A known method of accurately measuring the spectral properties of soil is with a laboratory spectroradiometer. The Landsat satellites can also measure spectral properties of nonvegetated soils. In this study, Landsat‐l spectral measurements of 16 selected soil sites were adjusted for atmospheric effects and compared to spectroradiometer measurements, considering the spectroradiometer to be a reliable reference. Landsat radiance and spectroradiometer reflectance values were highly correlated for all Landsat wavelength bands. Analysis of variance showed that these 16 soils, consisting of 11 soil series, could be separated into five spectrally distinct groups on the basis of surface color and into four groups on the basis of series characteristics.
