Irrigation scheduling

Irrigation scheduling is all about applying the right amount of water, at the right time, to satisfy a particular crop's needs. Various scheduling options are listed within this section. Additionally, irrigators need to be aware of the potential for soil salinity levels to increase as a result of inappropriate irrigation management practices. Management options to minimise this potential, or prevent this situation from occurring, are presented below.

Evapotranspiration (ETo) data

A term for combined water loss due to evaporation (e.g. from soil and water bodies) and transpiration (from plants). Locally relevant ETo figures can give irrigators an indication of total atmospheric waterloss associated with their locality. Incorporating evapotranspiration (and crop coefficient) information into appropriate formulas can give irrigators an indication of how much to apply during the subsequent irrigation event.

Irrigation Scheduling Tools

The following irrigation scheduling tools incorporate a number of inputs within Excel spreadsheets (including ETo, rainfall and information from past irrigation events) to provide the irrigator with a figure of how much to apply during the next irrigation event.
