PCT No. PCT/SE82/00319 Sec. 371 Date Jun. 16, 1983 Sec. 102(e) Date Jun. 16, 1983 PCT Filed Oct. 6, 1982 PCT Pub. No. WO83/01364 PCT Pub. Date Apr. 28, 1983.A cultivation plant comprising several separate water accumulators (1) which are buried under a ground area (5) in which plants are to be grown, and which water accumulators are formed as a closed container (11) which is filled with a porous, water-soaking substrate (13) which opens to the ground to be irrigated over openings (12) at the top or at the side of the water accumulator (1). Each water accumulator is separately connected to a central force for supply of water and for supply of air. When using the cultivation plant water is supplied to the porous, water-soaking substrate (13) until the substrate has reached a predetermined maximum degree of moisture, whereafter the water supply is ceased, whereas air is supplied to the substrate (13) at a pressure which is slightly higher than the static pressure of the substrate, so that the air is forced through the substrate and out into the irrigated ground for oxygenating same. Water and air supply can be made alternating or concurrently, whereby the supply of air is continued even after the supply of water has been ceased.
