Genesis and properties of representative Ferralsols from the Brazilian Cerrado of Piauí

Abstract Ferralsols cover substantial areas in tropical regions, yet their pedogenesis on sedimentary rocks remains insufficiently understood. This study aimed to characterize the morphological, physical, chemical, and mineralogical properties of five representative sandy-texture...

Portable X-ray fluorescence spectrometry library for Brazilian soils: chemical characterization and prediction of soil particle size fractions across all biomes

Sensor-based soil data libraries have proven valuable for a wide range of applications. Given the increasing adoption of portable X-ray fluorescence (pXRF) spectroscopy for soil-related studies, we aimed to create a library of soils characterized by pXRF and develop prediction mo...
