Diagnosis of Winter Wheat Nitrogen Status Using Unmanned Aerial Vehicle-Based Hyperspectral Remote Sensing

Diagnosis of Winter Wheat Nitrogen Status Using Unmanned Aerial Vehicle-Based Hyperspectral Remote Sensing

The nitrogen nutrition index (NNI) is a significant agronomic statistic used to assess the nitrogen nutrition status of crops. The use of remote sensing to invert it is crucial for accurately diagnosing and managing nitrogen nutrition in crops during critical periods. This study utilizes the UHD185...
