An irrigation system is used to water the plants and grass. There is little to no manual intervention besides the surveillance and auto-control that manages everything when it comes to the automatic irrigation systems. Almost anything like a drip, sprinkler, or surface can be automated with this automatic irrigation system. This is done with the help of various electro-mechanical equipment like sensors, timers, computers, and other mechanical appliance.
Thus a gardener can spend more time on the other farming tasks as the irrigation will be handled by the automatic control systems, which will make it far more efficient. Though some systems can be quite expensive and complicated, you can find affordable ones as well.
An affordable irrigation system ensures that your lawn and plants remain green, and at the same time, you do not spend all of your saving on buying an expensive one. Automatic irrigation systems have the below advantages:
- The ability to set a schedule for your irrigation system to start. This way, you become the boss of the controller, which is a small computer that manages the activation of your irrigation system and also checks the time at which it should be switched on and off. More information can be found in the article.
- These irrigation systems also possess moisture and rain sensors that sense if it is raining or if the soil is dry. In these cases, the irrigation system will not start for the rainy case but will start if the soil is dry. This ensures the plants and lawn remains green at the same time there is no wastage.
- There is also a possibility in some irrigation systems to change the frequency of irrigation that optimizes and minimizes wastage.
- Some systems also can operate it at night, so there is no problem with evaporation.
- Also, the energy used is minimized as the system starts and stops exactly when required.
There are a variety of irrigation systems that can be automized. This classification depends on how the water is distributed throughout the stretch of the field.
- Surface irrigation – There is no mechanical pump involved, and the water is distributed solely by gravity.
- Localized irrigation – This is a low-pressure irrigation system wherein a piped network is used, which is taken to each plant.
- Drip irrigation – This type minimizes evaporation and run-off and is localized irrigation where water is delivered as drops at or near the plant roots.
- Sprinkler irrigation – This type uses overhead sprinklers or guns using high-pressure from a central location in the area, or the sprinklers have moving platforms.
- Center pivot irrigation – Water is distributed by a system of sprinklers moving on wheeled towers in a circular pattern, which is quite common in flat regions.
- Lateral move irrigation – This type infuses the use of a series of pipes wherein each has a wheel and a set of sprinklers, which use a manual or a purpose-built rotating mechanism. This system is less expensive but tends to involve more labor than the others as the sprinklers will move a certain distance, but for the next distance, the hose will have to be reconnected.
