AbstractThe topography is one of the main physical factors that can affect the spatial variability of the magnetic minerals in soils. The magnetic susceptibility is related with the concentration of the magnetic minerals therefore linked to the degree of soil degradation and soil conservation status. In this contribution, four topographic factors have been analysed and related to values of magnetic susceptibility in order to infer the effect of the topographic factors on the spatial variability of the magnetic minerals in soils. The study area is a cultivated field in the Spanish Prepirinean border. The geomorphometric landscape analysis permits to assess and assign the value of a given topographic factor in each pixel of the digital elevation model in the study field. The results show the direct and statistically significant relationship between the spatial distribution of the concentration of the magnetic minerals in cultivated soils and the topographic factors such as elevation and slope that affect the processes of soil redistribution.
