Bestimmung der Inhaltsstoffe bei der Ernte mit dem Feldhäcksler

Near-infrared spectroscopy (NIRS) can be used to assess forage quality. Rugged NIRS sensors make it possible to use them on agricultural machines. Until now the calibration of these sensors was specifically designed for the respective machines and operating conditions. For use in agriculture alternative calibration methods are needed. One possibility is to gather a wide variance of content concentrations through experimental cultivation with specific variety selection and fertiliser application. The calibrations would then be determined in the laboratory. In order to transfer the calibrations from the laboratory to various choppers, the effects of the different samples were investigated.
