    ABSTRACT A multispectral technology as tool for assessing the susceptibility to erosion and desertification in humid zones from the European Mediterranean was applied by means of the use of spectral reflectance data to determine the contents of different attributes of the soils. A collection of field electromagnetic spectrums were obtained from 25 covers of soil, a derivative analysis was applied to electromagnetic spectrums and finally a PCA was made. The results showed good correlations (R2>0,5) between properties of soil and electromagnetic spectrums, therefore it is possible to determine the content of these soil attributes with spectral analysis, which minimizes cost and time.
