The use of NIR sensors for on-the-go nutrient analysis on slurry tankers requires reliable quality assurance (QA) systems for new as well as for devices already in use. This is a requirement of the federal state authorities responsible for all aspects related to use of fertilizers in order to be able to permit the use of NIR sensors for documentation purposes within the framework of legal regulations (e.g. the German fertilizer ordinance). While for new NIR sensors a quality check according to the DLG test procedure is a prerequisite for market access, there is no QA system available for those devices already in use. The aim of the NIRS-QS project is (1) to define the requirements for such a QA system, (2) to develop and test the necessary procedural steps and (3) to establish a hands-on approach for teaching materials and working instructions as well as multimedia training materials for users.
