Micro-Sprinkler Irrigation
Also known as: Micro-jet irrigation, Micro-spray irrigation
Micro-sprinkler irrigation applies water through small, low-pressure sprinkler or spray heads set close to the crop, wetting a limited area around each plant or a strip along the row rather than the whole field surface.
Micro-sprinkler systems use small emitters mounted on stakes or risers that spray water over a partial- to full-circle pattern at low pressure and flow, wetting a defined area around each plant. They are commonly used as an alternative to drip in orchard and vineyard row crops, where a wider wetted area or additional benefits such as frost or heat mitigation are wanted.
Micro-sprinkler irrigation differs from drip irrigation in wetting a surface area through spray rather than delivering water at a fixed point, and it differs from conventional sprinkler irrigation in its much smaller wetted radius, lower flow rate, and lower operating pressure aimed at each plant rather than the whole field.
How it works
- Water is filtered and pressure-regulated before entering the distribution network
- A mainline and laterals carry water to individual field sections
- Micro-sprinkler heads mounted on risers or stakes are positioned near each tree or plant
- Each head sprays water over a defined radius rather than a single point
- Soluble fertilizer can be injected into the system (fertigation) alongside irrigation
Where it suits
Micro-sprinkler irrigation suits orchard and vineyard crops and other widely spaced perennial plantings, including situations where a larger wetted radius aids the root development of newly established trees.
Efficiency and management
Because water is sprayed over a wider surface than a drip emitter's point delivery, micro-sprinkler application efficiency is generally somewhat lower than point-source drip, with more surface exposed to evaporation, but it remains higher than full-field sprinkler methods. Matching output to crop water demand through scheduling is still necessary to realize efficiency gains.
Considerations
As with drip systems, filtration and periodic maintenance are needed to prevent emitter clogging from sediment or mineral precipitates.

Scope & limitations
Geographic scope: Used across orchard and vineyard production worldwide; suitability and design depend on local water quality, crop spacing, and climate.
Climate context: Some micro-sprinkler systems are used for frost protection or evaporative cooling in orchards, in addition to routine irrigation.
