• Subjects: calcium carbonate; clay; electrical conductivity; fluorescence; gypsum; infrared spectroscopy; Iran; least squares; Mid-IR and pXRF spectroscopy; PLSR, arid region; prediction; salinity; sand; silt; soil organic carbon; soil salinity; Soil spectral behavior; soil texture; Vis-NIR-SWIR; X-radiation; Iran; Vis-NIR-SWIR; Soil spectral behavior; Mid-IR and pXRF spectroscopy; PLSR, arid region

The aim of the current research was to examine the effectiveness of Vis-NIR-SWIR (visible, near-infrared, and shortwave infrared spectroscopy: 350–2500 nm), MIR (mid-infrared spectroscopy: 4000–400 cm−1), and pXRF (portable x-ray fluorescence) to characterize and estimate clay, sand, silt, calcium c...
