1. In-season Nitrogen Management for Wheat in Tunisia Using Proximal and Remote SensingWhile the cereal sector represents an important factor in the social and economic farming structure in Tunisia, the national wheat average yield is very low, estimated to 1.4 t/ha. However, the frequent spreading of nitrogen in large quantities to raise yields can lead to low use efficiency of N and groundwater pollution. In Sweden, digital tools using proximal and remote sensing for variable rate application (VRA) of nutrients were developed and widely used by farmers to optimize fertilization... M. Mechri, O.

2. A 3D Camera-based Fertilizer Residue Monitoring System with Isobus for Precision AgricultureAccurate monitoring of fertilizer usage is critical for effective variable-rate fertilization (VRF), contributing to optimized nutrient management and environmental sustainability. VRF systems typically use open-loop control based on prescription maps and calibration data. However, this approach can introduce discrepancies between targeted and actual fertilizer application rates due to variations in fertilizer characteristics and environmental conditions. This study proposes a fertilizer hopper... C. Yun |
