![]() ![]() The Illinois fields (SW and NW) were high in soil minerals, OM,Īnd soil electrical conductivity. The FO field had the highest average reflectance, followed by SW, GV, and NW. The VIR images were geo-registered and calibrated into apparent reflectance values. ![]() Field data included hyperspectral VIR images and soil fertility parameters including pH, organic matter (OM), Ca, Mg, P, K, and soil electrical conductivity. two fields (GV and FO) in Missouri were considered in this study. In this study, we have explored the potential of aerial visible/infrared (VIR) hyperspectral imagery for characterizing soil fertility factors in midwestern agricultural fields. Resolution that are ideally suited for precision agricultural applications. Airborne hyperspectral images provide high spatial and spectral resolution along with flexible temporal ![]()
