X-ray computed tomography to explore the role of abscisic acid in moderating the impact of soil compaction on root system architecture (2015)
Journal Article

Assessing the effect of fibre extraction processes on the strength of flax fibre reinforcement (2014)
Journal Article

A number of factors impede the direct translation of fibre properties from plant crop species to natural fibre composites. Commercially available fibre extraction processes introduce defects and degrade the mechanical properties of fibres. This study...

On the evaluation of methods for the recovery of plant root systems from X-ray computed tomography images (2014)
Journal Article

© CSIRO 2015. X-ray microcomputed tomography (μCT) allows nondestructive visualisation of plant root systems within their soil environment and thus offers an alternative to the commonly used destructive methodologies for the examination of plant root...

Branching out in roots: uncovering form, function, and regulation (2014)
Journal Article

Root branching is critical for plants to secure anchorage and ensure the supply of water, minerals, and nutrients. To date, research on root branching has focused on lateral root development in young seedlings. However, many other programs of postemb...

Plant roots use a patterning mechanism to position lateral root branches toward available water (2014)
Journal Article

The architecture of the branched root system of plants is a major determinant of vigor. Water availability is known to impact root physiology and growth; however, the spatial scale at which this stimulus influences root architecture is poorly underst...

To what extent can zero tillage lead to a reduction in greenhouse gas emissions from temperate soils? (2014)
Journal Article

Soil tillage practices have a profound influence on the physical properties of soil and the greenhouse gas (GHG) balance. However there have been very few integrated studies on the emission of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2...

Quantification of changes in zero valent iron morphology using X-ray computed tomography (2013)
Journal Article

Morphological changes within the porous architecture of laboratory scale zero valent iron (ZVI) permeable reactive barriers (PRBs), after exposure to different groundwater conditions, have been quantified experimentally for different ZVI/sand ratios...

Impact of flavour solvent on biscuit micro-structure as measured by X-ray micro-computed tomography and the distribution of vanillin and HMF (HPLC) (2012)
Journal Article

The influence of flavour solvent, propylene glycol (PG) and triacetin (TA), was investigated on the micro-structure (as measured by X-ray micro-Computed Tomography, X-ray ?CT) and aroma compound distribution (as measured by HPLC) within shortcake bis...

Quantification of pore clogging characteristics in potential permeable reactive barrier (PRB) substrates using image analysis (2006)
Journal Article

Permeable reactive barriers (PRBs) are now an established approach for groundwater remediation. However, one concern is the deterioration of barrier material performance due to pore clogging. This study sought to quantify the effect of pore clogging...

Quantification of the effects of pore clogging in potential PRB substrates using image analysis (2005)
Journal Article

Permeable reactive barriers (PRBs) have demonstrated a promising approach for groundwater remediation. However, one concern is the deterioration of barrier material performance due to mineral precipitation and pore clogging. This study sought to quan...

Suitability testing of selected wastes and natural substrates for permeable reactive barriers (PRBs) (2005)
Journal Article

Performance of barrier materials is important for the long-term success of permeable reactive barriers (PRBs). A number of selected wastes and natural materials were tested in batch experiments for their ability to remove heavy metals from synthetic...

Natural and waste materials as metal sorbents in permeable reactive barriers (PRBs) (2005)
Journal Article

A range of waste products and natural materials including chitin, fly ash, clay soil, cocoa shell, calcified seaweed and the natural zeolite clinoptilolite were tested in batch experiments to assess their ability to remove metals from a synthetic gro...
