The object of this invention is the reduction of water consumption in the irrigation of crops and fertilizer. The invention is a three-piece device that coupled to the drip irrigation system channels the water to the roots minimizing losses. These three pieces are : a ring with two rigid tongues (fig.2) that is inserted in the screw cap (fig.1) and a probe by earth (fig. 3 and 4). The probe has two semicircular cavities in the upper part (8) into which the drip irrigation rubber is inserted and for its clamping the screw cap (5) is screwed with the two-tabs ring (6). This invention has agricultural purposes, which are a better use of water resources and fertilizers. Its production, installation and maintenance costs are not very high, being accessible to the farmer. (Machine-translation by Google Translate, not legally binding)
