<p>An irrigation system for controlling localised watering of a plant or crop including: (a) a vessel (1) for storing a predetermined volume of liquid, the vessel (1) having an inlet (7) connectable to an external liquid source to enable ingress of liquid from the external source into the vessel (1), (b) a first valve means (9) operable within the vessel (1) and located proximal to the inlet (7) such that the liquid level within the vessel (1) is maintained between first and second liquid levels, (c) a liquid transfer means (16) having a first end (17) in communication with liquid stored within the vessel (1), and a second end (18) located external to the vessel (1), wherein liquid from the vessel (1) is transferred at a predetermined controlled rate to the local environment wherein a volume of liquid is maintained in the vessel (1) such that as the liquid level reaches a first lower predetermined level, the first valve means (9) is actuated to allow ingress of liquid from the external source via the inlet (7) to the second upper predetermined level so that liquid is available for repeated transfer and release to the local environment, wherein the maintenance of water within the vessel (1) is cyclical.</p> |
