Performance of Field-Scale Lab vs in Situ Visible/near- and Mid-Infrared Spectroscopy for Estimation of Soil Properties

Abstract Comparison of laboratory versus in situ visible/near- (visNIR) and mid-infrared (MIR) spectroscopy for prediction of various soil properties is required to demonstrate trade-offs between accuracy and efficiency. Field measurements were made …

Performance of in Situ vs Laboratory Mid-Infrared Soil Spectroscopy Using Local and Regional Calibration Strategies

Comparison of in situ mid-infrared spectroscopy (MIRS) with laboratory MIRS is required to demonstrate the accuracy of field-scale prediction of soil properties. Application of MIRS to investigate soil management questions must also be tested. Our …

Quantification of Soil Organic Carbon at Regional Scale: Benefits of Fusing Vis-NIR and MIR Diffuse Reflectance Data Are Greater for in Situ than for Laboratory-Based Modelling Approaches

Benefits of fusion approaches for visible to near (vis-NIR) and mid-infrared (MIR) chemometric modelling have been studied to some extent for laboratory-based soil studies, but little is known about the usefulness and limitations for in situ studies. …
