Abstract: Near-infrared reflectance spectroscopy (NIRS) has been accepted as a fast method to evaluate various soilconstituents. However, very few studies have used NIRS as a predictor of the textural and mineralogicalcontent of tropical soils. The objective of this study was to investigate the potential use of NIRS as a toolfor assessment of diverse soil properties, with specific attention to the prediction of properties related tothe mineralogy of a wide range of Latosols from the Cerrado region of central Brazil. The reflectance ofthe soil samples, 148 in total, taken from 0.0 to 0.2 and 0.6 to 0.8-m depth, was determined in the near-infrared region between 1100 and 2500 nm at 2-nm intervals with a NIRS spectrophotometer. Our resultsshow that for soil sampling corresponding to a large-scale map and taking into account the variability ofLatosols over a wide region, NIRS can predict most of the mineralogical properties of the Latosols accurately.Near-infrared spectroscopy did not predict most of the physico-chemical characteristics of soils accurately,in particular those that are largely dependent on agricultural practice, such as pH or CEC. However, themain characteristics that correspond to soil constituents (organic matter and clay content) were relatively wellpredicted. |
