  abstract = {{T}he description of soil structure is primordial to determine the effects of management practices on soil environment. {D}ifferent techniques were developed to determine the pore structure, each with its own limitations. {I}n this study mercury intrusion porosimetry ({MIP}) and {X}-ray microtomography (micro-{CT}) were used to study the total porosity and pore size distribution of soil aggregates (5-6 mm) treated with different fertilisations (organic, mixed and mineral). {T}he network model {P}ore-{C}on was applied to pore distribution curves to highlight subtle structural properties affecting the aggregates. {T}he combination of these techniques highlighted that: (1) {MIP} was fundamental to reveal the small pores that were not detected by micro-{CT} and that represented up to 70% of total porosity; (2) micropores (30-6.25 mu m) detected by {MIP} were underestimated with respect to micro-{CT} (-9.4%) probably due to the "ink bottle" effect, whereas meso- and macropores were overestimated; (3) only micro-{CT} highlighted the effects of organic amendants on pore morphology. {T}hese outcomes were compared with modelling results of the network model {P}ore-{C}or that proved its ability to predict the pore structure organisation and the differences between fertilisations. {F}urther improvement of micro-{CT} will allow to cover a wider range of pores, but at present the integration with different techniques is still fundamental.},
