Abstract: This dissertation investigates algorithms and a cloud-based spatial data infrastructure (SDI) for the site-specific management of water and nutrients based on sensor data. An open-source SDI integrated sensor data, maps, and decision-support outputs within an OGC/ISO-compliant framework. A Python-based DSS automatically generated fertigation maps for a hose-reel irrigation system. Field trials in Germany, France, and Turkey demonstrated the feasibility of the developed system.
