4.1.10. Local Climate
Irrigation scheduling is based on three data inputs
• Soil type,
• Plant type
• Weather data
These allow calculations to be made as to when irrigation events should occur.
Rainfall must be considered when implementing irrigation schedules with practices set in
place to avoid irrigating when unnecessary i.e. after significant rainfall events.
Three ways to avoid over watering during wet periods are:
• Install rain cut off devices in parallel with the irrigation controller which cut off the
irrigation system during rain periods (most basic option)
• Install soil moisture sensing devices which over ride the irrigation controller when
enough soil moisture is present and irrigation is not needed, a simpler form of
these devices continually logs soil moisture levels and is a tool for management
to manually base irrigation event timings on (more in-depth option)
• Install and utilise an evapotranspiration (ET) system which automatically
develops an exact program to fit the requirements of each irrigation zone based
on plant species, plant maturity, soil type, slop % of surface, sun exposure,
sprinkler type and direct weather readings of rainfall, solar intensity and wind
speed. (ideal option)
