Multidisziplinäre Untersuchungen zur nachhaltigen Stickstoffdüngung unter Berücksichtigung der Möglichkeiten der satellitengestützten Präzisionslandwirtschaft

In the H2020 project FATIMA (FArming Tools for external nutrient Inputs and water MAnagement) an integrated approach for the optimisation of nitrogen management in agriculture was applied. In addition to the technical component, which included the processing of Sentinel-2 satellite data, the socio-economic and agronomic aspects of improved nutrient management were investigated. The results show that farmers are mainly interested in timely application maps for variable-rate nitrogen application. In the course of the project not only a field trial for the validation of satellite data as a basis for an economic analysis was established, but also an online application for site-specific fertilisation based on current and historical satellite images was developed and tested.
