A gravity irrigation system includes a distribution piping having apertures to distribute water to a field, and a valve located upstream of the distribution piping. The valve limits a pressure of the water being delivered to the distribution piping. The system also includes a sump to receive the water at a lowest elevation of the field, a depth sensor disposed within the sump, and a return pump disposed at least partially within the sump to move the water to an elevated portion of the field. The system also includes a motor to drive the return pump, and a power source coupled to a variable frequency drive that powers the motor and controls a motor speed proportionately to an indication of the depth sensor. The system also includes a transfer piping to bring the water from the return pump to a check valve and to the distribution piping.

A smart root watering system is disclosed. The system includes a controller, configured to control the system using artificial neural networks. The system further comprises vertical tubes, inserted into the soil proximity to the roots of trees and configured to deliver water to the roots of trees. The vertical tubes include a motion sensor, configured to detect variation in water flow and wirelessly send data to the controller, thereby indicating faults of the vertical tubes to the user via a handheld electronic device. The vertical tube further includes a mechanical valve with a floater, configured to regulate input water to the system with respect to the soil absorption. The system further comprises a sensor device, configured to detect the humidity level and send to the controller. The controller is further configured to estimate the required volume of water and open an electric valve for supplying water to the roots of trees.

A convenient, water-saving and labor-saving FROG irrigation controller and system are provided, which determine the appropriate water budget and schedule for the property's landscaping based on evapotranspiration data for the geographic area, any regulation data, and property-specific data, with consideration given to reduction in watering days, increase in soil watering depth, and day of year. Once set, the FROG controller provides incremental adjustments over the course of the year; the homeowner no longer needs to re-set the watering program seasonally to automatically comply with local mandated and voluntary watering restrictions. One aspect provides a web-based wizard that is used to determine a customized water budget/schedule which is input into the FROG controller. Another aspect provides an integration of a network of FROG controllers with a central command unit.

A method and system for use therein for providing O.sub.2 and H.sub.2 gases directly to the soil proximal to the roots of plants via electrolysis is described. The method employs at least one electrolyzer disposed adjacent to, or inline with, the irrigation waterline of the plant grow operation to facilitate the introduction of the gases to the soil. A power source is used to provide the electrolytic conversion, and gases remain in a micro-bubbled form to flow through the waterline more easily to the plants where they are needed the most. A venturi is used to channel the dissolved gases in the waterline from the electrolyzer in embodiments having an external HyGrO unit. The inline embodiment electrolyzes the water without need of a venturi to reintroduce the gases to the waterline.

A drip irrigator for film-mulching drip irrigation, a film-mulching irrigation assembly and an installation method of the film-mulching irrigation assembly are provided. The drip irrigator includes a main pipeline, branch pipes and emitters. Emitter are arranged on an upper surface of the branch pipe and communicate with the branch pipe, water outlet holes are formed in inner and outer ring walls of an annular pipeline, and an opening end of the main pipeline communicates with a water conveying pipeline. By arranging emitters on the upper surface of each branch pipe, the emitters can be effectively prevented from being blocked by wet soil. Meanwhile, the water outlet holes can perform the drip irrigation to the ground simultaneously, and the overall efficiency of drip irrigation to the soil is guaranteed.
