Abstract: A technique of hydroponic sand culture of vegetables has been recently developed in French Guyana with a surface irrigation based on a drip system. Efforts to simplify this method have led to the use of a porous tubing buried in the sand of the cultivation tank. Two experiments are described for the development of such technique. The choice of a proper water pressure allows it to irrigate continuously. The flow rate of irrigation water through the porous material of the tubing is increased or reduced by the water tension in the sand. Curves of water use compared with the évapotranspiration show a close relation.
