Changes in spectral response of a Waukegan silt loam soil were induced by variable tillage and crop residue management on replicated plots. Variable random roughness had little effect on spectral response in the Thematic Mapper bands. Differential weathering of these soil surfaces was spectrally evident over time. Crop residue type and amount had significant effects on spectral response when the surface coverage exceeded 35%. Changes in soil scene spectral response caused by management must be better understood in order to apply remote sensing technology to large scale soil survey and soil erosion studies.-AuthorsUniv of Minnesota, Soil Science Dept, St. Paul, MN, USA.
