Various image sensor technologies provide the data, in the most common case from a visible light digital camera. [15] Fluorescence imaging is also used in plant health monitoring – demonstrated by Ning et al. 1995 in very early diagnosis of herbicide injury and attack by fungal plant pathogens.

It is used in conjunction with irrigation sprinklers to form an automated or non-automated sprinkler system, capable of administering precise amounts of water, at a regular basis. A water flow timer using a ball valve contains an electric motor with gears to stop or start the water flow by turning a perforated ball within the water flow line.
Passive sub-irrigation, also known as passive hydroponics, semi-hydroponics, or hydroculture, [51] is a method wherein plants are grown in an inert porous medium that moves water and fertilizer to the roots by capillary action from a separate reservoir as necessary, reducing labor and providing a constant supply of water to the roots. In the ...
Irrigation scheduling is the process used by irrigation system managers to determine the correct frequency and duration of watering. The following factors may be taken into consideration: Precipitation rate of the irrigation equipment – how quickly the water is applied, often expressed in inches or mm per hour.
Distribution uniformity or DU in irrigation is a measure of how uniformly water is applied to the area being watered, normally expressed as percentage, and not to be confused with efficiency. [1] The distribution uniformity is often calculated when performing an irrigation audit. The DU should not be confused with the coefficient of uniformity ...
Vital articles is a list of subjects for which Wikipedia should have corresponding high-quality articles. It serves as a centralized watchlist to track the status of Wikipedia's most essential articles.
In the early 1930s, a farmer drew his attention to a big tree, growing in his backyard "without water". After digging below the apparently dry surface, Simcha Blass discovered why: water from a leaking coupling was causing a small wet area on the surface, while an expanding onion-shaped area of underground water was reaching the roots of this particular tree—and not the others.
