Abstract: Low-pressure irrigation of fields is carried out simultaneously through a plurality of flexible hoses of equal length, one end of which is connected to a water supply, while the other end is open. The hoses are stretched out in parallel alignment across the field to be irrigated, preferably one hose each between two rows of plants, and all hoses are simultaneously gathered so that their open ends travel over the ground at slow uniform speed while water pours out of the open ends and irrigates the soil. When the open ends of the hoses have reached a point near the water supply, water is turned off and the hoses are transported to another field portion and stretched out in similar fashion. An apparatus for carrying out this irrigation method comprises a slowly rotated shaft which carries grooved pulleys distanced according to the hose distances, one pulley per hose.
