Title: Method of distribution and disposal of manure
Inventor: STILES ROGER ALAN GEORGE BARRI
IPC: A01C23/00
Filed: 1990-08-20
Abstract: A method of distributing manure slurry is disclosed in which the slurry is divided into discrete doses and each dose is deposited on land at regularly spaced intervals. Preferably distribution is achieved by moving a slurry containing vehicle over land, dividing the slurry into discrete doses and depositing each dose on the land surface. The doses may be obtained by feeding the slurry to a tube associated with a rotating disc having at least one aperture and which obstructs the slurry flow except when the aperture passes the tube to release a dose of slurry. Alternatively the slurry may be fed through a peristaltic pump with an intermittent drive or fed to an auger feed terminating in a pressurized flap. There is also described a vehicle for depositing manure slurry comprising a tank portion capable of storing the slurry, a dosimeter system adapted to receive the slurry and measure it into discrete doses and deposit means adapted to place the doses at predetermined intervals on the surface over which the vehicle passes.
