Automatic irrigation is the use of a device to operate irrigation structures; therefore, it is possible to change the flow of water from one bay or into one of the bays in the absence of irrigation.

Automation can be used in various ways:

• Starting and stopping the irrigation system via supply channel outlets,
• Starting and stopping pumps,
• These automations can be used to cut off water flow from an irrigation area, i.e., a bay or a section of a canal, and direct the water to another area.

These changes occur automatically without any manual effort. However, the producer must be at the system while preparing the system at the start of the irrigation process and performing maintenance for the components to function properly.

The benefits of automatic irrigation are many and are listed below:

✓ Reduced labor: Since the producer does not need to constantly monitor the progress of an irrigation, the irrigation system can be used to perform other tasks without interruption.

✓ Improved lifestyle: The producer does not need to constantly check the progress of the water under the bays being irrigated. The producer can stay outside the property and catch the opportunity to spend more time with their family.

✓ More timely irrigation: Producers with automation can irrigate with as much water as the plant needs and when it needs it.

✓ Helps in the management of higher flow rates: Many producers want to increase the irrigation flow rates they receive by installing larger canals and bay outlets. Such flow rates usually require an increase in labor as the time taken to irrigate a bay is reduced, therefore, more frequent changes are required. Automation allows these high flows to be managed without an increase in the amount of labor.

✓ More precise cutoff: Automation of the irrigation system ensures that water is cut off at the appropriate point in the bay. This is usually more accurate than manual control because water losses occur when producers are too late or too early to make a change in water flow.

✓ Reduced runoff of water and nutrients: Automation can help with both effective fertilization and spraying by reducing water losses. Retaining fertilizers and pesticides in the land to be irrigated provides both economic and environmental benefits.

✓ Reducing the cost of vehicles used in irrigation: Since the producer does not need to constantly check the progress of an irrigation, transportation and other road expenses between the land and the farm are reduced, which lowers operating costs.
