US Patent 9554098 Residue monitoring and residue-based control

A computer-implemented method and a control system are described for controlling operations involving residue. The method and system include analyzing residue on an agricultural field. A first image is captured with an image sensor of an area of the field that is ahead of or behind the implement. The first image is analyzed to determine an indicator of residue coverage on the field. A subsequent operation on the field is executed, one or more aspects of which are controlled based upon the determined indicator of residue coverage.
