A fluid control system for controlling one or more branches of a fluid delivery system, which can be manually controlled or, under general operating conditions, automatically controlled by ambient moisture conditions. When applied to sprinkler and irrigation systems, for example, the system will include a ground moisture sensor which, with associated means, can modify or adjust the preset watering times in accordance with soil needs as sensed by the sensor structure. The programmable timer is used for respective watering stations; the timers can be separately set to desired average watering time needed for particular stations. Sequencing functions and apparatus are also provided.

In combination, a water delivery system having a series of branches, first means for controlling said water delivery system to sequence the operation of said branches and to time the operating times of said branches, and second means coupled to said first means, and including a pair of mutually spaced probes, for modifying and locking in, prior to water delivery startups, any preset water delivery timing, thereby so modifying water delivery, by increasing and decreasing the same, in accordance with ambient soil conditions.
