Quantification of root water uptake in soil using X-ray computed tomography and image-based modelling: Quantification of root water uptake in soil (2017)
Journal Article

Spatially averaged models of root-soil interactions are often used to calculate plant water uptake. Using a combination of X-ray Computed Tomography (CT) and image based modelling we tested the accuracy of this spatial averaging by directly calculati...

The holistic rhizosphere: integrating zones, processes, and semantics in the soil influenced by roots (2016)
Journal Article

Despite often being conceptualized as a thin layer of soil around roots, the rhizosphere is actually a dynamic system of interacting processes. Hiltner originally defined the rhizosphere as the soil influenced by plant roots. However, soil physicists...

Visual tracking for the recovery of multiple interacting plant root systems from X-ray ?CT images (2015)
Journal Article

We propose a visual object tracking framework for the extraction of multiple interacting plant root systems from three-dimensional X-ray micro computed tomography images of plants grown in soil. Our method is based on a level set framework guided by... Read More about Visual tracking for the recovery of multiple interacting plant root systems from X-ray ?CT images.

Extracting multiple interacting root systems using X-ray microcomputed tomography (2015)
Journal Article

© 2015 The Authors The Plant Journal published by Society for Experimental Biology and John Wiley & Sons Ltd. Root system interactions and competition for resources are active areas of research that contribute to our understanding of how roots perc...

Impacts of zero tillage on soil enzyme activities, microbial characteristics and organic matter functional chemistry in temperate soils (2015)
Journal Article

Zero tillage management of agricultural soils has potential for enhancing soil carbon (C) storage and reducing greenhouse gas emissions. However, the mechanisms which control carbon (C) sequestration in soil in response to zero tillage are not well u...

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

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...

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...
