An agricultural row unit assembly includes an attachment frame configured for attachment to a tow bar that is movable in a direction of travel. A proximal end of a swing-arm is coupled to the attachment frame, and an opener disk is mounted to and offset from a distal end of the swing-arm for forming a furrow. A deflecting disk is mounted to the distal end for deflecting debris from entering the furrow, and is mounted between the distal end of the swing-arm and the opener disk. The deflecting disk has a top peripheral edge spaced away from a top peripheral edge of the opener disk. A support bracket is attached as a cantilevered structure depending from the proximal end of the swing arm and extends in a space between the top peripheral edges. A tube is routed long the support bracket for dispensing a material into the furrow.
