Magnetic susceptibility (χ, mass specific) is useful for easy indirect estimation of other soil properties at a low cost. The aim of this study was to assess the use of χ as measured with an analytical balance for predicting properties with a substantial influence on the management of Typic Haplustalfs in southern Brazil. To achieve this 48 topsoil samples were taken at the intersection points in a rectangular grid of 20 m × 20 m cells, with 38 of these used for calibration and 10 for validation in ...
