Soils with stagnic properties occurring in Alentejo commonly have low porosity. The study of a typical soil toposequence, showed that soil pore features were significantly different amongst summit and foot/toe slope pedons. In the summit pedon the Ap1 horizon was more porous than the Ap2, both exhibiting similar void distribution patterns. Conversely, the Ap1 and Ap2 horizons of the footslope pedon had a simila...
