Resumo: | The aim of this study was to evaluated the facility to apply spectroscopic analysis coupled with chemometrics analysis as a rapid method for soil analysis. Soil samples from different depths (0-10, 10-20 and 20-30 cm) and treatment sites (area of fallow land for 5 years, area of no-tillage for 10 years and native forest) were applied in this study. Soil chemical characterization based on the concentration of macro-, micronutrients and the level of the toxic element showed significant different among to the samples under differences management systems. PCA and HCA analysis evaluated with soil chemical characterization showed that the samples were grouped according to the management systems. Similar results were obtained in the PCA and HCA analysis developed with FTIR spectra. The results support the application of FTIR to evaluate the quality of soil providing a simple, rapid, and nondestructive method for the soil science.
