What FIGARO was
Aims and context of the project.

EU FP7 research project · 2012–2016 · precision irrigation
FIGARO (Flexible and Precise Irrigation Platform to Improve Farm Scale Water Productivity) was a European research project that ran from October 2012 to September 2016. Its goal: help farmers irrigate with less fresh water by combining field sensors, weather forecasts and crop models in one decision-support platform.

This site is an independent record of that work: what the platform did, where it was tested, what was published and how precision irrigation has been discussed since. It is not the project's official website.
Aims and context of the project.
Sensors, models, optimisation: how the system worked.
Field tests and public deliverables.
Brussels, 19 September 2016.
Tensiometers, granular matrix blocks, capacitance and TDR probes: what each type of soil moisture sensor actually measures, how its readings turn into an irrigation decision, and the installation mistakes that make a good sensor give bad advice.
How distribution uniformity, emission uniformity and Christiansen's coefficient are measured in the field, what makes a drip system drift out of balance, and why precise scheduling is wasted on an uneven system.
How the FAO-56 method turns weather data into a crop water requirement: reference evapotranspiration, crop coefficients by growth stage, the soil water balance, and where the method needs field measurements to stay honest.
