The use of NIRS sensors for mobile nutrient analysis on application equipment for liquid organic fertilizers requires quality assurance (QA) for both new and used equipment. This is a requirement of the Länder authorities responsible according to fertilizer law, in order to be able to authorize the use of NIR sensors for documentation purposes within the framework of legal regulations (e.g. fertilizer ordinance). While recognition in accordance with the test procedure of the DLG (German Agricultural Society) is a prerequisite for new devices, there is no quality assurance for devices in use yet. The aim of NIRS-QS is to define the requirements for such quality assurance, to develop and test the necessary procedural steps and to establish a practice-oriented approach in the form of procedural and work instructions as well as multimedia training forms for users.
