An agricultural device associated with reduced tillage techniques in a field includes a frame and a separator supported by the frame. The separator is configured to form a strip of exposed soil in residual plant matter in the field. A crimping device associated with the separator is configured to at least partially crush stems of residual plant matter while maintaining the strip.
