Description :
The aim of this study was to evaluate the potential of multi-spectral aerial imagery and topographic information for assessing topsoil organic matter (SOM) content based on detailed surveys carried out in 2 spatially and geologically independent Danish fields. The results show that the spectral reflectance data obtained within the visible and near infrared range are correlated with the SOM content in both fields, and that the spectral bands are almost co-linear. The results also revaled that the data used in the investigation were insufficient to properly describe the variations of SOM within the fields.
