WebAll FTIR spectra were acquired in ATR mode with an FTIR Bruker Alpha Platinum spectrometer (Bruker ©, Billerica, MA, USA) coupled to OPUS software (Bruker ©, Billerica, MA, USA). Spectra were obtained in the mid-infrared range (4000–600 cm −1) with a resolution of 8 cm −1 and 64 co-added scans. Spectral acquisition was performed in a ... WebSoil FTIR-ATR spectra were integrated with remote sensing data to offer a framework for SOM mapping. This framework included optimization of calibration size, prediction of SOM content for sampled sites based on the fusion of FTIR-ATR spectra, Sentinel-2 bands, indices, and DEM derivates, and generation of a SOM map by machine learning.
