Modifications structurales (assemblage élémentaire) liées à l'activité racinaire au sein de sols limono-argileux
Abstract
The groundmass porosity was studied in scanning electron microscopy by using the back-scattered electrons. The image analysis showed the groundmass fabric as altered around pores owing to root activity. This alteration of the groundmass fabric concerns the lacunar porosity which was decreased by a third around the studied pores. The results showed that the latter differentiated themselves within a groundmass fabric more porous than the one currently surrounding them
