Measurements of reflectance and radiant temperature of the soybean canopies were made with the Exotech 20C field spectroradiometer system and the Exotech 100 Landsat band field radiometer system at approximately 7-10 day intervals throughout the growing season. Agronomic characterizations of the canopies included: leaf area index, biomass, percent soil cover, height, development stage, and grain yield. Vertical and oblique photographs were also taken of the canopies.
