Georeferenced sensor-supported data management system for a site-specific irrigation and fertilisation of open field vegetablesWithin the framework of GeoSenSys, a web application will be developed which gives the user recommendations for action on site-specific N-fertilisation and irrigation, based on geographic information systems (GIS).

Intelligent control systems will combine information on soil characteristics, C-N dynamics, crop development, fertilisation and irrigation requirements and then visualise it for user decisions as a browser-based web application.

Maps with variable irrigation rates and N-fertilization will be generated to provide site-specific management recommendations for both factors. The development of decision support system based on neural networks, which can estimate the water demand on the basis of measured soil, plant and environmental parameters, is of particular scientific interest.In order to be able to couple decisions on N-fertilisation and irrigation, a mineralisation model will be developed and linked to a water demand model.The modelled water demand will be checked with evapotranspiration measurements (eddy covariance), the modelled N demand with Nmin samples and results will be evaluated in practice.
