ATS-ECLO1, is an innovative device to reduce the inputs minimizing yield loss. This agro-ecological approach, following the European 676 / EEC Directive 91 /, has the following objectives:  Reduce and control pollution of water  Improve yield and protein content of cultures  Evaluating real-time flow of nitrates in the soil-plant transfer zone (rhysosphere) To achieve these goals, ATS-ECLO1 focus on two major issues:  Bring the appropriate dose at the right moment for the plant growth  Optimize the establishment of the next crop or intermediate crop trap nitrate The technical solution consist in a network of underground sensors and associated web applications based on FIWare technologies. This is used to assess in situ and continuous cropping potential of agricultural soil by an automated method of monitoring the flow of nitrates. Impacts : • Decrease water pollution by nitrates • Improve yield and protein content of crops by monitoring • Optimize the economic performance of farms by reducing the cost of treatment • Integrate and benchmark data at the regional level for cooperatives and institutions The final module will be connected to web and mobile apps and API and facilitate the crop fertilization for farmers. Indeed, European cereal producers farmers and vegetable crops as well as agricultural cooperatives and food processing industries could benefit from this new system to optimize nitrogen inputs on the soil.
