- ... Partial least squares regression (PLSR) analysis was used for the generic prediction of soil organic C (C) content in Alfisols using diffuse reflectance Fourier-transform mid-infrared spectroscopy (DRIFT-MIRS). For prediction improvement, we tested the potential of C removal by heating and spectral subtraction of mineralogic signals in DRIFT-MIRS spectra. Eighty-seven Alfisol samples (C range 1–32 ...
