The FIGARO decision support system combines crop growth models with data from satellites, weather stations and field-based sensors to recommend optimal water use for individual fields. Most data input is automatic, minimising the set-up time farmers spend with the application.

Advice is calculated on a processing platform that was designed to work with a wide range of crop models and data sources. This gives users the flexibility to start with a small investment in the basic decision support technology, then add sensors and other data sources later for more precise irrigation strategies.

Estimates from the project suggest that the system can save 20-60% of users’ irrigation water for the same yield of crop, with a starting investment of €5-20 per hectare. The exact saving depends on the season and other variables. The system can also help reduce fertiliser use. Precise irrigation keeps nutrients around plants’ roots and avoids them flowing away or penetrating the deep soil in excess water, which can occur in over-irrigation.

As well as boosting the sustainable use of resources and cutting pollution, the FIGARO system can make it easier for farmers to comply with EU rules on water productivity and help policy-makers monitor farming practice.
