Spectral reflectance measurements for organic matter sensing in Saskatchewan soils

Authors: H.R. Ingleby and T.G. Crowe
Description: Diffuse reflectance spectra from 250 to 2500 nm were measured for soil samples taken from five Saskatchewan fields. The five fields represented a range of organic carbon levels varying between 0.55 and 5.34%. The efficacy of two previously published equations relating reflectance values at specific wavelengths to the soil organic carbon content was evaluated using these data. While one method resulted in a coefficient ofdetermination (r) greater than 0.8 for all samples, neither method was suitable for implementation in a soil organic matter sensor. Further investigation into methods for determining an optimum wavelength set for organic carbon prediction in Saskatchewan soils is recommended.
