mikrosprinklers

Mikrosprinklers, or micro-sprinklers, are low-flow irrigation devices that apply water through a small sprinkler head to a limited, zone-sized area. They produce a spray pattern that covers plant root zones in nurseries, landscapes, orchards, and greenhouse benches. Unlike point emitters, they deliver water as a gentle spray, which can improve uniformity on uneven ground or among closely spaced plants.

Most mikrosprinklers are fixed-spray units or micro-rotors fed by low-pressure piping. They require filtration to prevent clogging and are commonly installed on risers or under-canopy lines. Operating pressure typically ranges from about 1 to 4 bar (15 to 60 psi), with flow rates from roughly 0.1 to 2.5 gallons per minute per head. Coverage radii vary by model, usually from 1 to 6 meters.

Advantages include lower water use than full-coverage sprinklers, reduced evaporation, and suitability for irregular beds or potted crops. They provide localized application with better root-zone penetration. Limitations include vulnerability to clogging, wind drift in exposed sites, and the need for regular maintenance of filters and screens.

Design and maintenance considerations emphasize matching sprinkler spacing to crop water needs and pressure availability. Regular maintenance involves cleaning filters, flushing lines, inspecting for leaks, and replacing worn heads. In greenhouses, mikrosprinklers are often used with controllers and soil or moisture sensors to optimize irrigation.
