Embodiments of the invention relate to an apparatus for discharging a fertilizer in strips onto agriculturally productive land by trailing hoses, which apparatus is designed for installing on the rear of a tank vehicle, with two jibs which can each be pivoted to and fro about a vertical axis (A1, A2) between a discharge position and a transport position. Certain embodiments relate in particular to an apparatus of this type which has a supporting device which is arranged on the apparatus so as to be pivotable about a vertical axis (B) and is designed, in the transport position, to support the jibs in relation to the carriageway in a supporting section spaced apart from the axis (B). Embodiments also relate to a tank vehicle with an apparatus of this type.
