The increasing demand for agricultural water by utilizing real-time sensor data, modern technologies such variable rate irrigation (VRI) and precision irrigation (PI) enable the effective and precise application of treated wastewater. These developments reduce environmental risks such as runoff and groundwater pollution, maximize water use, and enhance fertilizer delivery. Emitter clogging is a frequent issue in drip irrigation, which is vital in the campaign for worldwide water scarcity. It reduces crop yields by conflicting in irrigation uniformity and system performance. This problem is exacerbated by the use of salt water in fertigation, highlighting the need for innovative methods to prevent blockages. Irrigation management is being transformed by automation, which is being propelled by developments in artificial intelligence, robots, sensors, and cloud computing. With web dashboards, farmers can now remotely operate water pumps and keep an eye on variables like soil moisture content and flow rates. In conclusion, modern wastewater method of irrigation enables safe, efficient, and environmentally friendly water management, which is crucial to maintaining in natural resources and sustainable agriculture.
