How to use the Irrigation
Calculator
This calculator uses the monthly water budget method
of irrigation scheduling. It relies on historical information of local
monthly evapotranspiration of a reference crop (grass or alfalfa). This
information is commonly available from Ministry of Agriculture or Extension
offices. For British Columbia this information is available at the Farmwest
web site.
The following is a brief description of the irrigation calculator.
Identification Information |
This information identifies your company, your client,
the irrigation zone, and the calendar month for which this schedule
was developed. |
Reference Evapotranspiration |
The evapotranspiration of the reference crop. This will be stated
in your Ministry of Agriculture source information. |
Landscape Information |
Information about the vegetation in this irrigation zone. The terminology
used in the "Planting Type" pull down menu refers to ornamental
plants, but is easily transferable to agricultural crops. |
It is not necessary that you submit your information
at this point. If you do the calculator provides you with the monthly
evapotranspiration from your landscape. This information is primarily
useful for irrigation system designers. |
Soil Information |
The appropriate information for the soil in this irrigation zone.
The higher the allowable water deficit %, the more the soil is allowed
to dry out between irrigations. |
| It is not necessary that you submit your information
at this point. If you do the calculator provides you with the infiltration
rate of your soil, the amount of water available in the root zone
of your vegetation, and the amount of irrigation required. |
Irrigation equipment |
Select the equipment and whether watering restrictions apply.
Then submit the information.
A new screen will ask for information about the watering restrictions
and the irrigation system. |
When you submit this information the calculator provides
you with your irrigation schedule.
Please note: the proper interpretation of the results supplied
by this calculator is described in the Irrigation
Scheduling, Organic
Turf Management and Organic
Landscape Management programs. It is essential that you understand
the source documentation used by the calculator if you intend to
use the results provided by it. |
