Magnetic susceptibility (MS) is a property that determines the degree of magnetization of a material according to its composition; therefore, it has potential in the assessment of agricultural soils. This study aimed to the application of this attribute to the physical analysis of soils, by determining its correlation with some physical properties in soils of Valle del Cauca. Samples were taken in two lots of sugar cane (Chondular and Santa Rosa), of 55 and 98 hectares, respectively. The lots were analyzed by descriptive statistics and spatial and Pearson correlation between MS and the physical properties of the soil, through a geographic information system software. High spatial correlations were found between MS and the properties analyzed, particularly sand and clay content (0.9 and -0.88, respectively, P
