Estimation of Nitrogen Vertical Distribution by Bi-Directional Canopy Reflectance in Winter Wheat
Timely measurement of vertical foliage nitrogen distribution is critical for increasing crop yield and reducing environmental impact. In this study, a novel method with partial least square regression (PLSR) and vegetation indices was developed to determine optimal models for extracting vertical fol...
