Journal ArticleDOI
Linking air and water transport in intact soils to macropore characteristics inferred from X-ray computed tomography
Sheela Katuwal,Trine Norgaard,Per Moldrup,Mathieu Lamandé,Dorthe Wildenschild,Lis Wollesen de Jonge +5 more
TL;DR: In this article, the authors used X-ray computed tomography (CT) scans to evaluate gas transport behavior in macropore networks under these conditions and found that CT-derived macroporosity and air-filled porosity for the limiting-quarter section of each column were highly correlated with both k a20 and T 5% (R 2 from 0.6 to 0.8).
Journal ArticleDOI
X-ray CT-Derived Soil Characteristics Explain Varying Air, Water, and Solute Transport Properties across a Loamy Field
Marcos Paradelo,Marcos Paradelo,Sheela Katuwal,Per Moldrup,Trine Norgaard,Lasantha Herath,Lis Wollesen de Jonge +6 more
TL;DR: In this article, X-ray computed tomography (CT) can be applied for this characterization, and in this study CT-derived parameters were used to explain water, air, and solute transport through soil.
Journal ArticleDOI
Effects of CT Number Derived Matrix Density on Preferential Flow and Transport in a Macroporous Agricultural Soil
TL;DR: In this paper, a combination of standard physical measurement methods for air and water permeabilities, breakthrough experiments, and X-ray computed tomography (CT) on large soil columns was used to establish links between the structural pore space and preferential transport.
Journal ArticleDOI
Characterising and linking X-ray CT derived macroporosity parameters to infiltration in soils with contrasting structures
Karin Müller,Sheela Katuwal,Iain M. Young,Malcolm Mcleod,Per Moldrup,Lis Wollesende de Jonge,Brent Clothier +6 more
TL;DR: In this paper, the authors used X-ray computed tomography (CT) to estimate hydraulic properties of macropore hydraulic properties in three horizons of an Andosol and a Gleysol.
Journal ArticleDOI
Effect of Root Density on Erosion and Erodibility of a Loamy Soil Under Simulated Rain
TL;DR: In this article, the authors evaluated the contribution of roots in soil erosion control and the effect of root density in soil erodibility and soil physical properties, and found a positive correlation between soil shear strength and root density, but no influence of roots on bulk density and saturated hydraulic conductivity.
