Definition - What does Drip Irrigation mean?
Drip irrigation is a method of controlled irrigation in which water is slowly delivered to the root system of multiple plants. In this method water is either dripped onto the soil surface above the roots, or directly to the root zone. It is often a method chosen over surface irrigation because it helps to reduce water evaporation.
MaximumYield explains Drip Irrigation
Drip irrigation is delivered to plant roots through a series of pipes, tubes, and valves. These parts, controlled by emitters and pumps, allow water to be focused in a particular area. In addition, drip systems can incorporate liquid fertilizer into the irrigation water.
Drip irrigation systems can help reduce evaporation and runoff, and contribute to water conservation. However, before this system can work correctly it must be properly installed and managed.
The two main types of drip irrigation are:
- Surface drip irrigation - The water is delivered to the surface of the soil directly above the root system of the plants. This particular type of drip irrigation is mainly used on high-value crops.
- Subsurface drip irrigation - The water is applied directly to the root system. This type is used particularly in growing row crops.
