Engineering referenceIrrigation Schedule Calculator
Convert crop water demand and sector runtime into a transparent weekly irrigation schedule.
Calculation method
Weekly demand is distributed over the selected irrigation days. Sector events are sequenced from the chosen start time using the calculated duration.
Formulas used
Volume per irrigation day = daily demand × 7 / irrigation daysEvent duration = sector volume / sector flow
Worked example
A 35 m³/day average demand irrigated three days per week requires about 81.7 m³ on each irrigation day.
How to interpret the result
Confirm that events fit source availability and revise frequency when soil storage or crop stress does not support the interval.
Common mistakes
- Treating a weekly average as a weather forecast.
- Scheduling beyond available pumping hours.
- Ignoring soil storage and allowable depletion.
Scope and limitations
- The schedule is deterministic and does not ingest live weather, soil moisture or controller data.
Frequently asked questions
Is this a weather-based controller?
No. It schedules the data entered by the user and exposes every assumption.
Can irrigation run every day?
Yes, if selected and compatible with agronomic and operational constraints.
Why can the schedule exceed the available window?
Required volume, sector flow or sector count is incompatible with the entered time window.
