Abstract

Automatic irrigation controls, such as gates, checks, valves, timers, soil
moisture sensors and related devices, are described. These increase worker
productivity and give better control of farm irrigation water. Most semiautomatic
irrigation systems use mechanical timers to control irrigation
and its duration, whereas automatic systems use sensors and programmed
timers. Automatic and semi-automatic gates and checks are used in open
channel systems to divert water through different kinds of openings. Low
pressure valves and controls are being developed and tested for automating
gated pipe systems.
