Identification of minerals in subtropical soils with different textural classes by VIS–NIR–SWIR reflectance spectroscopy

Popis výsledku v původním jazyce

The physical and chemical attributes of soils are strongly influenced by the nature of the minerals they contain and their concentration. Thus, soil texture is directly dependent on the content in clayey minerals, which influences a number of characteristics such as water dynamics. Although the mineralogical composition of soil is usually determined by X ray diffraction spectroscopy, this technique is expensive and time-consuming, and uses toxic materials, all of which makes it impractical for obtaining large data sets. Also, available methods for acquiring, interpreting and examining visible near infrared shortwave infrared VIS NIR SWIR spectra are largely ineffective with tropical soils. The aim of this work was to ascertain whether VIS NIR SWIR reflectance spectroscopy is useful for identifying minerals in subtropical soils as classified by textural class. For this purpose, soil samples were collected at 66 points at three different soil depths over a study area located in the State of Rio Grande
