The present disclosure relates to a networked ecological conservation water-saving system for urban mass green land, comprising 5-9 ecological conservation water-saving devices which are orderly arranged in the urban green land per square meter. The ecological conservation water-saving devices are arranged in a central symmetry manner. Each ecological conservation water-saving device comprises a columnar housing and an infiltrating irrigation unit. A first water storage unit is provided at the center of each infiltrating irrigation unit, and a second water storage unit is provided at the lower part of each first water storage unit. The networked ecological conservation water-saving system further comprises a first water delivery pipe network, a second water delivery pipe network, and a third water delivery pipe network.

A method is for prevention and/or biological control of wilt caused by Ralstonia solanacearum, by use of suitable bacteriophages. In addition a method uses the structural characterisation, genome sequence and activity of three specific lytic bacteriophages of R. solanacearum. Podovirus presents an elevated stability between 4 C. and 30 C. in an aqueous medium in the absence of a host. As a result of the high level of stability, lytic activity, elevated specificity towards R. solanacearum and the absence of activity against the microbiota associated with the plants to be protected, bacteriophages are used for the biological control of R. solanacearum in river courses and irrigation water, as well as in a method for preventing and/or controlling the wilt produced by the bacteria, in which at least one of the bacteriophages, or combinations thereof, are delivered to the plants and/or the soil in the irrigation water.

A geothermal aerification system includes a basin for storing water and a network of geothermal piping in fluid communication with the basin. The network of geothermal piping is configured to adjust a temperature of the water and is located at a depth below a ground surface to circulate the water to selectively absorb geothermal energy to increase a temperature of the water, or to dissipate heat to decrease the temperature of the water. The system also includes a network of water distribution pipes in fluid communication with the basin. The network of water distribution pipes is configured to discharge the water at the adjusted temperature proximate to the ground surface.

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 subsurface irrigation system dries subsurface soil with a tube that is structured to emit water to subsurface soil. The tube has a plurality of emitters that are spaced apart at fixed intervals along the tube and disposed through a wall of the tube. The tube receives water from subsurface soil through the plurality of emitters. The water discharges through a flush pipe of the subsurface irrigation system. The subsurface soil dries passively as water discharges through the flush pipe when a flush valve connected to the flush pipe is open. A vacuum installed on the flush valve may hasten removal of water from subsurface soil. Subsurface soil dries actively as air is introduced into the subsurface soil through the plurality of emitters when the flush valve is open. The subsurface soil is irrigated when water emits through the plurality of emitters when the flush valve is closed.

This invention is related to a gravity flow, multipurpose bidirectional nonpressurized climate smart subirrigation conduit apparatus for managing soil moisture and growing plants. The subirrigation conduit apparatus creates a suspended virtual water table at the desired buried depth, thus creating a anaerobic saturated zone and a capillary fringe. The capillary fringe is describe in the art as a moisture zone that has perfect air and moisture mixture for plant growth, can also be used to irrigate with high turbidity obstruction liquids such as precipitation runoff and alternative waters such as untreated greywater. When too much water is present within the landscape, the Multipurpose bidirectional nonpressurized climate smart subirrigation conduit apparatus can be used in reverse flow to drain the landscape. Bidirectional nonpressurized flow is achieved by gravity water equalization thus cutting any need for energy consumption.
