Resumen

This study aimed to investigate the potential use of magnetic susceptibility (MS) as a property to characterize the soil state in two lots under cultivation of sugar cane. The MS is a property that determines the degree of magnetization of a material, and it has a potential use in the diagnosis of agricultural soils due to its measurement versatility. Soil samples were collected, and subjected to laboratory analysis from two lots named Chondular (55.3 ha) and Santa Rosa (98.3 ha),in order to measure the MS and compare it with the conventional physic properties. Data were submitted to descriptivestatistics by calculating the mean and the coefficient of variation. In order to investigate the relation of the MS with other soil physical properties it was made a correlation matrix. The results shown that MS, in both sugarcane lots, has statistical correlation with physical soil properties. For lot Chondular, it was noticed a similar behavior of relationship between MS, and the content of clay and sand. The lot Santa Rosa shows high, and direct relation with other properties such as field
capacity, bulk density, and total pore space. The use of MS parameter in soil diagnostic allows inferring with high assertiveness the general physical condition of agricultural soils located in the flat area of Valle del Cauca, Colombia, reducing significantly processing times, environmental impact (due to the chemical reagents used), and costs in conventional laboratory tests.
