Abstract: The invention relates to a mechanism, intended for assembly on an irrigation emitter, which includes a cylindrical housing (2) in which the pressure of the water flowing through the emitter moves a first disc-shaped part (3), thus rotating a tubular body (7) which in turn rotates a cylindrical part (9) which is connected to a second disc-shaped part (12), to which end screws (15) are connected, the extent to which said screws are tightened defining in the displacement and rotation of the parts the operation of the emitter during either one of the possible time periods relative to the total time commanded by the irrigation controller.

Abstract: Using as a raw material solid fertilizer housed in a tight container (1) with a hermetic closure and having a container holder in which said container can be housed in a tight-fitting manner, connected to a bypass (10-11) of the general irrigation pipe (13), such that the water diverted by said bypass penetrates the container (1), dissolves the fertilizer and exits in order to be directed back to the irrigation pipe, the invention is focused on providing a pressure regulator assembly, based on a pressure controller (23), a check valve (24), a safety valve (25) and a small pipe which opens out into a normally closed depressurization valve (26), this pressure regulator feeding a “Venturi” type fertilizer solution injector element (27), which is also connected to the upper portion of the container holder for the evacuation of air (39).

Abstract: The invention relates to a method of extracting contents from sealed flexible containers using irrigation water, to a device for implementing same and to the container used. The inventive method essentially comprises the following steps: a) perforation of the container (1) with the closure of a container support (10); b) injection of irrigation water into the container (1) through the perforations thus produced; c) breakage of the container, by applying same against breaking means comprising projecting elements (16) that are disposed on the container support (10), such that the container (1) is subjected to the pressure of the irrigation water; and d) extraction of the soluble fertiliser (3) contained in the container (1) by means of the stream of irrigation water.
