Abstract - Sustainable agriculture relies on effective irrigation management, but salt buildup in drip systems reduces efficiency and harms crops. The research introduces an automatic salt removal method using an Internet of Things (IoT)-based intelligent irrigation system. Excess salts are removed before they enter the drip lines using electrodialysis (ED) and capacitive deionization (CDI). The quality of water is measured by sensors (TDS, EC, Flow, and Pressure), while activities are regulated by an Arduino microcontroller. Monitoring and control in real-time are facilitated through a dashboard that is cloud hosted. An automatic flushing mechanism enhances durability by preventing clogging. Through the reduction of salinity by 65%, the system improved water distribution and crop health. Harvesting solar electricity enhances sustainability through reduced reliance on conventional energy. For agriculture, the process maximizes water usage, minimizes maintenance, and enhances soil condition.

Key Words: Sustainable agriculture, automatic salt removal technique, electrodialysis, capacitive deionization, Arduino microcontroller.
