Developed by TerraNIS, the Pixagri Irrigation service is a decision-support tool designed to maximise crop potential by enabling users to carry out their irrigation cycles at the right time, should there be a risk of water stress on their plots. It is aimed at players in the agricultural supply chain (agricultural co-operatives and agricultural suppliers), seed companies and agri-food businesses. All of these stakeholders have a common interest in monitoring water stress on their plots, given the increase in drought events and the growing number of water restrictions.
The tool is based on a water balance model and integrates field data (plot boundaries and available soil analyses), combined with meteorological data and satellite data (Sentinel-2 to date, with Trishna or LSTM data to be used in the future). Available via a web interface and mobile app, its aim is to provide irrigation recommendations in millimetres in the event of a risk of water stress – estimated on a daily basis – on agricultural plots.
An evolution of the service, integrated into the Pixagri Irrigation commercial offering and utilizing thermal infrared data, is being developed as part of the CNES’s ‘Ambition aval’ programme (2025–2026). Data from Trishna will provide a crop evapotranspiration value derived from observational data, enabling better calibration and adjustment of the model’s outputs. The ultimate aim is to move towards targeted irrigation.
