Cross-Field Transfer of UAV-Based Winter Wheat Yield Prediction: Model Transferability and Sample Efficiency

Unmanned aerial vehicle (UAV) remote sensing is widely used for plot-scale crop yield prediction, but model performance may decline when models are transferred across fields with different crop, environmental, management, and sensing conditions. This study evaluated the cross-fie...

Evaluating mobile drip irrigation as a water-saving alternative to center pivot irrigation for large-scale alfalfa production

Mobile drip irrigation (MDI) has been proposed as a retrofit option to improve the water productivity of center pivot irrigation (CPI) for water-limited alfalfa production. However, how differences in root-zone soil water dynamics, inter-row soil evaporation, and short-term sap f...
