Characterisation of the structural heterogeneity of the soil layer by using in situ 2D and 3D electrical resistivity measurements

Introduction Soil structure i. e. the arrangement of soil particles in space (Guérif, 1987) is one important factor of physic quality of soils. In the agricultural context, this structure is modified at several space and time scales by different constraints or processes: tillage, compaction by traffic, natural effects. We need methods to characterize its in situ state. They already exist but they are destructive and time consuming. Recent works (Besson et al., 2004) have shown that a compacte..
