Self-contained ecological watering system, protected against obturations, and capable of irrigating at low cost uniformly and regularly a variety of cultivated areas; the system operates automatically a series of fertirrigation cycles requiring minimum actuation power and reduced water flow rate. The system permits implementation of various configuration including a plurality of local subsystems (1) which are controllable locally or from a remote station (6); each subsystem comprises a container (2) capable of accumulating the volume of liquid to be discharged per cycle, a watering assembly (3) capable of regulating the watering volume and discharging it upon receiving a low power signal; a low consumption electronic control unit (4) capable of determining the frequency and the appropriate time to send said signal; and a low restriction distribution network (5) capable of transporting the water to irrigate the locations in need.

[ What is claimed is:] [1.]1. A self-sustained ecological irrigation system capable to produce repeated cycles of uniform located irrigation into a cultivated area, of the type comprising a plurality of local subsystems (1) assisting generally different and physically apart cultivated areas; said local subsystems being linked with a central station (6) to receive remote control; said central station comprising codifying, adressing and transmitter circuits capable to send remote control orders with sufficient energy to be received by the adressed local subsystems (1); characterized in that each one of said local subsystems (1) comprises a liquid container (2) with enough capacity to contain at least the total water volume to be irrigated during one cycle, being the container (2) hydraulically joined from its bottom zone with a positionable watering actuator assembly (3); said positionable watering actuator assembly (3) being by one side electrically connected to receive control signals, with a watering command assembly (4) capable to determine the characteristics of the watering cycle and command their execution; and being by the other side hydraulically joined to feed a low friction losses watering distribution network (5), capable to subdivide uniformly the discharged volume of liquid and emitting it in located points into the cultivation area; said positionable watering actuator assembly (3) comprising a recipient hermetically closed by a top cover; said recipient including a first filling controller subset (16) driven by the relief of pressurized air, able to controllably limit the irrigation water entrance to the recipient from an external source; a second discharge actuator subset (24) providing at least one dimensionally defined threshold level of controlled triggerable discharge driven by the relief of pressurized air; being said discharge actuator subset (24) able to transit abruptly fiom a closing state to another of full open passage with low friction losses, if being surpassed said threshold by the current level of the liquid; both first and second subsets being fixedly height positioned one relative to the other, in funtion of the desired relationship among the designed filling and discharge threshold levels already mentioned; said positionable watering actuator assembly also comprising externally fixed to the top cover of said recipient, at least one trigger discharge device (44) able to relieved pressurized air, connected to control at least one of the above mentioned subsets; said trigger discharge device (44) presenting meanss of electrical connection to receive from said watering command assembly (4), impulsive activating signals for change of state; said positionable watering actuator assembly (3), at last comprising a mechanism for vertical positioning of itself in reference to the desired level of filling of the mentioned container (2).
