dc.descriptionABSTRACT : The absorption of light resulting from electronic and molecular processes, taking place in clay minerals, metal oxides and hydroxides, carbonates, sulfates, organic matter, water et c... determine specific features in soil reflectance spectra that can be used for their identification and, in some cases quantification. These possibilities, makes from spectral reflectance data obtainable in laboratory, in the field, through aircraft or spacecraft plat- forms, a promising tool for identification of mineral components, monitoring of organic matter and soil water contents. The use of reflectance spectral data for soil characterization is more efficient when based on the knowledge of each component effects on the spectrum, and on the way their association promote deviations of the individual characteristics. In this paper we review some of the research works that have contributed to clarify the spectral characteristics of the reflected light from soils in the visible to medium infrared, measured by different techniques The objective of this paper is to call attention on the possibilities offered by the spectra analysis and to show the difficulties, imposed by the complex nature of soils, in generalizing procedures applicable to all soil types.
