Precision Irrigation Management Using Modelling and Remote Sensing Approaches

To attain the goal of optimum water and nutrient use efficiency, precision irrigation management uses the most effective irrigation techniques. For precision irrigation management, it is crucial to comprehend spatial field variation. As a constant and user-friendly source of data, satellite sensors and remote sensing technology have the potential to improve water management in irrigated areas and estimate crop water demand. Crop simulation models are used in irrigation management and crop production, and they have shown to be quite helpful in improving knowledge of the functioning of agricultural systems. Crop models running in real time can furnish data on irrigation development and yield progression of the crop. As a new technique for managing precision irrigation, a synergy between remote sensing and crop simulation models can be suggested.
