A soil moisture auto control system which can be used in subsurface irrigation, outer space agricultural farm irrigation, semi-arid and arid agricultural areas irrigation and nutrients addition, as well as auto watering and nutrients addition devices for flower and/or vegetable pots in indoor planting, by an external negative pressure design system responding to soil moisture needs by plants in the agricultural areas by bi-directional flows arrangements to automatically adjust moisture needs for plants.

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.

This invention relates to a sprinkler head conversion sleeve/base member made of durable plastic, it is comprised of a cylindrical sleeve having an opening at the upper end with an external thread for attachment to a gear driven sprinkler head. The lower end of said sleeve having an external thread for attachment to the internal threads of an in-ground sprinkler housing. The open bottom of the sleeve receives water from the lower chamber of the existing sprinkler housing with no direct connect to a pressurized water system, water enters from either the bottom or the side orifice with no additional plumbing. The sleeve also supports internal protrusions which facilitate the mechanical operation of a gear driven sprinkler head used in conjunction with my sleeve The gear driven head referenced numerous times in this application is not part of this application. The embodiment of this invention is a single sleeve with characteristics outlined above and in the claims and description.

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.
