Method and device for periodic depositing of liquid manure such as slurry in a soil

A device adapted to be supplied with pressurized liquid manure for periodic injection of a concentrated jet of the liquid manure into a soil, the device comprising means defining a chamber to receive the pressurized liquid manure, nozzle means defining at least one nozzle opening for discharging the concentrated jet of pressurized liquid manure in a direction from the chamber to the soil, and a breaker element, the breaker element being rotatably mounted about a rotation axis for continuous movement relative to the nozzle means to cause periodic interruption of the jet of pressurized liquid manure into the soil at intervals depending on speed of relative rotation of the nozzle means and the breaker element, wherein the breaker element comprises a rectangular plate or a cross.
