Abstract

Employing x-ray computed tomography (μ-CT), we examined the impact of an oil mallee (OM) biochar, at concentrations of 0%, 1% and 5% (w/w), on soil structural traits in three soil types (Vertisol, Ferralsol and Arenosol). The biochar was pyrolysed at a maximum temperature of 550°C, sieved to between 250μm and 2mm prior to amending the soils, had an internal porosity of 75% (v/v) and an organic carbon (Corg) content of 60%. Soil structure was quantified, at a resolution of 70μm, by measuring μ-CT porosity, mean pore radius, fractal dimension and connectivity of the pore space. Addition of 5% OM biochar resulted in higher μ-CT porosity (i.e. ≥70μm) in the Vertisol (p
