A sprinkler. A stationary base includes a turbine to drive an upper housing. A plurality of sprinkler nozzle assemblies mounted on the upper housing include low voltage solenoids that are energized via slip ring contacts, with a power discontinuous slip ring located on the base. When powered, the solenoids open to allow water to be directed from the nozzle in the sprinkler nozzle assembly. the nozzles are sized, shaped, and directed to apportion water as needed to provide average water quantities amongst parts of irregularly shaped parcels.

1. A sprinkler for watering a selected surface of a land parcel having a selected size and shape, said apparatus comprising: a sprinkler base, said sprinkler base comprising a lower housing defined by a sprinkler base inner side wall, said sprinkler base comprising an inlet for receiving a pressurized water flow, an inlet turbine operably fixed in the base, a gear train having an output gear responsive to the inlet turbine;an upper housing, said upper housing rotatably coupled to said sprinkler base, said upper housing driven by said output gear, said upper housing configured for receiving water from said base, said upper housing further comprising at least one sprinkler nozzle assembly, said at least one sprinkler nozzle assembly secured to and rotatable with the upper housing, the sprinkler nozzle assembly comprising a nozzle, a solenoid valve, and an outlet nozzle; anda set of discontinuous slip ring contacts, said set of discontinuous slip ring contacts including a ground ring and powered segments, said powered segments connected with a low voltage power source for energizing said solenoid valve, wherein during rotation of said upper housing, said discontinuous slip ring contacts turn said solenoid valve on when adjacent said powered segments, and off when not adjacent powered segments, to thereby control output of water from said nozzle. 2. The sprinkler as set forth in claim 1, wherein a plurality of sprinkler nozzle assemblies are provided, and wherein a solenoid valve V is provided for each sprinkler nozzle assembly A. 3. The sprinkler as set forth in claim 2, wherein said upper housing comprises at least a first side, and wherein a first group of nozzles are provided on the first side. 4. The sprinkler as set forth in claim 3, wherein said upper housing further comprises a second side, and wherein second group of nozzles are provided on the second side. 5. The sprinkler as set forth in claim 2, wherein said upper housing comprises X sides, wherein X is a positive integer, and wherein a group of sprinkler nozzle assemblies is provided on each of said X sides. 6. The sprinkler as set forth in claim 5, wherein each nozzle in said group of sprinkler nozzle assemblies is provided having a selected outlet diameter D, and wherein said selected outlet diameter D varies amongst nozzles in said group of sprinkler nozzle assemblies. 7. The sprinkler as set forth in claim 6, wherein sprinkler nozzle assemblies in each group of sprinkler nozzle assemblies are mounted in a vertical array, one above another. 8. The sprinkler as set forth in claim 7, wherein the outlet diameter D of nozzles in each group of sprinkler nozzle assemblies varies between sprinkler nozzle assemblies in each vertical array. 9. The sprinkler as set forth in claim 8, wherein the outlet diameter D in each group of sprinkler nozzle assemblies varies vertically. 10. The sprinkler as set forth in claim 9, wherein the outlet diameter D in each group of sprinkler nozzle assemblies decreases vertically in an upward direction. 11. The sprinkler as set forth in claim 9, wherein the outlet diameter D in each group of sprinkler nozzle assemblies decreases vertically in a downward direction. 12. The sprinkler as set forth in claim 1, wherein said upper housing further comprises an annular gear, and wherein said output gear drives said annular gear, rotating the upper housing. 13. The sprinkler as set forth in claim 1, wherein said discontinuous, powered portions of said slip rings are located at or near the top of said base. 14. The sprinkler as set forth in claim 13, wherein each of said solenoids is connected to a ground slip portion of ring at all times. 15. The sprinkler as set forth in claim 13, wherein each of said solenoids are connected to a contact that rotates with said upper housing, and provides connection to said discontinuous powered portions of said slip ring, when adjacent thereto. 16. The sprinkler as set forth in claim 15, wherein said at least one sprinkler nozzle assembly comprises a group of sprinkler nozzle assemblies, and wherein within said group, during rotation of the sprinkler, selected nozzle assemblies in said group intermittently turn on and off, as set up to meet water requirements of a land parcel. 17. The sprinkler as set forth in claim 16, wherein nozzles in said group of nozzle assemblies each have a diameter D, and wherein said a diameter D of each nozzle is sized and shaped to provide water quantities correlated to water delivery through its sprinkler nozzle assembly, for watering a surface of a land parcel having a selected size and shape. 18. The sprinkler as set forth in claim 17, wherein said nozzles N in said sprinkler each have nozzle diameters D selected to deliver water a selected range of radial distances R from said sprinkler, for watering a surface of a land parcel having a selected size and shape. 19. The sprinkler as set forth in claim 18, wherein said nozzles N in said sprinkler each have nozzle diameters D, which in co-operation with said sprinkler nozzle assembly and with said solenoids, deliver a selected volume of water along a selected radial for a radial distance R from said sprinkler, for watering a surface of a land parcel having a selected size and shape. 20. The sprinkler as set forth in claim 1, further comprising a generally cylindrical outer housing, said outer housing having an outer diameter OD approximately corresponding to the spacing between distal ends of nozzles in first and second groups of nozzles oriented at one hundred eighty degrees from each other.
