1 Near-infrared spectroscopy on plot harvesters Peter Tillmann, DLU Kassel Christian Paul, L Braunschweig

2 Back ground Field trials with high demand for information regarding composition NIRS applications on fresh products (grass silages, meat, whole meals) Integrating NIRS into the harvest process (NIRS onboard)

3 Field trials grass, forage trials forage maize trials grains and rapseed trials forage harvester chopper plot combine harvester

4 The beginning forage harvesters: Rode and Paul, L ( first field test 1999) Kormann, TU München (2001) maize choppers: Femenias, Limagrain and Dardenne, CRAGX (1998) Welle, Pioneer (1998) plot combines: Femenias, Dardenne, Welle (1998) Reyns, KU Leiden (2003) Rademacher, Uni Kiel (2003)
