Sprinkler irrigation : The application of water to the soil for the benefit of present crops. Water is projected outward through the air by above-ground applicators to reach the soil in droplet form that approaches rainfall. Applicators commonly used are rotary or fixed sprinklers, oscillating pipe or perforated pipe.  3, fiche 1, Anglais, - fixed%20spray%20sprinkler

Sprinkler irrigation. Basic sprinkler types include rotating sprinklers and stationary spray-type nozzles. Rotating sprinklers, such as the slow-rotation, impact-driven sprinkler, are most commonly used. Fixed-spray nozzles are becoming more popular, although they are used most often for landscape applications because their application rates are very high.  5, fiche 1, Anglais, - fixed%20spray%20sprinkler

nozzle. As per the source Internet, www.aom.ufl.edu/aom3734/handouts/Lecture12.doc, a "nozzle" is one part of a "sprinkler" but in other consulted sources, the term is also used as the whole.  7, fiche 1, Anglais, - fixed%20spray%20sprinkler

L'appareil à basse pression le plus fréquemment utilisé pour l'irrigation en grande culture est l'asperseur [...] qui est un ajutage avec ou sans brise-jet, piqué sur la canalisation ou placé à l'extrémité d'un support vertical; il peut être fixe ou muni d'un dispositif à palette oscillante qui, sous l'action du jet, provoque la rotation de l'appareil.  2, fiche 1, Français, - arroseur%20fixe

Irrigation par aspersion [...] Elle comprend de nombreuses techniques qui diffèrent par : - la nature de l'asperseur : à jet fixe (diffuseur) ou à jet rotatif. [...] - le fonctionnement de l'asperseur à poste fixe ou en déplacement (appareil à pivot central, canon automoteur).  5, fiche 1, Français, - arroseur%20fixe

Irrigation by means of underground open joint tile, perforated pipes, or open ditch to maintain the water table at a desired distance below the ground surface.  4, fiche 2, Anglais, - subsurface%20irrigation

Water is applied to crops by surface, subsurface, sprinkler, and drip irrigation... Subirrigation. This type of irrigation is accomplished by raising the water table to the root zone of the crop or by carrying moisture to the root zone by perforated underground pipe.  5, fiche 2, Anglais, - subsurface%20irrigation

Record number: 2, Textual support number: 1 OBS

Subirrigation (seepage) systems are based on establishment and maintenance of the high water table just beneath the crop root zone. Due to the capillary action the water migrates upward providing necessary moisture for the crop. For this system to function, the top layer of soil must have high hydraulic conductivity typical for sand or muck. The existence of natural high water table or restrictive layer (clay, rock, etc.) below the root zone is necessary to allow for the buildup and regulation of the irrigation water table throughout the season. Raising the water table in addition to providing for the evapotranspirational demand of the crop, requires large quantities of water which must also be available for seepage irrigation.  6, fiche 2, Anglais, - subsurface%20irrigation

The one major fault of the perforated pipe irrigation system is its use of large quantities of water. This could possibly be reduced by using non-perforated pipe and manually drilling holes in the pipe adjacent to the plants. This would allow the pipe to fill faster due to the reduced number of outlets, and would direct the water to only where it was needed. It is recommended that for restoration efforts that allow a water source such as a water truck to be used, perforated pipe be selected as the means of irrigating the seedlings.  1, fiche 3, Anglais, - perforated%20pipe%20irrigation%20system
