International audience. 1- Visualisation of short-time (< 10 min) soil structure dynamics at the µm scale during the rewetting period (1s fast-scanning)2- Observation of microcrack formation during drying and wetting events3 – Soil structure deformation is affected by agricultural practices: more intense deformation under conventional agriculture compared to conservation agriculture4- Soil structure deformation seems more intense in larger size aggregates (6-8 mm) than in the smaller ones (2-3 mm) 5- Visualisation of organic matter stained by osmium
