Winter Wheat Nitrogen Estimation Based on Ground-Level and UAV-Mounted Sensors
A better understanding of wheat nitrogen status is important for improving N fertilizer management in precision farming. In this study, four different sensors were evaluated for their ability to estimate winter wheat nitrogen. A Gaussian process regression (GPR) method with the sequential backward f...
