Soil scientist Guy Serbin (left) and remote sensing specialist Andy Russ calibrate a portable spectroradiometer over a white panel prior to measuring the reflectance of the crop residues and soils in a cornfield. These ground-based reflectance measurements are used to develop remote sensing tools for assessing soil tillage intensity using aircraft and satellite imagery.
