Spectral–Textural Feature Fusion Coupled with Machine Learning Improves UAV-Based Estimation of Maize Leaf SPAD Value in Arid Agroecosystems

Rapid and accurate monitoring of leaf nitrogen status is a key step in achieving precise fertilizer management for maize. However, UAV-based multispectral approaches relying solely on vegetation indices (VIs) may suffer from spectral saturation under dense canopies and provide limited information on canopy structural v...
