ELEVATED MICROSPRINKLER BENEFITS CITRUS TREES IN A SEVERE ADVECTIVE FREEZE [PDF]
Undertree microsprinkler irrigation has protected 1 or 2 year old trees to a height of 1 meter during severe advective freezes. During the severe December 1989 freeze, microsprinklers elevated to 0.9 meter protected 5 year old citrus trees to a height of 2 meters. Limb breakage due to ice loading was negligible.

Elevated Microsprinklers Improve Protection of Citrus Trees in an Advective Freeze [PDF]
The severe advective freeze of 23-26 Dec. 1989 killed most nonprotected trees in Florida's northern citrus region. Minimum temperatures reached - 8.3C with >43 hours below freezing. Microsprinklers elevated to a height of 0.6 or 0.9 m and placed inside the canopy of young `Hamlin' and navel orange trees ...

Performance assessment of a microsprinkler
Surface hydrological processes are essential to the understanding and prediction of soil erosion. Several equipments are used to measure infiltration rate, runoff and soil loss. However, researchers build their own equipment due to the specific sites where the measurements are performed.

Microsprinkler Irrigation Influences Clementine Fruit Quality, Leaf Temperature and Physiology
Abstract The effect on leaf physiology and fruit quality, of two irrigation schedules, daily and twice a week irrigation (control), were tested on ‘SRA 63’ Clementine (Citrus reticulata Blanco) during 2002 and 2003. Micrometeorological data revealed a higher impact of everyday irrigation on air and leaf temperature compared with the control.

Citrus Freeze Protection with Microsprinkler Irrigation during an Advective Freeze
Abstract Microsprinkler irrigation was used to protect young citrus trees during severe advective freeze conditions in Florida during 24–26 Dec. 1983. Three factors (microsprinkler distance from the tree, compass position, and water volume output) influenced the amount of protection or tree damage.
