摘要：

Crop models are key tools for helping in decision making in the frame of precision agriculture. However they need a site specific calibration in order to give coherent spatial representation of crop and soil state variables that can be used to make diagnosis and allow recommendations. This paper shows how to perform such a calibration, using the assimilation of external information on crop status obtained from remote sensing images. The improvement in model simulation was evaluated through the improvement in the final yield map estimation.
