Summary
This study applied dual-scale micro-computed tomography to characterise soil structural responses to long-term fertilisation treatments. By imaging soil samples across complementary spatial resolutions, the authors quantified changes in pore geometry and aggregate architecture, bridging the gap between microscale pore networks and macroscale soil function. The work contributes to understanding how fertilisation regimes alter physical soil structure and potentially affect water retention, aeration, and root penetration.
Regional applicability
The study's geography is not specified in the metadata; transferability to United Kingdom soils depends on soil type, climate, and cropping system similarity. If conducted in temperate Europe (suggested by author affiliations and journal scope), findings may be broadly applicable to UK arable soils, though local validation would be warranted given variation in soil parent material and management intensity.
Key measures
Soil pore structure parameters (porosity, pore size distribution, pore connectivity), aggregate size and shape, quantified via micro-CT scanning at two spatial scales
Outcomes reported
The study used dual-scale micro-computed tomography to quantify changes in soil pore structure and aggregate morphology across multiple fertilisation treatments in a long-term field experiment. The assessment likely compared structural characteristics (porosity, pore size distribution, connectivity) between fertilised and control soil samples.
