1. Predicting of Canopy Nitrogen Content Based on UAVs and Satellites Data Fusion in Citrus Orchards

Nitrogen (N) is often regarded as the most critical nutrient and the growth-limiting factor in soil for ‎‎plant growth and often needs to be supplemented by N-fertilization to minimize yield ‎‎loss. However, the over-application of N fertilizers may cause nutrient imbalance ‎and contribute ‎to groundwater ‎contamination by nitrate (NO3-) leaching and NOx air pollution. Today the ‎evaluation of plant ‎nutritional status (including ‎N... A. Dagan
