the invention relates to a device for irrigtion underground and injection of water into the soil, water diffiseur buried with integrated or separate devices. the first component of the invention is a cover constuti\u00e9 \"(1.1.1), a grid (1.1) with small mesh net and a plastic wire, with or without a distributor (1).a porous layer is integrated in the space between the lid milliimetrique (1.1.1) and the distributor (1) or between the lid and the grid (1.1). this porous layer consisting of a porous material or other materials, facilitating the diffusion of water into the underlying soil (1.3).the diffuser consists of three different models: the buried irrigation maraich\u00e8re player or any other similar plants, aromatic, madicinales or ormenentales) in field and greenhouse, the diffuser with reservoir for irrigation of plants, aromatic. it in pots or ornamental stones, the irrigation of the fruit trees,forest and ornamental). the second component of the invention is a device for controlling the water flow of irrigation water can be circulated efficiently in the network. the device may be integrated or separate. the device consists of an element and a female element (1.2.10) male (1.2.5). between these two elements is a joint (3).(9) etancheit\u00e9 rubber and a porous element (18) made of porous polyurethane or other rigid material, granular, and flexible. the devices may have an additional element composed of polyurethane or other rigid or flexible porous materaiu, granular, filter (1.2.6).it has the function of filtration of the water to prevent clogging of the device. different models of the integrated device are provided for measuring tank, diffuser with plants in pots, for irrigation of crops maraich\u00e8res integrated measuring device for irrigation, serpar\u00e9 trees.these devices can operate from low pressure (0,05bar) and very low (0005bar) of irrigation water, and can provide low flow during 24heurs (10 ml).with these two components, the invention prov
