The device has a conveyor assembly for conveying liquid economic fertilizer i.e. liquid manure, and a tank filled with the fertilizer. A distributor applies the fertilizer to an agricultural land, and a displacement pump with a defined conveying volume conveys the liquid fertilizer besides the distributor and is operated by a speed adjusted power-takeoff of a tractor. A computing device calculates rotation speed of the power-takeoff depending on an amount of fertilizers, running speed and working width of the device and transfers data to the tractor by a data bus i.e. ISObus. The displacement pump is designed as a rotary piston or eccentric spiral pump, and the distributor is designed as a dragging hose distributor or a liquid manure injectory. |
