Soil organic carbon estimation using VNIR–SWIR spectroscopy: The effect of multiple sensors and scanning conditions

Popis výsledku v původním jazyce

Visible near infrared shortwave infrared VNIR SWIR spectroscopy is being increasingly used for soil organic carbon SOC assessment. Common practice consists of scanning soil samples using a single spectrometer. Considerations have rarely been documented of the effects of using multiple instruments and scanning conditions on SOC model calibration that occur when merging soil spectral libraries SSLs, particularly in soils with low SOC concentration and using both field spectroradiometers and laboratory fixed spectrometers. To address this gap, we scanned 143 low SOC content soil samples using three spectrometers ASD FieldSpec 3, ASD FieldSpec 4, and FOSS XDS and four setup features FOSS, contact probe CP, dark box DB, and open laboratory LAB at three laboratories. The application of an internal soil standard ISS to align one laboratory spectrum with another for spectral correction and spectral merging of various SSLs was examined. SOC models were developed using i data from each single spectrometer sin
