The calculation replaces estimated water use for the last completed day(s). It assumes the last full irrigation restored field capacity.
User responsibility
By using IrriSense, you agree that you are responsible for verifying the inputs and results and for any irrigation decisions or actions taken based on them. Results are estimates and must be checked against actual field conditions before use.

Automatically updates after changing your inputs.

Clear your entries and results, then start again from field location.

Advanced settings & manual weather
Soil is an editable estimate, not extracted from the pin. Root depth and crop-stage lengths need local verification.

Assumptions & calculation limits

FAO-56 crop-coefficient planning calculator. ET₀ comes from Open-Meteo or your manual entry. Past weather values may be modeled, not measured on the field. Annual crop-stage durations are illustrative; mature citrus and coffee use simplified constant coefficients.

Assumes field capacity at the last full irrigation, rain infiltrates before daily ET, no runoff, no capillary rise, and constant active root depth. Where modeled water stress occurred, the refill depth is capped by available soil storage. Reported time does not include a separate salinity leaching requirement.

Results are estimates, not automatic valve commands. SoilGrids and weather-station triangulation are not connected.
