Validating and adapting regional soil maps for precision agriculture

Abstract

A remote sensing-based method for digital soil mapping of texture and organic matter content has been developed in an area with variable geology around Kvänum in central Sweden. It was validated at different resolutions and for different extents. It was found that the mapping procedure worked very well at farm resolution. At the extent and resolution relevant for precision farming, i.e. within-field variation, the regional models performed worse. However, this could be remedied to some extent by using a few soil samples to choose the locally best model. This approach will be implemented in an interactive web application, where farmers can provide soil samples to locally improve regional soil maps for their own fields.
