PCT No. PCT/NO97/00049 Sec. 371 Date Feb. 5, 1999 Sec. 102(e) Date Feb. 5, 1999 PCT Filed Feb. 14, 1997 PCT Pub. No. WO97/29626 PCT Pub. Date Aug. 21, 1997In a method for periodic depositing of liquid manure such as a slurry in a soil (80) the slurry is injected in a concentrated jet (9) under pressure with the result that forms and fills a groove (6) in the soil, which groove (6) is preferably closed after the injection. A device (1) for use in the method comprises at least one nozzle (5) with a breaker element (10) for periodic interruption of or opening for an injection jet (9) in an outlet direction (P2), the nozzle preferably being provided as an opening from a chamber (3, 29, 35, 38, 52, 72) pressurized with slurry. The breaker element (10) may be rotatably mounted about a rotation axis (22) which is parallel to the nozzle's outlet direction (P2), and is located beside the nozzle (5), with the result that during a rotational movement of the breaker element periodically interrupts the injection jet (9). |
