ShaukatS.S. of Estimating nonharvested crop residue cover dynamics using remote sensing ed. The main objective of this study was to investigate the potential of remote sensing to assess residue coverage. The research showed that surface reflectance was more closely correlated with percent cover than the amount of residue returned. Of the spectral band widths measured, reflectance in the blue range provided the most consistent results across the two years. NDWIw had a higher correlation with residue returned and % cover than NDVIw, GNDVIw, or BNDVIw. Future studies should not only consider more field sites, but incorporate factors such as the decomposition rates of residues on spectral reflectance and harvesting approaches (see Daughtry et al. 2010), so as to develop an accurate and standard approach for mapping residue cover in real time over large geographic areas.
