ABSTRACT:
The device consists of a wall (4-7) surrounding a reservoir (9) for the water, this wall having at the top a tightly sealable (11) opening (12) for introduction of the water and at the bottom two passages (17, 18) for the discharge of water and the entrance of air. The wall areas provided with the passages (17, 18) directly adjoin the soil to be irrigated.
The device can be constituted by a container (1) with a double-walled shell (2) and bottom (3). In this arrangement, two passages (17, 18) are provided in the downwardly curved inner wall (7) of the bottom (3), the spacing between these passages being dimensioned to be small.
The irrigation device is simple and inexpensive. It discharges only the quantity of water required by the plants so that the water reservoir lasts for a long time and danger of bogginess of the soil is avoided.
