PORTABLE APPARATUS FOR SOIL CHEMICAL CHARACTERIZATION

摘要

The present invention determines one or more properties of a soil sample by scanning a soil sample using a visible near infrared diffuse reflectance (VisNIR) spectroradiometer, scanning the soil sample using a x-ray fluorescence (PXRF) spectrometer, receiving a diffuse reflectance spectra from the VisNIR spectroradiometer and an elemental data from the PXRF spectrometer, determining one or more properties of the soil sample using one or more processors and a predictive model that relates the diffuse reflectance spectra and the elemental data to the one or more properties, and providing the one or more properties of the soil sample to one or more input/output interface.
