Description of practice

Drip irrigation is a method of controlled irrigation in which water is slowly delivered to the root systems of multiple plants. Water is either dripped onto the soil surface above the roots or delivered directly to the root zone. It is often preferred to flood (surface) irrigation because less water is used and lost to evaporation.

Examples of how to use drip irrigation Further information
(see Note below)

AMP51 01

Drip irrigation

Drip irrigation is used to provide a constant water supply to crops, minimizing water and labour use while improving crop growth and yield. Salinization of the soil is minimized by efficient water use.

AMP51 02

Low-cost drip irrigation

Water is precisely delivered to crops through perforated tubes. In this low-cost drip irrigation system, the pressure is supplied by connecting the tubes to a raised water tank.

AMP51 03

Polyethylene sheeting and intermittent cloth strips

Polyethylene sheeting and spaced cloth strips are used to deliver water to individual plants when poor quality irrigation water could clog nozzles.

AMP51 04

Subsurface drip irrigation

A low-pressure, high efficiency irrigation system is used in which buried drip tubes or drip tape meet crop water needs. Subsurface drip irrigation minimizes evaporation losses and reduces weed pressure.



AMP51 05

Orchard drip irrigation

A network of valves, pipes, tubes and nozzles are used in an orchard drip irrigation scheme to allow water to drip directly onto the root zone of the trees.
