IrriSAT review
Free field-level water estimates and daily irrigation guidance, without automated control.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
IrriSAT is a web-based irrigation decision-support service from Deakin University for farmers who want crop-water estimates to inform irrigation planning. It combines satellite imagery with nearby weather-station observations to estimate crop growth, crop water use and irrigation needs. Users can define and manage custom fields, then view crop-coefficient maps and time series. The service is free and suited to small growers who can use estimates to guide decisions rather than expecting software to operate irrigation equipment for them.
Its core strength is field-level water information. IrriSAT displays NDVI and crop coefficient (Kc) maps, provides daily irrigation information and calculates seasonal daily crop water use for defined fields. A water-balance approach tracks soil-water deficit over time; users can configure the initial deficit and refill point, along with field settings such as planting dates. This supports planning around crop conditions and water balance, but the product stops short of turning those estimates into automated actions. Growers seeking remote control or automated scheduling will need a different tool or a separate system for those tasks.
IrriSAT runs in a browser on desktop and mobile devices, but it is not a mobile app. Fields can be shared with other IrriSAT users, which may help when irrigation decisions involve collaborators. Support is available through email and documentation. The published description presents the service as free, with no paid tier described. That makes it a focused option for growers who need satellite-based estimates and field tracking without a software fee; operations that need equipment control, automatic schedules or a dedicated mobile application should look elsewhere.

- Maps NDVI and crop coefficient (Kc) across defined fields
- Tracks soil-water deficit with configurable refill points
- Where it doesn't
- Does not provide remote irrigation control
- Does not automate irrigation scheduling
- Available as a web service, with no mobile app
