The arrangement (1) has a tubular frame with longitudinal beams (10, 11) and cross beams, serving as a tank (2). The longitudinal beams are designed for conveying of fertilizer. A tank is filled with the fertilizer and supported by the tank. Two distributor heads (14, 15) apply the fertilizer on a farm area. Two pumps (6, 7) e.g. rotary piston pumps, the longitudinal beams that are formed as pressure lines and two way valves (12, 13) e.g. 3/2 valves, are provided upstream to the distributor heads. The control valves are switched independent of each other.
