Agriculture requires the collection, storage, sharing and analysis of large quantities of spatially referenced data. Management of huge amounts of data is a challenge. The aim of the Ground Water and Meteo sensors experimentation is to develop a Web based system for integration, transformation and utilization of large quantities of data and models for agrometeorological and groundwater measurement. The technology will provide insights on precise climate conditions and vegetation status. This information will be used to give recommendations for fertiliser application during the season and to plan other necessary interventions.
